3298 Faynberg Aug 2002 Service in the Public Switched
Telephone Network/Intelligent Network (PSTN/IN) Requesting InTernet Service (SPIRITS) Protocol Requirements

This document describes the SPIRITS protocol requirements, based on the
architecture presented in RFC 3136. (SPIRITS stands for "Service in the
PSTN/IN Requesting InTernet Service".) The purpose of the protocol is
to support services that originate in the Public Switched Telephone
Network (PSTN) and necessitate the interactions between the PSTN and the
Internet. Similarly, such services are called SPIRITS services.
(Internet Call Waiting, Internet Caller-ID Delivery, and Internet Call
Forwarding are examples of SPIRIT services, but the protocol is to
define the building blocks from which many other services can be built.)
On the PSTN side, the SPIRITS services are initiated from the
Intelligent Network (IN) entities; the earlier IETF work on the
PSTN/Internet Interworking (PINT) resulted in the protocol (RFC 2848) in
support of the services initiated the other way around--from the
Internet to PSTN.

To this end, this document lists general requirements for the SPIRITS
protocol as well as those pertinent to IN, Wireless IN, and PINT
building blocks. The document also presents the SPIRITS WG consensus on
the choice of the SPIRITS signaling protocol. This memo provides
information for the Internet community.

This document specifies XML (Extensible Markup Language) digital
signature processing rules and syntax. [STANDARDS TRACK]

3274 Gutmann Jun 2002 Compressed Data Content Type
for Cryptographic Message Syntax (CMS)

This document defines a format for using compressed data as a
Cryptographic Message Syntax (CMS) content type. Compressing data
before transmission provides a number of advantages, including the
elimination of data redundancy which could help an attacker, speeding up
processing by reducing the amount of data to be processed by later steps
(such as signing or encryption), and reducing overall message size.
Although there have been proposals for adding compression at other
levels (for example at the MIME or SSL level), these don't address the
problem of compression of CMS content unless the compression is supplied
by an external means (for example by intermixing MIME and CMS).

3264 Rosenberg Jun 2002 An Offer/Answer Model with the
Session Description Protocol (SDP)

This document defines a mechanism by which two entities can make use of
the Session Description Protocol (SDP) to arrive at a common view of a
multimedia session between them. In the model, one participant offers
the other a description of the desired session from their perspective,
and the other participant answers with the desired session from their
perspective. This offer/answer model is most useful in unicast sessions
where information from both participants is needed for the complete view
of the session. The offer/answer model is used by protocols like the
Session Initiation Protocol (SIP). [STANDARDS TRACK]

3263 Rosenberg Jun 2002 Session Initiation Protocol
(SIP): Locating SIP Servers

The Session Initiation Protocol (SIP) uses DNS procedures to allow a
client to resolve a SIP Uniform Resource Identifier (URI) into the IP

3254 Alvestrand Apr 2002 Definitions for talking about
directories

When discussing systems for making information accessible through the
Internet in standardized ways, it may be useful if the people who are
discussing it have a common understanding of the terms they use. For
example, a reference to this document would give one the power to agree
that the DNS (Domain Name System) is a global lookup repository with
perimeter integrity and loose, converging consistency. On the other
hand, a LDAP (Lightweight Directory Access Protocol) directory server is
a local, centralized repository with both lookup and search capability.
This document discusses one group of such systems which is known under
the term, "directories". This memo provides information for the
Internet community.

3248 Armitage Mar 2002 A Delay Bound alternative
revision of RFC 2598

For historical interest, this document captures the EF Design Team's
proposed solution, preferred by the original authors of RFC 2598 but not
adopted by the working group in December 2000. The original definition
of EF was based on comparison of forwarding on an unloaded network.
This experimental Delay Bound (DB) PHB requires a bound on the delay of
packets due to other traffic in the network. At the Pittsburgh IETF
meeting in August 2000, the Differentiated Services working group faced
serious questions regarding RFC 2598 - the group's standards track
definition of the Expedited Forwarding (EF) Per Hop Behavior (PHB). An
'EF Design Team' volunteered to develop a re-expression of RFC 2598,
bearing in mind the issues raised in the DiffServ group. At the San
Diego IETF meeting in December 2000 the DiffServ working group decided
to pursue an alternative re-expression of the EF PHB. This memo
provides information for the Internet community.

3247 Charny Mar 2002 Supplemental Information for
the New Definition of the EF PHB (Expedited Forwarding Per-Hop Behavior)

This document was written during the process of clarification of RFC2598
"An Expedited Forwarding PHB" that led to the publication of revised
specification of EF "An Expedited Forwarding PHB". Its primary
motivation is providing additional explanation to the revised EF
definition and its properties. The document also provides additional
implementation examples and gives some guidance for computation of the
numerical parameters of the new definition for several well known
schedulers and router architectures. This memo provides information for
the Internet community.

