 INTERNET MESSAGE ACCESS PROTOCOL - VERSION 4rev1
|
|
Summary Publication date: Mar 2003 The Internet Message Access Protocol, Version 4rev1 (IMAP4rev1) allows a client to access and manipulate electronic mail messages on a server. IMAP4rev1 permits manipulation of mailboxes (remote message folders) in a way that is functionally equivalent to local folders. IMAP4rev1 also provides the capability for an offline client to resynchronize with the server. IMAP4rev1 includes operations for creating, deleting, and renaming mailboxes, checking for new messages, permanently removing messages, setting and clearing flags, RFC 2822 and RFC 2045 parsing, searching, and selective fetching of message attributes, texts, and portions thereof. Messages in IMAP4rev1 are accessed by the use of numbers. These numbers are either message sequence numbers or unique identifiers. IMAP4rev1 supports a single server. A mechanism for accessing configuration information to support multiple IMAP4rev1 servers is discussed in RFC 2244. IMAP4rev1 does not specify a means of posting mail; this function is handled by a mail transfer protocol such as RFC 2821. |
| RFC 3502 |
Internet Message Access Protocol (IMAP) - MULTIAPPEND Extension
|
|
Summary Publication date: Mar 2003 This document describes the multiappending extension to the Internet Message Access Protocol (IMAP) (RFC 3501). This extension provides substantial performance improvements for IMAP clients which upload multiple messages at a time to a mailbox on the server. A server which supports this extension indicates this with a capability name of "MULTIAPPEND". |
| RFC 3503 |
Message Disposition Notification (MDN) profile for Internet Message Access Protocol (IMAP)
|
|
Summary Publication date: Mar 2003 The Message Disposition Notification (MDN) facility defined in RFC 2298 provides a means by which a message can request that message processing by the recipient be acknowledged as well as a format to be used for such acknowledgements. However, it doesn't describe how multiple Mail User Agents (MUAs) should handle the generation of MDNs in an Internet Message Access Protocol (IMAP4) environment. This document describes how to handle MDNs in such an environment and provides guidelines for implementers of IMAP4 that want to add MDN support to their products. |
| RFC 3504 |
Internet Open Trading Protocol (IOTP) Version 1, Errata
|
|
Summary Publication date: Mar 2003 Since the publication of the RFCs specifying Version 1.0 of the Internet Open Trading Protocol (IOTP), some errors have been noted. This informational document lists these errors and provides corrections for them. |
| RFC 3505 |
Electronic Commerce Modeling Language (ECML): Version 2 Requirements
|
|
Summary Publication date: Mar 2003 This document lists the design principles, scope, and requirements for the Electronic Commerce Modeling Language (ECML) version 2 specification.

| RFC 3506 |
Requirements and Design for Voucher Trading System (VTS)
|
|
Summary Publication date: Mar 2003 Crediting loyalty points and collecting digital coupons or gift certificates are common functions in purchasing and trading transactions. These activities can be generalized using the concept of a "voucher", which is a digital representation of the right to claim goods or services. This document presents a Voucher Trading System (VTS) that circulates vouchers securely and its terminology; it lists design principles and requirements for VTS and the Generic Voucher Language (GVL), with which diverse types of vouchers can be described. |
| RFC 3507 |
Internet Content Adaptation Protocol (ICAP)
|
|
Summary Publication date: Apr 2003 ICAP, the Internet Content Adaption Protocol, is a protocol aimed at providing simple object-based content vectoring for HTTP services. ICAP is, in essence, a lightweight protocol for executing a "remote procedure call" on HTTP messages. It allows ICAP clients to pass HTTP messages to ICAP servers for some sort of transformation or other processing ("adaptation"). The server executes its transformation service on messages and sends back responses to the client, usually with modified messages. Typically, the adapted messages are either HTTP requests or HTTP responses. |
| RFC 3508 |
H.323 Uniform Resource Locator (URL) Scheme Registration
|
|
Summary Publication date: Apr 2003 ITU-T Recommendation H.323 version 4 introduced an H.323-specific Uniform Resource Locator (URL). This document reproduces the H323- URL definition found in H.323, and is published as an RFC for ease of access and registration with the Internet Assigned Numbers Authority (IANA). |
