WG Review: IP over Optical (ipo)
A new IETF working group has been proposed in the IETF.
The IESG has not made any determination as yet.

Description of 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
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 and tearing-down optical
- Document the application of the common control and measurement
protocols to the technology-dependent aspects of optical path setup,
teardown, and measurement of optical channels across networks with
- Document requirements for control of optical networks by
elements outside the optical network itself.
- Document the use 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
- 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.
