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
