RFC Editorial remarks
• draft-ietf-bmwg-benchres-term v2:– sent to the RFC editors, bounced back with some
comments
• Main remarks– Consistency with NSIS?– Slightly confused about diffserv– Referring to the Boomerang protocol
(research paper from the same authors)– Too much opinion (prejudgments) in a terminology
July 15, 2003 IETF 57 - Wien
Updates based on remarks
• DiffServ parts are completely removed– No support for signaling protocols utilizing
DiffServ architectures (e.g. RODA)
• Boomerang protocol– NSIS presents it in its analysis draft!– Anyway, no special features are mentioned
• No more prejudgments

NSIS consistency
• NSIS Framework – close to Last Call!– NSIS terminology does not replace this
draft, but we can be consistent with its philosophy
• We think that it is NSIS conform now!– It was, so no big changes
July 15, 2003 IETF 57 - Wien
New version: 02 -> 03
• Most important changes– A more precise QoS Session definition
(Previously Resource Reservation Session)
– New terms: Reservation States/Resource Reservation Protocol
– Unnecessary terms are removed– Many clarifications– BUT no change in the philosophy
