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, TDM Switches, 

Ethernet Switches, ATM and Frame Relay switches, IP encapsulation 

tunneling technologies, and MPLS 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.



- Work on traffic-engineering GMPLS mechanisms and protocol 

extensions to support source-controlled and explicitly-routed Ethernet 

data paths for Ethernet data planes that are already approved by an 

SDO with responsibility for the Ethernet data plane. It is expected that


the primary SDO in this case is the IEEE. Note that the specification 

or modification of Ethernet data planes is out of scope. 


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 and the IEEE 802.1.
