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 and extensions to protocols for link and path attribute measurement. This includes the Link Management Protocol (LMP). - Functional specification of extensions for GMPLS-related routing (OSPF, ISIS) and signaling (RSVP-TE) protocols required for path establishment and maintenance. 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 control of 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 data paths for data planes that are already approved by a Standards Development Organization (SDO). Note that the specification or modification of data planes is out of scope of this working group. Example data planes include Wavelength Switched Optical Networks (WSON), Optical Transport Networks (OTN), Ethernet, and the MPLS data plane. - 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 (or by other means e.g. configured) can be distributed in existing routing protocols, such as OSPF and IS-IS. CCAMP will work with the WGs that supervise these protocols. The specifics of distribution within IS-IS are being addressed in the ISIS WG. Current work activities are focused in the areas of WSON and OTN. - 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 signaling mechanisms for path protection, diverse routing and fast path restoration. Ensure that multi-layer path protection and restoration functions are achievable using the defined signaling, routing, and measurement protocols, either separately or in combination. - Identify signaling and routing requirements for supporting protocol extensions in support of data plane technologies (e.g., WSON, OTN, MPLS-TP, and Ethernet) and network architectures (e.g. ITU-T's Automatically Switched Optical Network (ASON)) not currently met by protocols defined in CCAMP; based on these, define mechanisms to address these requirements. This activity will build on documents produced by the WG, including Informational, Standards Track and Experimental documents. - 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, and PCE. The WG will also cooperate with the ITU-T and the IEEE 802.1.
