Hi All,
The following is a revised charter for CCAMP WG. It has been reviewed
by the IESG, and is now undergoing external review. Note that as has
been mentioned before, CCAMP is moving to the Routing Area.
Please send your comments to this list.

Description of Working Group:
Organizational Overview
The CCAMP working group coordinates the work within the IETF defining
a common control plane and a separate common measurement plane for
physical path and core tunneling technologies of Internet and telecom
service providers (ISPs and SPs), e.g. O-O and O-E-O optical
switches, ATM and Frame Relay switches, MPLS, GRE, in cooperation
with the MPLS WG. In this context, measurement refers to the
acquisition and distribution of attributes relevant to the setting up
of tunnels and paths.
CCAMP WG work scope includes:
- Definition of protocol-independent metrics and parameters
(measurement attributes) for describing links and paths that are
required for routing and signaling. These will be developed in
conjunction with requests and requirements from other WGs (e.g.
TEWG) to insure overall usefulness.
- Definition of protocol(s) and extensions to them required for
link and path attribute measurement. Link Management Protocol (LMP)
is included here.
- Functional specification of extensions for routing (OSPF, ISIS) and
signalling (RSVP-TE) required for path establishment. Protocol formats
and procedures that embody these extensions will be done jointly with
the WGs supervising those protocols.
- Definition of the mechanisms required to determine the route and
properties of an established path (tunnel tracing).
- Definition of MIB modules relevant to the protocols and extensions
specified within the WG.
CCAMP WG currently works on the following tasks:
- Define how the properties of network resources gathered by a
measurement protocol can be distributed in existing routing
protocols, such as OSPF and IS-IS. CCAMP defines the generic
description of the properties and how they are distributed in OSPF.
The specifics of distribution within IS-IS are being addressed in
the ISIS WG.
- Define signaling and routing mechanisms to make possible the creation
of paths that span multiple IGP areas, multiple ASes, and multiple
providers, including techniques for crankback.
- Define abstract link and path properties needed for link and path
protection. Specify signalling mechanisms for path protection,
diverse routing and fast path restoration. Ensure that multi-layer
path protection and restoration functions are achievable using the
defined signalling, routing, and measurement protocols, either
separately or in combination.
- Identify requirements for signaling and routing for ASON not currently
met; based on these, define mechanisms to address these requirements.
- Define a protocol that can determine the actual route and other
properties of paths set up by CCAMP signaling protocols, as well
as other types of tunnels (tunnel tracing).
In doing this work, the WG will work closely with at least the following
other WGs: TEWG, MPLS, ISIS, OSPF. The WG will also cooperate with
ITU-T.
Goals and Milestones:
