The CCAMP working group coordinates the work within the IETF defining a common control plane and a separate common measurement plane for ISP and SP core tunneling technologies.
CCAMP WG tasks include:
- Define signalling protocols and measurement protocols such that they support multiple physical path and tunnel technologies (e.g. O-O and O-E-O optical switches, ATM and Frame Relay switches, MPLS, GRE) using input from technology-specific working groups such as MPLS, IPO, etc.
- Define signalling and measurement protocols that are independent of each other. This allows applications other than the signalling protocol to use the measurement protocol; it also allows the signalling protocol to use knowledge obtained by means other than the measurement protocol.
- Develop and define a set of protocol-independent metrics and parameters for describing links and paths that can be carried in protocols. These will be developed in conjunction with requests and requirements from other WGs (e.g., TEWG, PPVPN, etc.) to insure overall usefulness.
- Abstract link and path properties needed for link and path protection. Define 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 and measurement protocols, either separately or in combination.
- Define how the properties of network resources gathered by the measurement protocol can be distributed in existing routing protocols, such as OSPF and IS-IS.
- Define the relationship between layer 3 routing protocols and the common signalling protocol for establishing and maintaining paths.
- Using input from the TE working group, ensure that the signalling and measurement protocols provide both the information and the control functions adequate to support the traffic provisioning and engineering operations of service providers.
In doing this work, the WG will work closely with at least the following other WGs and constituencies: TEWG, PPVPN, IPO, MPLS, IPORPR, ISIS, OSPF, and GSMP.
