Final Charter for Working Group

The advent of switched multi-channel (e.g., WDM, DWDM, OTDM) optical
networks using OXCs (Optical Cross-connects) and other optical
switching elements presents many new opportunities for improving the
performance of IP networks and supporting faster and more flexible
provisioning of IP services. However, much needs to be specified
before interoperable products based on these technologies can be
deployed in service provider networks. The work needed in this area

  • Document the use of existing framing methods for IP over optical
    dataplane and control channels, and as necessary specify additional
    framing methods.

  • Identify and document the characteristics of the optical transport
    network that are important for selecting paths for optical channels,
    setting-up optical channels, and tearing-down optical channels.

  • Document the applications of the common control and measurement
    protocols to the technology-dependent aspects of optical path setup,
    teardown, and maintenance of optical channels across networks with
    optical components.

  • Document the requirements for control of optical networks by elements
    outside the optical network itself.

  • Document the applicability of IP-based protocols for the controlled
    dissemination of optical network topology, metric, and constraint
    information. Such information can be used for inventory management,
    path selection, and other purposes. The information to be exchanged
    should accommodate both all-optical and optical-electrical-optical
    switching technologies.

  • If a need is identified to develop new protocols or make
    incompatible modifications to existing protocols (e.g., routing and
    signaling protocols) to accomplish the above goals, then a recharter
    must first be approved before undertaking such work.

The IP over Optical WG will coordinate with relevant working groups
within the IETF to leverage existing work. The WG may also generate
requirements for other IETF WGs as needed. Additionally, the WG may
collaborate with other standards bodies and interoperability forums
engaged in IP over optical activities (e.g., including ITU-T) to share
information, minimize duplication of effort, and coordinate activities
in order to promote interoperability and serve the best interest of
the industry.