| RFC 3509 |
Alternative Implementations of OSPF Area Border Routers
|
|
Summary Publication date: Apr 2003 Open Shortest Path First (OSPF) is a link-state intra-domain routing protocol used for routing in IP networks. Though the definition of the Area Border Router (ABR) in the OSPF specification does not require a router with multiple attached areas to have a backbone connection, it is actually necessary to provide successful routing to the inter-area and external destinations. If this requirement is not met, all traffic destined for the areas not connected to such an ABR or out of the OSPF domain, is dropped. This document describes alternative ABR behaviors implemented in Cisco and IBM routers. |
| RFC 3510 |
Internet Printing Protocol/1.1: IPP URL Scheme
|
|
Summary Publication date: Apr 2003 This memo defines the "ipp" URL (Uniform Resource Locator) scheme. This memo updates IPP/1.1: Encoding and Transport (RFC 2910), by expanding and clarifying Section 5, "IPP URL Scheme", of RFC 2910. An "ipp" URL is used to specify the network location of a print service that supports the IPP Protocol (RFC 2910), or of a network resource (for example, a print job) managed by such a print service. |
| RFC 3511 |
Benchmarking Methodology for Firewall Performance
|
|
Summary Publication date: Apr 2003 This document discusses and defines a number of tests that may be used to describe the performance characteristics of firewalls.

In particular, it offers guidance in the effective use of SNMP for configuration management. This information is relevant to vendors that build network elements, management application developers, and those that acquire and deploy this technology in their networks. |
| RFC 3513 |
Internet Protocol Version 6 (IPv6) Addressing Architecture
|
|
Summary Publication date: Apr 2003 This specification defines the addressing architecture of the IP Version 6 (IPv6) protocol. The document includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses. |
| RFC 3514 |
The Security Flag in the IPv4 Header
|
|
Summary Publication date: Apr 2003 Firewalls, packet filters, intrusion detection systems, and the like often have difficulty distinguishing between packets that have malicious intent and those that are merely unusual. We define a security flag in the IPv4 header as a means of distinguishing the two cases. |
| RFC 3515 |
The Session Initiation Protocol (SIP) Refer Method
|
|
Summary Publication date: Apr 2003 This document defines the REFER method. This Session Initiation Protocol (SIP) extension requests that the recipient REFER to a resource provided in the request. It provides a mechanism allowing the party sending the REFER to be notified of the outcome of the referenced request. This can be used to enable many applications, including call transfer. In addition to the REFER method, this document defines the the refer event package and the Refer-To request header. |
| RFC 3516 |
IMAP4 Binary Content Extension
|
|
Summary Publication date: Apr 2003 This memo defines the Binary extension to the Internet Message Access Protocol (IMAP4). It provides a mechanism for IMAP4 clients and servers to exchange message body data without using a MIME content- transfer-encoding. |
| RFC 3517 |
A Conservative Selective Acknowledgment (SACK)-based Loss Recovery Algorithm for TCP
|
|
Summary Publication date: Apr 2003 This document presents a conservative loss recovery algorithm for TCP that is based on the use of the selective acknowledgment (SACK) TCP option. The algorithm presented in this document conforms to the spirit of the current congestion control specification (RFC 2581), but allows TCP senders to recover more effectively when multiple segments are lost from a single flight of data. |
| RFC 3518 |
Point-to-Point Protocol (PPP) Bridging Control Protocol (BCP)
|
|
Summary Publication date: Apr 2003 The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol (LCP) and proposes a family of Network Control Protocols (NCP) for establishing and configuring different network-layer protocols. This document defines the NCP for establishing and configuring Remote Bridging for PPP links. This document obsoletes RFC 2878, which was based on the IEEE 802.1D-1993 MAC Bridge. This document extends that specification by improving support for bridge control packets. |
| RFC 3519 |
Mobile IP Traversal of Network Address Translation (NAT) Devices
|
|
