New charter text (2 of 2) 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 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. Identify issues in GMPLS interoperation among various implementations, including those related to addressing, path computation and constraints. Document clarifications of the current specifications. Analyze the requirements and architecture for GMPLS multi-layer networks where a layer may be a technology layer or may indicate a client/server network relationship. Develop routing and signaling protocol extensions as necessary to satisfy the requirements. To this end, work cooperatively with the PCE WG. 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. 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). 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: TEWG, MPLS, ISIS, OSPF, IDR, L1VPN and PCE. The WG will also cooperate with the ITU-T. |
