3493 Gilligan Mar 2003 Basic Socket Interface
Extensions for IPv6
The de facto standard Application Program Interface (API) for TCP/IP
applications is the "sockets" interface. Although this API was
developed for Unix in the early 1980s it has also been implemented on a
wide variety of non-Unix systems. TCP/IP applications written using the
sockets API have in the past enjoyed a high degree of portability and we
would like the same portability with IPv6 applications. But changes are
required to the sockets API to support IPv6 and this memo describes
these changes. These include a new socket address structure to carry
IPv6 addresses, new address conversion functions, and some new socket
options. These extensions are designed to provide access to the basic
IPv6 features required by TCP and UDP applications, including
multicasting, while introducing a minimum of change into the system and
providing complete compatibility for existing IPv4 applications.
Additional extensions for advanced IPv6 features (raw sockets and access
to the IPv6 extension headers) are defined in another document. This
memo provides information for the Internet community.

3492 Costello Mar 2003 Punycode: A Bootstring
encoding of Unicode for
Internationalized Domain Names
in Applications (IDNA)
Punycode is a simple and efficient transfer encoding syntax designed for
use with Internationalized Domain Names in Applications (IDNA). It
uniquely and reversibly transforms a Unicode string into an ASCII
string. ASCII characters in the Unicode string are represented
literally, and non-ASCII characters are represented by ASCII characters
that are allowed in host name labels (letters, digits, and hyphens).
This document defines a general algorithm called Bootstring that allows
a string of basic code points to uniquely represent any string of code
points drawn from a larger set. Punycode is an instance of Bootstring
that uses particular parameter values specified by this document,
appropriate for IDNA. [STANDARDS TRACK]
3491 Hoffman Mar 2003 Nameprep: A Stringprep Profile
for Internationalized Domain
Names (IDN)
This document describes how to prepare internationalized domain name
(IDN) labels in order to increase the likelihood that name input and
name comparison work in ways that make sense for typical users
throughout the world. This profile of the stringprep protocol is used
as part of a suite of on-the-wire protocols for internationalizing the
Domain Name System (DNS). [STANDARDS TRACK]
3490 Faltstrom Mar 2003 Internationalizing Domain
Names in Applications (IDNA)
Until now, there has been no standard method for domain names to use
characters outside the ASCII repertoire. This document defines
internationalized domain names (IDNs) and a mechanism called
Internationalizing Domain Names in Applications (IDNA) for handling them
in a standard fashion. IDNs use characters drawn from a large
repertoire (Unicode), but IDNA allows the non-ASCII characters to be
represented using only the ASCII characters already allowed in so-called
host names today. This backward-compatible representation is required
in existing protocols like DNS, so that IDNs can be introduced with no
changes to the existing infrastructure. IDNA is only meant for
processing domain names, not free text. [STANDARDS TRACK]

3489 Rosenberg Mar 2003 STUN - Simple Traversal of
User Datagram Protocol (UDP)
Through Network Address
Translators (NATs)
Simple Traversal of User Datagram Protocol (UDP) Through Network Address
Translators (NATs) (STUN) is a lightweight protocol that allows
applications to discover the presence and types of NATs and firewalls
between them and the public Internet. It also provides the ability for
applications to determine the public Internet Protocol (IP) addresses
allocated to them by the NAT. STUN works with many existing NATs, and
does not require any special behavior from them. As a result, it allows
a wide variety of applications to work through existing NAT
infrastructure. [STANDARDS TRACK]
3488 Wu Feb 2003 Cisco Systems Router-port
Group Management Protocol
(RGMP)
This document describes the Router-port Group Management Protocol
(RGMP). This protocol was developed by Cisco Systems and is used
between multicast routers and switches to restrict multicast packet
forwarding in switches to those routers where the packets may be needed.
RGMP is designed for backbone switched networks where multiple, high
speed routers are interconnected. This memo provides information for
the Internet community.

