Charter Update Needed

• Current scope and work description need minor
  updates
• Milestones are out of sync with current work
• Aug 2008 - First version of Working Group draft
  providing Control Plane Framework for MPLS-TP
• Sep 2008 - Submit OSPF-TE/GMPLS MIB module for
  MIB doctor and IESG review
• Oct 2008 - First version of Working Group draft
  defining RSVP-TE extensions for MPLS-TP
• Dec 2008 - Submit GMPLS OAM Requirements I-D for
  IESG review
• Jan 2009 - Submit protocol extensions for GMPLS
  source-controlled and explicitly-routed
  Ethernet networks for IESG review
• Feb 2009 - Submit Protocol solutions for MLN/MRN
  I-D for IESG review
• Mar 2009 - Submit Control Plane Framework for
  MPLS-TP for IESG review
• Jun 2009 - Submit RSVP-TE extensions for MPLS-TP
  for IESG review
• Jun 2009 - Recharter or close Working Group
• Chairs have a baseline proposed update
• Need input from AD, WG
• Objective is to discuss today and on list
• Goal is a final update by the end of the year

Proposed changes Scope

• No major changes
• Minor wording changes to clarify scope
• Group focuses on GMPLS protocols
• Were data plane agnostic (which is defined
  outside of CCAMP/IETF)

4
Proposed changes Scope (cont.)

• Proposed language
• red delete, underlined add
• 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 protocols for link and path attribute
  measurement. This includes the Link Management
  Protocol (LMP) is included here.
• Functional specification of extensions for
  GMPLS-related routing (OSPF, ISIS) and signalling
  (RSVP-TE) protocols 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 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 Ethernet data paths for
  Ethernet data planes that are already approved by
  an Standards Development Organization (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. 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.

5
Proposed changes Work

• Update to reflect current major work items
• WSON, OTN, MPLS-TP (planned)
• Allow for extensions/continuation of prior work
• Such as base protocols and ASON
• Driven by data plane behavior

6
Proposed changes Work (cont.)

• Proposed language
• red delete, underlined add
• 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 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. 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 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 requirements for supporting
  extensions to data plane technologies (e.g. WSON,
  OTN, MPLS-TP and Ethernet) and network
  architectures (e.g., ITU-Ts Automatically
  Switched Optical Network (ASON) are) 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, L1VPN and PCE. The WG will
  also cooperate with the ITU-T and the IEEE 802.1.
