    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 to
    ensure 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 and other OAM techniques 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 and extensions to allow path
    and tunnel setup and maintenance across multiple domains, where a
    domain may be an IGP area, an Autonomous System, or any other region
    of topological visibility. To this end, work cooperatively with the
    PCE and MPLS WGs.

    - 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 which requirements for signaling and routing for ASON are
    not currently met by protocols defined in CCAMP; based on these,
    define mechanisms to address these requirements.

    - Document issues and strategies for the migration of MPLS-based
    deployments to GMPLS. Based on the outcome, identify protocol
    machinery that implementations may have to change to ease the
    migration from MPLS to GMPLS.

    In doing this work, the WG will work closely with at least the
    following other WGs: MPLS, ISIS, OSPF, IDR, L1VPN and PCE. The
    WG will also cooperate with the ITU-T.