3246 Davie Mar 2002 An Expedited Forwarding PHB
(Per-Hop Behavior)

This document defines a PHB (per-hop behavior) called Expedited

between a source host and destination host. This document establishes a
catalogue or taxonomy of middleboxes, cites previous and current IETF
work concerning middleboxes, and attempts to identify some preliminary
conclusions. It does not, however, claim to be definitive. This memo
provides information for the Internet community.

3233 Hoffman Feb 2002 Defining the IETF

This document gives a more concrete definition of "the IETF" as it
understood today. Many RFCs refer to "the IETF". Many important IETF
documents speak of the IETF as if it were an already-defined entity.
However, no IETF document correctly defines what the IETF is. This
document specifies an Internet Best Current Practices for the Internet
Community, and requests discussion and suggestions for improvements.

3232 Reynolds Jan 2002 Assigned Numbers: RFC 1700 is
Replaced by an On-line Database

This memo obsoletes RFC 1700 (STD 2) "Assigned Numbers", which contained
an October 1994 snapshot of assigned Internet protocol parameters. This
memo provides information for the Internet community.

3231 Levi Jan 2002 Definitions of Managed Objects
for Scheduling Management Operations

This memo defines a portion of the Management Information Base (MIB) for
use with network management protocols in the Internet community. In
particular, it describes a set of managed objects that are used to
schedule management operations periodically or at specified dates and
times. [STANDARDS TRACK]

3230 Mogul Jan 2002 Instance Digests in HTTP

HTTP/1.1 defines a Content-MD5 header that allows a server to include a
digest of the response body. However, this is specifically defined to
cover the body of the actual message, not the contents of the full file
(which might be quite different, if the response is a Content-Range, or
uses a delta encoding). Also, the Content-MD5 is limited to one
specific digest algorithm; other algorithms, such as SHA-1 (Secure Hash
Standard), may be more appropriate in some circumstances. Finally,
HTTP/1.1 provides no explicit mechanism by which a client may request a
digest. This document proposes HTTP extensions that solve these
problems. [STANDARDS TRACK]

3229 Mogul Jan 2002 Delta encoding in HTTP

This document describes how delta encoding can be supported as a
compatible extension to HTTP/1.1. [STANDARDS TRACK]

3228 Fenner Feb 2002 IANA Considerations for IPv4
Internet Group Management Protocol (IGMP)

This memo requests that the IANA create a registry for fields in the
IGMP (Internet Group Management Protocol) protocol header, and provides
guidance for the IANA to use in assigning parameters for those fields.
This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements.

3227 Brezinski Feb 2002 Guidelines for Evidence
Collection and Archiving

A "security incident" as defined in the "Internet Security Glossary",
RFC 2828, is a security-relevant system event in which the system's
security policy is disobeyed or otherwise breached. The purpose of this
document is to provide System Administrators with guidelines on the
collection and archiving of evidence relevant to such a security
incident. This document specifies an Internet Best Current Practices
for the Internet Community, and requests discussion and suggestions for
improvements.

3226 Gudmundsson Dec 2001 DNSSEC and IPv6 A6 aware
server/resolver message size requirements

This document mandates support for EDNS0 (Extension Mechanisms for DNS)
in DNS entities claiming to support either DNS Security Extensions or A6
records. This requirement is necessary because these new features
increase the size of DNS messages. If EDNS0 is not supported fall back
to TCP will happen, having a detrimental impact on query latency and DNS
server load. This document updates RFC 2535 and RFC 2874, by adding new
requirements. [STANDARDS TRACK]

3225 Conrad Dec 2001 Indicating Resolver Support of
DNSSEC

In order to deploy DNSSEC (Domain Name System Security Extensions)
operationally, DNSSEC aware servers should only perform automatic
inclusion of DNSSEC RRs when there is an explicit indication that the
resolver can understand those RRs. This document proposes the use of a
bit in the EDNS0 header to provide that explicit indication and
describes the necessary protocol changes to implement that notification.

3224 Guttman Jan 2002 Vendor Extensions for Service
Location Protocol, Version 2

This document specifies how the features of the Service Location
Protocol, Version 2 allow for vendor extensibility safely, with no
possibility of collisions. The specification introduces a new SLPv2
extension: The Vendor Opaque Extension. While proprietary protocol
extensions are not encouraged by IETF standards, it is important that
they not hinder interoperability of compliant implementations when they
are undertaken. This document udpates RFC 2608, "The Service Location
Protocol." [STANDARDS TRACK]

3222 Trotter Dec 2001 Terminology for Forwarding
Information Base (FIB) based Router Performance

This document describes the terms to be used in a methodology that
determines the IP packet forwarding performance of IP routers as a
function of the forwarding information base installed within a router.
The forwarding performance of an IP router may be dependent upon or may
be linked to the composition and size of the forwarding information base
installed within a router. This memo provides information for the
Internet community.