Summary Publication date: May 2003 Mobile IP's datagram tunnelling is incompatible with Network Address Translation (NAT). This document presents extensions to the Mobile IP protocol and a tunnelling method which permits mobile nodes using Mobile IP to operate in private address networks which are separated from the public internet by NAT devices. The NAT traversal is based on using the Mobile IP Home Agent UDP port for encapsulated data traffic. |
| RFC 3520 |
Session Authorization Policy Element
|
|
Summary Publication date: Apr 2003 This document describes the representation of a session authorization policy element for supporting policy-based per-session authorization and admission control. The goal of session authorization is to allow the exchange of information between network elements in order to authorize the use of resources for a service and to co-ordinate actions between the signaling and transport planes. This document describes how a process on a system authorizes the reservation of resources by a host and then provides that host with a session authorization policy element which can be inserted into a resource reservation protocol (e.g., the Resource ReSerVation Protocol (RSVP) PATH message) to facilitate proper and secure reservation of those resources within the network. We describe the encoding of session authorization information as a policy element conforming to the format of a Policy Data object (RFC 2750) and provide details relating to operations, processing rules and error scenarios. |
| RFC 3521 |
Framework for Session Set-up with Media Authorization
|
|
Summary Publication date: Apr 2003 Establishing multimedia streams must take into account requirements for end-to-end QoS, authorization of network resource usage and accurate accounting for resources used. During session set up, policies may be enforced to ensure that the media streams being requested lie within the bounds of the service profile established for the requesting host. Similarly, when a host requests resources to provide a certain QoS for a packet flow, policies may be enforced to ensure that the required resources lie within the bounds of the resource profile established for the requesting host. To prevent fraud and to ensure accurate billing, this document describes various scenarios and mechanisms that provide the linkage required to verify that the resources being used to provide a requested QoS are in-line with the media streams requested (and authorized) for the session. |
| RFC 3522 |
The Eifel Detection Algorithm for TCP
|
|
Summary Publication date: Apr 2003 The Eifel detection algorithm allows a TCP sender to detect a posteriori whether it has entered loss recovery unnecessarily. It requires that the TCP Timestamps option defined in RFC 1323 be enabled for a connection. The Eifel detection algorithm makes use of the fact that the TCP Timestamps option eliminates the retransmission ambiguity in TCP. Based on the timestamp of the first acceptable ACK that arrives during loss recovery, it decides whether loss recovery was entered unnecessarily. The Eifel detection algorithm provides a basis for future TCP enhancements. This includes response algorithms to back out of loss recovery by restoring a TCP sender's congestion control state. |
| RFC 3523 |
Internet Emergency Preparedness (IEPREP) Telephony Topology Terminology
|
|
Summary Publication date: Apr 2003 This document defines the topology naming conventions that are to be used in reference to Internet Emergency Preparedness (IEPREP) phone calls. These naming conventions should be used to focus the IEPREP Working Group during discussions and when writing requirements, gap analysis and other solutions documents. |
| RFC 3524 |
Mapping of Media Streams to Resource Reservation Flows
|
|
Summary Publication date: Apr 2003 This document defines an extension to the Session Description Protocol (SDP) grouping framework. It allows requesting a group of media streams to be mapped into a single resource reservation flow. The SDP syntax needed is defined, as well as a new "semantics" attribute called Single Reservation Flow (SRF). |
| RFC 3525 |
Gateway Control Protocol Version 1
|
|
Summary Publication date: Jun 2003 This document defines the protocol used between elements of a physically decomposed multimedia gateway, i.e., a Media Gateway and a Media Gateway Controller. The protocol presented in this document meets the requirements for a media gateway control protocol as presented in RFC 2805. This document replaces RFC 3015. It is the result of continued cooperation between the IETF Megaco Working Group and ITU-T Study Group 16. It incorporates the original text of RFC 3015, modified by corrections and clarifications discussed on the Megaco E-mail list and incorporated into the Study Group 16 Implementor's Guide for Recommendation H.248. The present version of this document underwent ITU-T Last Call as Recommendation H.248 Amendment 1. Because of ITU-T renumbering, it was published by the ITU-T as Recommendation H.248.1 (03/2002), Gateway Control Protocol Version 1. Users of this specification are advised to consult the H.248 Sub- series Implementors' Guide at http://www.itu.int/itudoc/itu- t/com16/implgd for additional corrections and clarifications. |