3485 Garcia-Martin Feb 2003 The Session Initiation
Protocol (SIP) and Session
Description Protocol
(SDP) Static Dictionary for
Signaling Compression
(SigComp)
The Session Initiation Protocol (SIP) is a text-based protocol for
initiating and managing communication sessions. The protocol can be
compressed by using Signaling Compression (SigComp). Similarly, the
Session Description Protocol (SDP) is a text-based protocol intended for
describing multimedia sessions for the purposes of session announcement,
session invitation, and other forms of multimedia session initiation.
This memo defines the SIP/SDP-specific static dictionary that SigComp
may use in order to achieve higher efficiency. The dictionary is
compression algorithm independent. [STANDARDS TRACK]
3484 Draves Feb 2003 Default Address Selection for
Internet Protocol version 6
(IPv6)
This document describes two algorithms, for source address selection and
for destination address selection. The algorithms specify default
behavior for all Internet Protocol version 6 (IPv6) implementations.
They do not override choices made by applications or upper-layer
protocols, nor do they preclude the development of more advanced
mechanisms for address selection. The two algorithms share a common
context, including an optional mechanism for allowing administrators to
provide policy that can override the default behavior. In dual stack
implementations, the destination address selection algorithm can
consider both IPv4 and IPv6 addresses - depending on the available
source addresses, the algorithm might prefer IPv6 addresses over IPv4
addresses, or vice-versa.
All IPv6 nodes, including both hosts and routers, must implement default
address selection as defined in this specification. [STANDARDS TRACK]

3482 Foster Feb 2003 Number Portability in the
Global Switched Telephone
Network (GSTN): An Overview
This document provides an overview of E.164 telephone number portability
(NP) in the Global Switched Telephone Network (GSTN).
NP is a regulatory imperative seeking to liberalize local telephony
service competition, by enabling end-users to retain telephone numbers
while changing service providers. NP changes the fundamental nature of
a dialed E.164 number from a hierarchical physical routing address to a
virtual address, thereby requiring the transparent translation of the
later to the former. In addition, there are various regulatory
constraints that establish relevant parameters for NP implementation,
most of which are not network technology specific. Consequently, the
implementation of NP behavior consistent with applicable regulatory
constraints, as well as the need for interoperation with the existing
GSTN NP implementations, are relevant topics for numerous areas of IP
telephony works-in-progress with the IETF. This memo provides
information for the Internet community.

3481 Inamura, Ed. Feb 2003 TCP over Second (2.5G)
and Third (3G) Generation
Wireless Networks
This document describes a profile for optimizing TCP to adapt so that it
handles paths including second (2.5G) and third (3G) generation wireless
networks. It describes the relevant characteristics of 2.5G and 3G
networks, and specific features of example deployments of such networks.
It then recommends TCP algorithm choices for nodes known to be starting
or ending on such paths, and it also discusses open issues. The
configuration options recommended in this document are commonly found in
modern TCP stacks, and are widely available standards-track mechanisms
that the community considers safe for use on the general Internet. This
document specifies an Internet Best Current Practices for the Internet
Community, and requests discussion and suggestions for improvements.
3480 Kompella Feb 2003 Signalling Unnumbered Links in
CR-LDP (Constraint-Routing
Label Distribution Protocol)
Current signalling used by Multi-Protocol Label Switching Traffic
Engineering (MPLS TE) does not provide support for unnumbered links.
This document defines procedures and extensions to Constraint-Routing
Label Distribution Protocol (CR-LDP), one of the MPLS TE signalling
protocols that are needed in order to support unnumbered links.
[STANDARDS TRACK]
3479 Farrel, Ed. Feb 2003 Fault Tolerance for the Label
Distribution Protocol (LDP)
Multiprotocol Label Switching (MPLS) systems will be used in core
networks where system downtime must be kept to an absolute minimum.
Many MPLS Label Switching Routers (LSRs) may, therefore, exploit Fault
Tolerant (FT) hardware or software to provide high availability of the
core networks.
The details of how FT is achieved for the various components of an FT
LSR, including Label Distribution Protocol (LDP), the switching hardware
and TCP, are implementation specific. This document identifies issues
in the LDP specification in RFC 3036, "LDP Specification", that make it
difficult to implement an FT LSR using the current LDP protocols, and
defines enhancements to the LDP specification to ease such FT LSR
implementations.
Ginoza Informational [Page 8]
RFC 3499 Summary of 3400-3499 December 2003
The issues and extensions described here are equally applicable to RFC
3212, "Constraint-Based LSP Setup Using LDP" (CR-LDP). [STANDARDS

