 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 ISP
 and SP physical path and core tunneling technologies (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.
