Description of Working Group:

Resilient Packet Rings, under development within the IEEE's 802.17 RPRWG, will provide substantial enhancements in both efficiency and flexibility over current bi-directional ring topologies. Benefits of resilient packet rings (RPRs) will include spatial re-use (full utilization of both counter- rotating rings) while maintaining APS-like protection switching during media faults. The 802.17 RPRWG may develop mechanisms for topology discovery, congestion control, and protection switching. Reference the IEEE 802.17 RPRWG at http://www.ieee802.org/rprsg/index.html for further information.

In particular, the IPoRPR Working Group would produce a requirements and framework document which will be used as input to the IEEE RPRSG to help it formulate its requirements. Areas which are of particular interest to the IPoRPR Working Group will involve the layer 2 to layer 3 interaction in areas such as:

- alarm notification

- fast restoration

- fast convergence

- traffic engineering (e.g. resource availability/usage information)

- quality of service issues

This work is specifically being done in parallel with the IEEE effort so that cross fertilization between the IEEE and IETF groups takes place while the IEEE standard is being developed.

The requirements and framework document will:

- Clearly state requirements for L2-L3 interaction within these rings

- Highlight the motivation and associated benefits

- Define key components, Layer abstractions and partitioning

- Document assumptions, any observations and issues

- Formulate the mechanisms required to accomplish IP-awareness within these Resilient Packet Rings

The IPoRPR 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.

The WG will not address issues that are clearly within the MAC Layer and will not develop any protocols at this time. No formal liaison with the IEEE is anticipated. It is expected that individuals will participate directly in both groups.

Goals and Milestones:

MAR 01		Initial Requirements & Framework Document submitted as an Internet-Draft
AUG 01		Submit Requirements and Framework Document to IESG as informational
AUG 01		Recharter or shut down