3478 Leelanivas Feb 2003 Graceful Restart Mechanism for
Label Distribution Protocol
This document describes a mechanism that helps to minimize the negative
effects on MPLS traffic caused by Label Switching Router's (LSR's)
control plane restart, specifically by the restart of its Label
Distribution Protocol (LDP) component, on LSRs that are capable of
preserving the MPLS forwarding component across the restart.
The mechanism described in this document is applicable to all LSRs, both
those with the ability to preserve forwarding state during LDP restart
and those without (although the latter needs to implement only a subset
of the mechanism described in this document). Supporting (a subset of)
the mechanism described here by the LSRs that can not preserve their
MPLS forwarding state across the restart would not reduce the negative
impact on MPLS traffic caused by their control plane restart, but it
would minimize the impact if their neighbor(s) are capable of preserving
the forwarding state across the restart of their control plane and
implement the mechanism described here.
The mechanism makes minimalistic assumptions on what has to be preserved
across restart - the mechanism assumes that only the actual MPLS
forwarding state has to be preserved; the mechanism does not require any
of the LDP-related states to be preserved across the restart.
The procedures described in this document apply to downstream
unsolicited label distribution. Extending these procedures to
downstream on demand label distribution is for further study.

Constraint-Based LSP setup
using LDP (CR-LDP) Extensions
for Automatic Switched Optical
Network (ASON)
Automatic Switched Optical Network (ASON) is an architecture, specified
by ITU-T Study Group 15, for the introduction of a control plane for
optical networks. The ASON architecture specifies a set of reference
points that defines the relationship between the ASON architectural
entities. Signaling over interfaces defined in those reference points
can make use of protocols that are defined by the IETF in the context of
Generalized Multi-Protocol Label Switching (GMPLS) work. This document
describes Constraint-Based LSP setup using LDP (CR-LDP) extensions for
signaling over the interfaces defined in the ASON reference points. The
purpose of the document is to request that the IANA assigns code points
necessary for the CR-LDP extensions. The protocol specifications for
the use of the CR-LDP extensions are found in ITU-T documents. This
memo provides information for the Internet community.

3470 Hollenbeck Jan 2003 Guidelines for the Use
of Extensible Markup
Language (XML)
within IETF Protocols
The Extensible Markup Language (XML) is a framework for structuring
data. While it evolved from Standard Generalized Markup Language (SGML)
-- a markup language primarily focused on structuring documents -- XML
has evolved to be a widely-used mechanism for representing structured
data.
Ginoza Informational [Page 12]
RFC 3499 Summary of 3400-3499 December 2003
There are a wide variety of Internet protocols being developed; many
have need for a representation for structured data relevant to their
application. There has been much interest in the use of XML as a

3469 Sharma, Ed. Feb 2003 Framework for Multi-Protocol
Label Switching (MPLS)-based
Recovery
Multi-protocol label switching (MPLS) integrates the label swapping
forwarding paradigm with network layer routing. To deliver reliable
service, MPLS requires a set of procedures to provide protection of the
traffic carried on different paths. This requires that the label
switching routers (LSRs) support fault detection, fault notification,
and fault recovery mechanisms, and that MPLS signaling support the
configuration of recovery. With these objectives in mind, this document
specifies a framework for MPLS based recovery. Restart issues are not
included in this framework. This memo provides information for the
Internet community.

3465 Allman Feb 2003 TCP Congestion Control with
Appropriate Byte Counting
(ABC)
This document proposes a small modification to the way TCP increases its
congestion window. Rather than the traditional method of increasing the
congestion window by a constant amount for each arriving acknowledgment,
the document suggests basing the increase on the number of previously
unacknowledged bytes each ACK covers. This change improves the
performance of TCP, as well as closes a security hole TCP receivers can
use to induce the sender into increasing the sending rate too rapidly.
This memo defines an Experimental Protocol for the Internet community.

3464 Moore Jan 2003 An Extensible Message Format
for Delivery Status
Notifications
This memo defines a Multipurpose Internet Mail Extensions (MIME)
content-type that may be used by a message transfer agent (MTA) or
electronic mail gateway to report the result of an attempt to deliver a
message to one or more recipients. This content-type is intended as a
machine-processable replacement for the various types of delivery status
notifications currently used in Internet electronic mail.
Because many messages are sent between the Internet and other messaging
systems (such as X.400 or the so-called "Local Area Network (LAN)-based"
systems), the Delivery Status Notification (DSN) protocol is designed to
be useful in a multi-protocol messaging environment. To this end, the
protocol described in this memo provides for the carriage of "foreign"
addresses and error codes, in addition to those normally used in
Internet mail. Additional attributes may also be defined to support
"tunneling" of foreign notifications through Internet mail. [STANDARDS