| RFC 3526 |
More Modular Exponential (MODP) Diffie-Hellman groups for Internet Key Exchange (IKE)
|
|
Summary Publication date: May 2003 This document defines new Modular Exponential (MODP) Groups for the Internet Key Exchange (IKE) protocol. It documents the well known and used 1536 bit group 5, and also defines new 2048, 3072, 4096, 6144, and 8192 bit Diffie-Hellman groups numbered starting at 14. The selection of the primes for theses groups follows the criteria established by Richard Schroeppel. |
| RFC 3527 |
Link Selection sub-option for the Relay Agent Information Option for DHCPv4
|
|
Summary Publication date: Apr 2003 This document describes the link selection sub-option of the relay- agent-information option for the Dynamic Host Configuration Protocol (DHCPv4). The giaddr specifies an IP address which determines both a subnet, and thereby a link on which a Dynamic Host Configuration Protocol (DHCP) client resides as well as an IP address that can be used to communicate with the relay agent. The subnet-selection option allows the functions of the giaddr to be split so that when one entity is performing as a DHCP proxy, it can specify the subnet/link from which to allocate an IP address, which is different from the IP address with which it desires to communicate with the DHCP server. Analogous situations exist where the relay agent needs to specify the subnet/link on which a DHCP client resides, which is different from an IP address that can be used to communicate with the relay agent. |
| RFC 3528 |
Mesh-enhanced Service Location Protocol (mSLP)
|
|
Summary Publication date: Apr 2003 This document describes the Mesh-enhanced Service Location Protocol (mSLP). mSLP enhances the Service Location Protocol (SLP) with a scope-based fully-meshed peering Directory Agent (DA) architecture. Peer DAs exchange new service registrations in shared scopes via anti-entropy and direct forwarding. mSLP improves the reliability and consistency of SLP DA services, and simplifies Service Agent (SA) registrations in systems with multiple DAs. mSLP is backward compatible with SLPv2 and can be deployed incrementally. |
| RFC 3529 |
Using Extensible Markup Language-Remote Procedure Calling (XML-RPC) in Blocks Extensible Exchange Protocol (BEEP)
|
|
Summary Publication date: Apr 2003 XML-RPC is an Extensible Markup Language-Remote Procedure Calling protocol that works over the Internet. It defines an XML format for messages that are transfered between clients and servers using HTTP. An XML-RPC message encodes either a procedure to be invoked by the server, along with the parameters to use in the invocation, or the result of an invocation. Procedure parameters and results can be scalars, numbers, strings, dates, etc.; they can also be complex record and list structures. This document specifies a how to use the Blocks Extensible Exchange Protocol (BEEP) to transfer messages encoded in the XML-RPC format between clients and servers. |
| RFC 3530 |
Network File System (NFS) version 4 Protocol
|
|
Summary Publication date: Apr 2003 The Network File System (NFS) version 4 is a distributed filesystem protocol which owes heritage to NFS protocol version 2, RFC 1094, and version 3, RFC 1813. Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the mount protocol. In addition, support for strong security (and its negotiation), compound operations, client caching, and internationalization have been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment. This document replaces RFC 3010 as the definition of the NFS version 4 protocol. |
| RFC 3531 |
A Flexible Method for Managing the Assignment of Bits of an IPv6 Address Block
|
|
Summary Publication date: Apr 2003 This document proposes a method to manage the assignment of bits of an IPv6 address block or range. When an organisation needs to make an address plan for its subnets or when an ISP needs to make an address plan for its customers, this method enables the organisation to postpone the final decision on the number of bits to partition in the address space they have. It does it by keeping the bits around the borders of the partition to be free as long as possible. This scheme is applicable to any bits addressing scheme using bits with partitions in the space, but its first intended use is for IPv6. It is a generalization of RFC 1219 and can be used for IPv6 assignments. |
