Description of Working Group:
Note: this WG is one of a set of WGs that comprise the 'sub-IP'
pseudo-area that the IESG recently created. All of the sub-IP WGs are
temporarily being housed in the General Area until the IESG decides on
a final management structure for managing these groups. The Area
Directors for the following areas acting as a group will be the Area
Advisors: INT, OPS, RTG and TSV. The name(s) listed above under
"Technical Advisor(s)" are the the responsible Area Directors for the
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 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.
Goals and Milestones:
Jan 01 Post strawman WG goals and charter
Feb 01 Begin discussion of the framework and the requirement documents
for signalling and for measurement
Feb 01 Identify and document a limited set of candidate solutions for
signalling and for measurement. Among candidate control
solutions to be considered are the existing GMPLS drafts.
Mar 01 Build appropriate design teams
Apr 01 Submit Initial framework and requirement documents
May 01 Submit WG document defining path setup portions of common
control plane protocol
May 01 Submit WG document defining common measurement plane protocol
May 01 Submit revised charter and milestones to IESG for IESG
consideration of more detailed deliverables and determination
of usefulness of continuation of WG