Status Notifications (DSNs) should be generated under certain
conditions, (b) whether such notifications should return the contents of
the message, and (c) additional information, to be returned with a DSN,

sent. [STANDARDS TRACK]
3460 Moore Jan 2003 Policy Core Information Model
(PCIM) Extensions
This document specifies a number of changes to the Policy Core
Information Model (PCIM, RFC 3060). Two types of changes are included.
First, several completely new elements are introduced, for example,
classes for header filtering, that extend PCIM into areas that it did
not previously cover. Second, there are cases where elements of PCIM
(for example, policy rule priorities) are deprecated, and replacement
elements are defined (in this case, priorities tied to associations that
refer to policy rules). Both types of changes are done in such a way
that, to the extent possible, interoperability with implementations of
the original PCIM model is preserved. This document updates RFC 3060.

3459 Burger Jan 2003 Critical Content Multi-purpose
Internet Mail Extensions
(MIME) Parameter
This document describes the use of a mechanism for identifying body
parts that a sender deems critical in a multi-part Internet mail
message. The mechanism described is a parameter to Content-Disposition,
as described by RFC 3204.
Ginoza Informational [Page 16]
RFC 3499 Summary of 3400-3499 December 2003
By knowing what parts of a message the sender deems critical, a content
gateway can intelligently handle multi-part messages when providing
gateway services to systems of lesser capability. Critical content can
help a content gateway to decide what parts to forward. It can indicate
how hard a gateway should try to deliver a body part. It can help the
gateway to pick body parts that are safe to silently delete when a
system of lesser capability receives a message. In addition, critical
content can help the gateway chose the notification strategy for the
receiving system. Likewise, if the sender expects the destination to do
some processing on a body part, critical content allows the sender to
mark body parts that the receiver must process. [STANDARDS TRACK]
3458 Burger Jan 2003 Message Context for Internet
Mail
This memo describes a new RFC 2822 message header, "Message-Context".
This header provides information about the context and presentation
characteristics of a message.

optimally present the message. [STANDARDS TRACK]
3457 Kelly Jan 2003 Requirements for IPsec Remote
Access Scenarios
IPsec offers much promise as a secure remote access mechanism. However,
there are a number of differing remote access scenarios, each having
some shared and some unique requirements. A thorough understanding of
these requirements is necessary in order to effectively evaluate the
suitability of a specific set of mechanisms for any particular remote
access scenario. This document enumerates the requirements for a number
of common remote access scenarios. This memo provides information for

3456 Patel Jan 2003 Dynamic Host Configuration
Protocol (DHCPv4)
Configuration of IPsec Tunnel
Mode
This memo explores the requirements for host configuration in IPsec
tunnel mode, and describes how the Dynamic Host Configuration Protocol
(DHCPv4) may be leveraged for configuration. In many remote access
scenarios, a mechanism for making the remote host appear to be present
on the local corporate network is quite useful. This may be
accomplished by assigning the host a "virtual" address from the
corporate network, and then tunneling traffic via IPsec from the host's
ISP-assigned address to the corporate security gateway. In IPv4, DHCP
provides for such remote host configuration. [STANDARDS TRACK]

3453 Luby Dec 2002 The Use of Forward Error
Correction (FEC) in Reliable
Multicast
This memo describes the use of Forward Error Correction (FEC) codes to
efficiently provide and/or augment reliability for one-to-many reliable
data transport using IP multicast. One of the key properties of FEC
codes in this context is the ability to use the same packets containing
FEC data to simultaneously repair different packet loss patterns at
multiple receivers. Different classes of FEC codes and some of their
basic properties are described and terminology relevant to implementing
FEC in a reliable multicast protocol is introduced. Examples are
provided of possible abstract formats for packets carrying FEC. This
memo provides information for the Internet community.
3452 Luby Dec 2002 Forward Error Correction (FEC)
Building Block
This document generally describes how to use Forward Error Correction
(FEC) codes to efficiently provide and/or augment reliability for data
transport. The primary focus of this document is the application of FEC
codes to one-to-many reliable data transport using IP multicast. This
document describes what information is needed to identify a specific FEC
code, what information needs to be communicated out-of-band to use the
FEC code, and what information is needed in data packets to identify the
encoding symbols they carry. The procedures for specifying FEC codes
and registering them with the Internet Assigned Numbers Authority (IANA)
are also described. This document should be read in conjunction with
and uses the terminology of the companion document titled, "The Use of
Forward Error Correction (FEC) in Reliable Multicast". This memo
defines an Experimental Protocol for the Internet community.
3451 Luby Dec 2002 Layered Coding Transport (LCT)

