This BOF is for the discussion of AAA protocol requirements and potential solutions. One working group, the RSVP Authentication and Policy (RAP) WG has been working on a protocol API that will enable AAA services to be offered to RSVP routers and hosts by a central server; other working groups are interested in AAA services as well. An alternative proposal, DIAMETER, has been proposed and is being seriously considered by some. We want to meet to discuss the requirements of various working groups, consider the alternatives, and recommend a technical direction. Possible outcomes include a working group, or a recommendation that DIAMETER be placed on the standards track as an individual submission, or that COPS be extended to meet various needs, or that other approaches be considered.
