To improve scalability of Generalized Multi-Protocol Label Switching (GMPLS) it may be useful to aggregate Label Switched Paths (LSPs) by creating a hierarchy of such LSPs. A way to create such a hierarchy is by (a) a Label Switching Router (LSR) creating a Traffic Engineering Label Switched Path (TE LSP), (b) the LSR forming a forwarding adjacency (FA) out of that LSP (by advertising this LSP as …
Intermediate System to Intermediate System (IS-IS) Extensions in Support of Generalized Multi-Protocol Label Switching (GMPLS)
This document specifies encoding of extensions to the IS-IS routing protocol in support of Generalized Multi-Protocol Label Switching (GMPLS). This memo provides information for the Internet community.
For scalability purposes, multiple data links can be combined to form a single traffic engineering (TE) link. Furthermore, the management of TE links is not restricted to in-band messaging, but instead can be done using out-of-band techniques. This document specifies a link management protocol (LMP) that runs between a pair of nodes and is used to manage TE links. Specifically, LMP will be used to…

For the purpose of Generalized Multi-Protocol Label Switching (GMPLS) signaling, in certain cases a combination of <link identifier, label> is not sufficient to unambiguously identify the appropriate resource used by a Label Switched Path (LSP). Such cases are handled by using the link bundling construct, which is described in this document. This document updates the interface identification TLVs,…
A Uniform Resource Name (URN) Namespace for Federated Content

Procedures for Renumbering an IPv6 Network without a Flag Day
This document describes a procedure that can be used to renumber a network from one prefix to another. It uses IPv6's intrinsic ability to assign multiple addresses to a network interface to provide continuity of network service through a "make-before-break" transition, as well as addresses naming and configuration management issues. It also uses other IPv6 features to minimize the effort and time…
Default Router Preferences and More-Specific Routes
This document describes an optional extension to Router Advertisement messages for communicating default router preferences and more-specific routes from routers to hosts. This improves the ability of hosts to pick an appropriate router, especially when the host is multi-homed and the routers are on different links. The preference values and specific routes advertised to hosts require administrati…
Framework for Supporting Emergency Telecommunications Service (ETS) in IP Telephony
This document presents a framework for supporting authorized, emergency-related communication within the context of IP telephony. We present a series of objectives that reflect a general view of how authorized emergency service, in line with the Emergency Telecommunications Service (ETS), should be realized within today's IP architecture and service models. From these objectives, we present a corr…
Requirements for End-to-Middle Security for the Session Initiation Protocol (SIP)
A Session Initiation Protocol (SIP) User Agent (UA) does not always trust all intermediaries in its request path to inspect its message bodies and/or headers contained in its message. The UA might want to protect the message bodies and/or headers from intermediaries, except those that provide services based on its content. This situation requires a mechanism called "end-to-middle security" to secu…
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets.

National and Local Characters for DNS Top Level Domain (TLD) Names
In the context of work on internationalizing the Domain Name System (DNS), there have been extensive discussions about "multilingual" or "internationalized" top level domain names (TLDs), especially for countries whose predominant language is not written in a Roman-based script. This document reviews some of the motivations for such domains, several suggestions that have been made to provide neede…

Removing a Restriction on the use of MPLS Explicit NULL
The label stack encoding for Multi-protocol Label Switching (MPLS) defines a reserved label value known as "IPv4 Explicit NULL" and a reserved label value known as "IPv6 Explicit NULL". Previously, these labels were only legal when they occurred at the bottom of the MPLS label stack. This restriction is now removed, so that these label values may legally occur anywhere in the stack. This document …