3221 Huston Dec 2001 Commentary on Inter-Domain
Routing in the Internet

This document examines the various longer term trends visible within the
characteristics of the Internet's BGP table and identifies a number of
operational practices and protocol factors that contribute to these
trends. The potential impacts of these practices and protocol
properties on the scaling properties of the inter-domain routing space
are examined. This memo provides information for the Internet
community.

3220 Perkins Jan 2002 IP Mobility Support for IPv4

This document specifies protocol enhancements that allow transparent
routing of IP datagrams to mobile nodes in the Internet. Each mobile
node is always identified by its home address, regardless of its current
point of attachment to the Internet. While situated away from its home,
a mobile node is also associated with a care-of address, which provides
information about its current point of attachment to the Internet. The
protocol provides for registering the care-of address with a home agent.
The home agent sends datagrams destined for the mobile node through a
tunnel to the care-of address. After arriving at the end of the tunnel,
each datagram is then delivered to the mobile node. [STANDARDS TRACK]

3219 Rosenberg Jan 2002 Telephony Routing over IP
(TRIP)

This document presents the Telephony Routing over IP (TRIP). TRIP is a
policy driven inter-administrative domain protocol for advertising the
reachability of telephony destinations between location servers, and for
advertising attributes of the routes to those destinations. TRIP's
operation is independent of any signaling protocol, hence TRIP can serve
as the telephony routing protocol for any signaling protocol.

3215 Boscher Jan 2002 LDP State Machine

This document provides state machine tables for ATM (Asynchronous
Transfer Mode) switch LSRs. In the current LDP specification, there is
no state machine specified for processing LDP messages. We think that
defining a common state machine is very important for interoperability
between different LDP and CR-LDP implementations. This memo provides
information for the Internet community.

3214 Ash Jan 2002 LSP Modification Using CR-LDP

This document presents an approach to modify the bandwidth and possibly
other parameters of an established CR-LSP (Constraint-based Routed Label
Switched Paths) using CR-LDP (Constraint-based Routed Label Distribution
Protocol) without service interruption. [STANDARDS TRACK]

3213 Ash Jan 2002 Applicability Statement for
CR-LDP

This document discusses the applicability of Constraint-Based LSP Setup
using LDP. It discusses possible network applications, extensions to
Label Distribution Protocol (LDP) required to implement constraint-based
routing, guidelines for deployment and known limitations of the
protocol. This document is a prerequisite to advancing CR-LDP on the
standards track. This memo provides information for the Internet
community.

CMS

This document provides a method of encrypting data using user-supplied
passwords and, by extension, any form of variable-length keying material
which is not necessarily an algorithm-specific fixed-format key. The
Cryptographic Message Syntax data format does not currently contain any
provisions for password-based data encryption. [STANDARDS TRACK]

3210 Awduche Dec 2001 Applicability Statement for
Extensions to RSVP for LSP-Tunnels

This memo discusses the applicability of "Extensions to RSVP (Resource
ReSerVation Protocol) for LSP Tunnels". It highlights the protocol's
principles of operation and describes the network context for which it
was designed. Guidelines for deployment are offered and known protocol
limitations are indicated. This document is intended to accompany the
submission of "Extensions to RSVP for LSP Tunnels" onto the Internet
standards track. This memo provides information for the Internet
community.

3209 Awduche Dec 2001 RSVP-TE: Extensions to RSVP
for LSP Tunnels

This document describes the use of RSVP (Resource Reservation Protocol),
including all the necessary extensions, to establish label-switched
paths (LSPs) in MPLS (Multi-Protocol Label Switching). Since the flow
along an LSP is completely identified by the label applied at the
ingress node of the path, these paths may be treated as tunnels. A key
application of LSP tunnels is traffic engineering with MPLS as specified
in RFC 2702. [STANDARDS TRACK]

3208 Speakman Dec 2001 PGM Reliable Transport
Protocol Specification

Pragmatic General Multicast (PGM) is a reliable multicast transport
protocol for applications that require ordered or unordered, duplicate-
free, multicast data delivery from multiple sources to multiple
receivers. PGM guarantees that a receiver in the group either receives
all data packets from transmissions and repairs, or is able to detect
unrecoverable data packet loss. PGM is specifically intended as a
workable solution for multicast applications with basic reliability
requirements. Its central design goal is simplicity of operation with
due regard for scalability and network efficiency. This memo defines an
Experimental Protocol for the Internet community.

3207 Hoffman Feb 2002 SMTP Service Extension for
Secure SMTP over Transport Layer Security

This document describes an extension to the SMTP (Simple Mail Transfer
Protocol) service that allows an SMTP server and client to use TLS
(Transport Layer Security) to provide private, authenticated
communication over the Internet. This gives SMTP agents the ability to
protect some or all of their communications from eavesdroppers and
attackers. [STANDARDS TRACK]

3206 Gellens Feb 2002 The SYS and AUTH POP Response
