Hi Adrian, I think that it would be convenient for the WG to include a slot for discussion (not presentation) of the draft on diverse path requirements routing (namely: draft-dachille-diverse-inter-region-path-setup-00.txt ). In the current version of the agenda for San Diego I do not see any reference to that, despite in the Seoul meeting it was acknowledged to be a very important work. That time it was state that it should be discussed in the list and revised. I´m attaching an extract from the Seoul minutes at the end of this mail, for reference. Well, both an _intensive_ discussion and a careful revision have been carried on for over 2 months now. The discussion was fruitful indeed, and in the revision we have addressed _all_ the comments issued so far. The feedback were generally very positive. Therefore, considered the very high level of interest that has been demonstrated for this topic, I do not see any reson for not having the chance to discuss the changes introduced in the revised version in San Diego in order to advance it in the WG. I remark that the draft directly addresses a significant number of charter items: -- Functional specification of extensions for routing (OSPF, ISIS) and signalling (RSVP-TE) required for path establishment. -- Define signaling and routing mechanisms to make possible the creation of paths that span multiple IGP areas, multiple ASes, and multiple providers, including techniques for crankback -- Specify signalling mechanisms for path protection, diverse routing and fast path restoration.
