A modified charter has been submitted for the Common Control and Measurement Plane (ccamp) working group in the Routing Area of the IETF. The IESG has not made any determination as yet. The modified charter is provided below for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by October 29. +++ Common Control and Measurement Plane (ccamp) ============================================ Current Status: Active Working Group Chair(s): * Adrian Farrel <adrian@olddog.co.uk> * Deborah Brungard <dbrungard@att.com> Routing Area Director(s): * Ross Callon <rcallon@juniper.net> * David Ward <dward@cisco.com> Routing Area Advisor: * Ross Callon <rcallon@juniper.net> Technical Advisor(s): * Alex Zinin <zinin@psg.com> Mailing Lists: General Discussion: ccamp@ops.ietf.org To Subscribe: majordomo@ops.ietf.org In Body: subscribe ccamp Archive: https://ops.ietf.org/lists/ccamp 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.