Layered Coding Transport (LCT) provides transport level support for
reliable content delivery and stream delivery protocols. LCT is
specifically designed to support protocols using IP multicast, but also
provides support to protocols that use unicast. LCT is compatible with
congestion control that provides multiple rate delivery to receivers and
is also compatible with coding techniques that provide reliable delivery
of content. This memo defines an Experimental Protocol for the Internet

3449 Balakrishnan Dec 2002 TCP Performance Implications
of Network Path Asymmetry
This document describes TCP performance problems that arise because of
asymmetric effects. These problems arise in several access networks,
including bandwidth-asymmetric networks and packet radio subnetworks,
for different underlying reasons. However, the end result on TCP
performance is the same in both cases: performance often degrades
significantly because of imperfection and variability in the ACK
feedback from the receiver to the sender.
The document details several mitigations to these effects, which have
either been proposed or evaluated in the literature, or are currently
deployed in networks. These solutions use a combination of local link-
layer techniques, subnetwork, and end-to-end mechanisms, consisting of:
(i) techniques to manage the channel used for the upstream bottleneck
link carrying the ACKs, typically using header compression or reducing
the frequency of TCP ACKs, (ii) techniques to handle this reduced ACK
frequency to retain the TCP sender's acknowledgment-triggered self-
clocking and (iii) techniques to schedule the data and ACK packets in
the reverse direction to improve performance in the presence of two-way
traffic. Each technique is described, together with known issues, and
recommendations for use. A summary of the recommendations is provided
at the end of the document. This document specifies an Internet Best
Current Practices for the Internet Community, and requests discussion

This document specifies TCP-Friendly Rate Control (TFRC). TFRC is a
congestion control mechanism for unicast flows operating in a best-
effort Internet environment. It is reasonably fair when competing for
bandwidth with TCP flows, but has a much lower variation of throughput

3437 Palter Dec 2002 Layer-Two Tunneling Protocol
Extensions for PPP Link
Control Protocol Negotiation
This document defines extensions to the Layer Two Tunneling Protocol
(L2TP) for enhanced support of link-specific Point to Point Protocol
(PPP) options. PPP endpoints typically have direct access to the common
physical media connecting them and thus have detailed knowledge about
the media that is in use. When the L2TP is used, the two PPP peers are
no longer directly connected over the same physical media. Instead,
L2TP inserts a virtual connection over some or all of the PPP connection
by tunneling PPP frames over a packet switched network such as IP.
Under some conditions, an L2TP endpoint may need to negotiate PPP Link
Control Protocol (LCP) options at a location which may not have access
to all of the media information necessary for proper participation in
the LCP negotiation. This document provides a mechanism for
communicating desired LCP options between L2TP endpoints in advance of
PPP LCP negotiation at the far end of an L2TP tunnel, as well as a
mechanism for communicating the negotiated LCP options back to where the
native PPP link resides. [STANDARDS TRACK]

3435 Andreasen Jan 03 Media Gateway Control Protocol
(MGCP) Version 1.0
This document describes an application programming interface and a
corresponding protocol (MGCP) which is used between elements of a
decomposed multimedia gateway. The decomposed multimedia gateway
consists of a Call Agent, which contains the call control
"intelligence", and a media gateway which contains the media functions,
e.g., conversion from TDM voice to Voice over IP.
Media gateways contain endpoints on which the Call Agent can create,
modify and delete connections in order to establish and control media
sessions with other multimedia endpoints. Also, the Call Agent can
instruct the endpoints to detect certain events and generate signals.
The endpoints automatically communicate changes in service state to the
Call Agent. Furthermore, the Call Agent can audit endpoints as well as
the connections on endpoints.
The basic and general MGCP protocol is defined in this document, however
most media gateways will need to implement one or more MGCP packages,
which define extensions to the protocol suitable for use with specific
types of media gateways. Such packages are defined in separate
documents. This memo provides information for the Internet community.