| RFC 3532 |
Requirements for the Dynamic Partitioning of Switching Elements
|
|
Summary Publication date: May 2003 This document identifies a set of requirements for the mechanisms used to dynamically reallocate the resources of a switching element (e.g., an ATM switch) to its partitions. These requirements are particularly critical in the case of an operator creating a switch partition and then leasing control of that partition to a third party. |
| RFC 3533 |
The Ogg Encapsulation Format Version 0
|
|
Summary Publication date: May 2003 This document describes the Ogg bitstream format version 0, which is a general, freely-available encapsulation format for media streams. It is able to encapsulate any kind and number of video and audio encoding formats as well as other data streams in a single bitstream. |
| RFC 3534 |
The application/ogg Media Type
|
|
Summary Publication date: May 2003 The Ogg Bitstream Format aims at becoming a general, freely-available standard for transporting multimedia content across computing platforms and networks. The intention of this document is to define the MIME media type application/ogg to refer to this kind of content when transported across the Internet. It is the intention of the Ogg Bitstream Format developers that it be usable without intellectual property concerns. |
| RFC 3535 |
Overview of the 2002 IAB Network Management Workshop
|
|
Summary Publication date: May 2003 This document provides an overview of a workshop held by the Internet Architecture Board (IAB) on Network Management. The workshop was hosted by CNRI in Reston, VA, USA on June 4 thru June 6, 2002. The goal of the workshop was to continue the important dialog started between network operators and protocol developers, and to guide the IETFs focus on future work regarding network management. This report summarizes the discussions and lists the conclusions and recommendations to the Internet Engineering Task Force (IETF) community. |
| RFC 3536 |
Terminology Used in Internationalization in the IETF
|
|
Summary Publication date: May 2003 This document provides a glossary of terms used in the IETF when discussing internationalization. The purpose is to help frame discussions of internationalization in the various areas of the IETF and to help introduce the main concepts to IETF participants. |
| RFC 3537 |
Wrapping a Hashed Message Authentication Code (HMAC) key with a Triple-Data Encryption Standard (DES) Key or an Advanced Encryption Standard (AES) Key
|
|
Summary Publication date: May 2003 This document defines two methods for wrapping an HMAC (Hashed Message Authentication Code) key. The first method defined uses a Triple DES (Data Encryption Standard) key to encrypt the HMAC key. The second method defined uses an AES (Advanced Encryption Standard) key to encrypt the HMAC key. One place that such an algorithm is used is for the Authenticated Data type in CMS (Cryptographic Message Syntax). |
| RFC 3538 |
Secure Electronic Transaction (SET) Supplement for the v1.0 Internet Open Trading Protocol (IOTP)
|
|
Summary Publication date: Jun 2003 This document describes detailed Input/Output parameters for the Internet Open Trading Protocol (IOTP) Payment Application Programming Interface (API). It also describes procedures in the Payment Bridge for the use of SET (SET Secure Electronic Transaction) as the payment protocol within Version 1.0 of the IOTP. |
| RFC 3539 |
Authentication, Authorization and Accounting (AAA) Transport Profile
|
|
Summary Publication date: Jun 2003 This document discusses transport issues that arise within protocols for Authentication, Authorization and Accounting (AAA). It also provides recommendations on the use of transport by AAA protocols. This includes usage of standards-track RFCs as well as experimental proposals. |
| RFC 3540 |
Robust Explicit Congestion Notification (ECN) Signaling with Nonces
|
|
Summary Publication date: Jun 2003 This note describes the Explicit Congestion Notification (ECN)-nonce, an optional addition to ECN that protects against accidental or malicious concealment of marked packets from the TCP sender. It improves the robustness of congestion control by preventing receivers from exploiting ECN to gain an unfair share of network bandwidth. The ECN-nonce uses the two ECN-Capable Transport (ECT)codepoints in the ECN field of the IP header, and requires a flag in the TCP header. It is computationally efficient for both routers and hosts. |
