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 management objects (e.g. as part of MIB modules) and
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 Standards Development Organization (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.
- Work on GMPLS mechanisms and protocol extensions to support the
transport profile of MPLS (MPLS-TP) in cooperation with the MPLS,
L2VPN, and PWE3 Working Group and in coordination with the
requirements expressed jointly by the IETF and ITU-T.

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
Automatically Switched Optical Network (ASON) are not currently met
by protocols defined in CCAMP; based on these, define mechanisms to
address these requirements.

- Produce extensions to the CCAMP WG protocols and RFCs necessary
to create an MPLS Transport Profile (MPLS TP). The work on the
MPLS TP will be coordinated between the MPLS, L2VPN, PWE3, and CCAMP
working groups that are jointly chartered to do MPLS TP work.

In doing this work, the WG will work closely with at least the
following other WGs: MPLS, L2VPN, PWE3, ISIS, OSPF, IDR, L1VPN and PCE.
The WG will also cooperate with the ITU-T and the IEEE 802.1.