interfaces. This document adds the zero-byte operation for ROHC
Bidirectional Reliable mode (R-mode) to the ones specified for
Unidirectional (U-mode) and Bidirectional Optimistic (O-mode) modes of
header compression in RFC 3242. [STANDARDS TRACK]
3407 Andreasen Oct 2002 Session Description Protocol
(SDP) Simple Capability
Declaration
This document defines a set of Session Description Protocol (SDP)
attributes that enables SDP to provide a minimal and backwards
compatible capability declaration mechanism. Such capability
declarations can be used as input to a subsequent session negotiation,
which is done by means outside the scope of this document. This
provides a simple and limited solution to the general capability
negotiation problem being addressed by the next generation of SDP, also
known as SDPng. [STANDARDS TRACK]

3406 Daigle Oct 2002 Uniform Resource Names (URN)
Namespace Definition
Mechanisms
This document lays out general definitions of and mechanisms for
establishing Uniform Resource Names (URN) "namespaces". The URN WG has
defined a syntax for URNs in RFC 2141, as well as some proposed
mechanisms for their resolution and use in Internet applications in RFC
3401 and RFC 3405. The whole rests on the concept of individual
"namespaces" within the URN structure. Apart from proof-of-concept
namespaces, the use of existing identifiers in URNs has been discussed
in RFC 2288. This document specifies an Internet Best Current Practices
for the Internet Community, and requests discussion and suggestions for
improvements.
3405 Mealling Oct 2002 Dynamic Delegation Discovery
System (DDDS) Part Five:
URI.ARPA Assignment Procedures
This document is fifth in a series that is completely specified in
"Dynamic Delegation Discovery System (DDDS) Part One: The Comprehensive
DDDS" (RFC 3401). It is very important to note that it is impossible to
read and understand any document in this series without reading the
others. This document specifies an Internet Best Current Practices for
the Internet Community, and requests discussion and suggestions for
improvements.
3404 Mealling Oct 2002 Dynamic Delegation Discovery
System (DDDS) Part Four: The
Uniform Resource Identifiers
(URI) Resolution Application
This document describes a specification for taking Uniform Resource
Identifiers (URI) and locating an authoritative server for information
about that URI. The method used to locate that authoritative server is
the Dynamic Delegation Discovery System.
This document is part of a series that is specified in "Dynamic
Delegation Discovery System (DDDS) Part One: The Comprehensive DDDS"
(RFC 3401). It is very important to note that it is impossible to read
and understand any document in this series without reading the others.

3403 Mealling Oct 2002 Dynamic Delegation Discovery
System (DDDS) Part Three: The
Domain Name System (DNS)
Database
This document describes a Dynamic Delegation Discovery System (DDDS)
Database using the Domain Name System (DNS) as a distributed database of
Rules. The Keys are domain-names and the Rules are encoded using the
Naming Authority Pointer (NAPTR) Resource Record (RR).
Since this document obsoletes RFC 2915, it is the official specification
for the NAPTR DNS Resource Record. It is also part of a series that is
completely specified in "Dynamic Delegation Discovery System (DDDS) Part
One: The Comprehensive DDDS" (RFC 3401). It is very important to note
that it is impossible to read and understand any document in this series
without reading the others. [STANDARDS TRACK]
3402 Mealling Oct 2002 Dynamic Delegation Discovery
System (DDDS) Part Two: The
Algorithm
This document describes the Dynamic Delegation Discovery System (DDDS)
algorithm for applying dynamically retrieved string transformation rules
to an application-unique string. Well-formed transformation rules will
reflect the delegation of management of information associated with the
string. This document is also part of a series that is completely
specified in "Dynamic Delegation Discovery System (DDDS) Part One: The
Comprehensive DDDS" (RFC 3401). It is very important to note that it is
impossible to read and understand any document in this series without
reading the others. [STANDARDS TRACK]
3401 Mealling Oct 2002 Dynamic Delegation Discovery
System (DDDS) Part One: The
Comprehensive DDDS
This document specifies the exact documents that make up the complete
Dynamic Delegation Discovery System (DDDS). DDDS is an abstract
algorithm for applying dynamically retrieved string transformation rules
to an application-unique string. This document along with RFC 3402, RFC
3403 and RFC 3404 obsolete RFC 2168 and RFC 2915, as well as updates RFC
2276. This memo provides information for the Internet community.