| RFC 3541 |
A Uniform Resource Name (URN) Namespace for the Web3D Consortium (Web3D)
|
|
Summary Publication date: May 2003 This document describes a Uniform Resource Name (URN) namespace for the Web3D Consortium (Web3D) for naming persistent resources such as technical documents and specifications, Virtual Reality Modeling Language (VRML) and Extensible 3D (X3D) files and resources, Extensible Markup Language (XML) Document Type Definitions (DTDs), XML Schemas, namespaces, style sheets, media assets, and other resources produced or managed by Web3D. |
| RFC 3542 |
Advanced Sockets Application Program Interface (API) for IPv6
|
|
Summary Publication date: May 2003 This document provides sockets Application Program Interface (API) to support "advanced" IPv6 applications, as a supplement to a separate specification, RFC 3493. The expected applications include Ping, Traceroute, routing daemons and the like, which typically use raw sockets to access IPv6 or ICMPv6 header fields. This document proposes some portable interfaces for applications that use raw sockets under IPv6. There are other features of IPv6 that some applications will need to access: interface identification (specifying the outgoing interface and determining the incoming interface), IPv6 extension headers, and path Maximum Transmission Unit (MTU) information. This document provides API access to these features too. Additionally, some extended interfaces to libraries for the "r" commands are defined. The extension will provide better backward compatibility to existing implementations that are not IPv6-capable. |
| RFC 3543 |
Registration Revocation in Mobile IPv4
|
|
Summary Publication date: Aug 2003 This document defines a Mobile IPv4 Registration Revocation mechanism whereby a mobility agent involved in providing Mobile IP services to a mobile node can notify the other mobility agent providing Mobile IP services to the same mobile node of the termination of this registration. The mechanism is also usable by a home agent to notify a co-located mobile node of the termination of its binding as well. Moreover, the mechanism provides for this notification to be acknowledged. A signaling mechanism already defined by the Mobile IPv4 protocol is leveraged as a way to inform a mobile node of the revocation of its binding. |
| RFC 3544 |
IP Header Compression over PPP
|
|
Summary Publication date: Jul 2003 This document describes an option for negotiating the use of header compression on IP datagrams transmitted over the Point-to-Point Protocol (RFC 1661). It defines extensions to the PPP Control Protocols for IPv4 and IPv6 (RFC 1332, RFC 2472). Header compression may be applied to IPv4 and IPv6 datagrams in combination with TCP, UDP and RTP transport protocols as specified in RFC 2507, RFC 2508 and RFC 3545. |
| RFC 3545 |
Enhanced Compressed RTP (CRTP) for Links with High Delay, Packet Loss and Reordering
|
|
Summary Publication date: Jul 2003 This document describes a header compression scheme for point to point links with packet loss and long delays. It is based on Compressed Real-time Transport Protocol (CRTP), the IP/UDP/RTP header compression described in RFC 2508. CRTP does not perform well on such links: packet loss results in context corruption and due to the long delay, many more packets are discarded before the context is repaired. To correct the behavior of CRTP over such links, a few extensions to the protocol are specified here. The extensions aim to reduce context corruption by changing the way the compressor updates the context at the decompressor: updates are repeated and include updates to full and differential context parameters. With these extensions, CRTP performs well over links with packet loss, packet reordering and long delays. |
| RFC 3546 |
Transport Layer Security (TLS) Extensions
|
|
Summary Publication date: Jun 2003 This document describes extensions that may be used to add functionality to Transport Layer Security (TLS). It provides both generic extension mechanisms for the TLS handshake client and server hellos, and specific extensions using these generic mechanisms. The extensions may be used by TLS clients and servers. The extensions are backwards compatible - communication is possible between TLS 1.0 clients that support the extensions and TLS 1.0 servers that do not support the extensions, and vice versa. |
| RFC 3547 |
The Group Domain of Interpretation
|
|
Summary Publication date: Jul 2003 This document presents an ISAMKP Domain of Interpretation (DOI) for group key management to support secure group communications. The GDOI manages group security associations, which are used by IPSEC and potentially other data security protocols running at the IP or application layers. These security associations protect one or more key-encrypting keys, traffic-encrypting keys, or data shared by group members. |
| RFC 3548 |
The Base16, Base32, and Base64 Data Encodings
|
|
Summary Publication date: Jul 2003 This document describes the commonly used base 64, base 32, and base 16 encoding schemes. It also discusses the use of line-feeds in encoded data, use of padding in encoded data, use of non-alphabet characters in encoded data, and use of different encoding alphabets. |
| RFC 3549 |
Linux Netlink as an IP Services Protocol
|
|
Summary Publication date: Jul 2003 This document describes Linux Netlink, which is used in Linux both as an intra-kernel messaging system as well as between kernel and user space. The focus of this document is to describe Netlink's functionality as a protocol between a Forwarding Engine Component (FEC) and a Control Plane Component (CPC), the two components that define an IP service. As a result of this focus, this document ignores other uses of Netlink, including its use as a intra-kernel messaging system, as an inter-process communication scheme (IPC), or as a configuration tool for other non-networking or non-IP network services (such as decnet, etc.). This document is intended as informational in the context of prior art for the ForCES IETF working group. |
| RFC 3550 |
RTP: A Transport Protocol for Real-Time Applications
|
|
Summary Publication date: Jul 2003 This memorandum describes RTP, the real-time transport protocol. RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services. RTP does not address resource reservation and does not guarantee quality-of-service for real-time services. The data transport is augmented by a control protocol (RTCP) to allow monitoring of the data delivery in a manner scalable to large multicast networks, and to provide minimal control and identification functionality. RTP and RTCP are designed to be independent of the underlying transport and network layers. The protocol supports the use of RTP-level translators and mixers. Most of the text in this memorandum is identical to RFC 1889 which it obsoletes. There are no changes in the packet formats on the wire, only changes to the rules and algorithms governing how the protocol is used. The biggest change is an enhancement to the scalable timer algorithm for calculating when to send RTCP packets in order to minimize transmission in excess of the intended rate when many participants join a session simultaneously. |
| RFC 3551 |
RTP Profile for Audio and Video Conferences with Minimal Control
|
|
Summary Publication date: Jul 2003 This document describes a profile called "RTP/AVP" for the use of the real-time transport protocol (RTP), version 2, and the associated control protocol, RTCP, within audio and video multiparticipant conferences with minimal control. It provides interpretations of generic fields within the RTP specification suitable for audio and video conferences. In particular, this document defines a set of default mappings from payload type numbers to encodings. This document also describes how audio and video data may be carried within RTP. It defines a set of standard encodings and their names when used within RTP. The descriptions provide pointers to reference implementations and the detailed standards. This document is meant as an aid for implementors of audio, video and other real-time multimedia applications. This memorandum obsoletes RFC 1890. It is mostly backwards- compatible except for functions removed because two interoperable implementations were not found. The additions to RFC 1890 codify existing practice in the use of payload formats under this profile and include new payload formats defined since RFC 1890 was published. |
| RFC 3552 |
Guidelines for Writing RFC Text on Security Considerations
|
|
Summary Publication date: Jul 2003 All RFCs are required to have a Security Considerations section. Historically, such sections have been relatively weak. This document provides guidelines to RFC authors on how to write a good Security Considerations section. |
| RFC 3553 |
An IETF URN Sub-namespace for Registered Protocol Parameters
|
|
Summary Publication date: Jun 2003 This document describes a new sub-delegation for the 'ietf' URN namespace for registered protocol items. The 'ietf' URN namespace is defined in RFC 2648 as a root for persistent URIs that refer to IETF-defined resources. |
| RFC 3554 |
On the Use of Stream Control Transmission Protocol (SCTP) with IPsec
|
|
Summary Publication date: Jul 2003 This document describes functional requirements for IPsec (RFC 2401) and Internet Key Exchange (IKE) (RFC 2409) to facilitate their use in securing SCTP (RFC 2960) traffic. |
| RFC 3555 |
MIME Type Registration of RTP Payload Formats
|
|

The AES-XCBC-MAC-96 Algorithm and Its Use With IPsec
|
|
Summary Publication date: Sep 2003 A Message Authentication Code (MAC) is a key-dependent one way hash function. One popular way to construct a MAC algorithm is to use a block cipher in conjunction with the Cipher-Block-Chaining (CBC) mode of operation. The classic CBC-MAC algorithm, while secure for messages of a pre-selected fixed length, has been shown to be insecure across messages of varying lengths such as the type found in typical IP datagrams. This memo specifies the use of AES in CBC mode with a set of extensions to overcome this limitation. This new algorithm is named AES-XCBC-MAC-96. |
| RFC 3567 |

Signalling of Modem-On-Hold status in Layer 2 Tunneling Protocol (L2TP)
|
|
Summary Publication date: Jul 2003 The Layer 2 Tunneling Protocol (L2TP) defines a mechanism for tunneling Point-to-Point Protocol (PPP) sessions. It is common for these PPP sessions to be established using modems connected over the public switched telephone network. One of the standards governing modem operation defines procedures that enable a client modem to put the call on hold and later, re- establish the modem link with minimal delay and without having to redial. While the modem call is on hold, the client phone line can be used to place or receive other calls. The L2TP base protocol does not provide any means to signal these events from the L2TP Access Controller (LAC), where the modem is physically connected, to the L2TP Network Server (LNS), where the PPP session is handled. This document describes a method to let the LNS know when a client modem connected to a LAC has placed the call on hold. |
| RFC 3574 |

RADIUS (Remote Authentication Dial In User Service) Support For Extensible Authentication Protocol (EAP)
|
|
Summary Publication date: Sep 2003 This document defines Remote Authentication Dial In User Service (RADIUS) support for the Extensible Authentication Protocol (EAP), an authentication framework which supports multiple authentication mechanisms. In the proposed scheme, the Network Access Server (NAS) forwards EAP packets to and from the RADIUS server, encapsulated within EAP-Message attributes. This has the advantage of allowing the NAS to support any EAP authentication method, without the need for method-specific code, which resides on the RADIUS server. While EAP was originally developed for use with PPP, it is now also in use with IEEE 802. This document updates RFC 2869. |
| RFC 3580 |

| RFC 3581 |
An Extension to the Session Initiation Protocol (SIP) for Symmetric Response Routing
|
|
Summary Publication date: Aug 2003 The Session Initiation Protocol (SIP) operates over UDP and TCP, among others. When used with UDP, responses to requests are returned to the source address the request came from, and to the port written into the topmost Via header field value of the request. This behavior is not desirable in many cases, most notably, when the client is behind a Network Address Translator (NAT). This extension defines a new parameter for the Via header field, called "rport", that allows a client to request that the server send the response back to the source IP address and port from which the request originated. |
| RFC 3582 |

IPsec Configuration Policy Information Model
|
|
Summary Publication date: Aug 2003 This document presents an object-oriented information model of IP Security (IPsec) policy designed to facilitate agreement about the content and semantics of IPsec policy, and enable derivations of task-specific representations of IPsec policy such as storage schema, distribution representations, and policy specification languages used to configure IPsec-enabled endpoints. The information model described in this document models the configuration parameters defined by IPSec. The information model also covers the parameters found by the Internet Key Exchange protocol (IKE). Other key exchange protocols could easily be added to the information model by a simple extension. Further extensions can further be added easily due to the object-oriented nature of the model. This information model is based upon the core policy classes as defined in the Policy Core Information Model (PCIM) and in the Policy Core Information Model Extensions (PCIMe). |
| RFC 3586 |
