July 15, 2003IETF 57 - Wien Overview v2 is rewritten, v3 is born: –Updated according to RFC editor’s comments –Thoroughly rewritten: several definitions clarified, new ones added, some unnecessary ones are deleted –Now consistent with NSIS drafts –BUT: no change in the philosophy

July 15, 2003IETF 57 - Wien 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, 2003IETF 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

July 15, 2003IETF 57 - Wien 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, 2003IETF 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

July 15, 2003IETF 57 - Wien Definitions 6.1 Traffic Flow Types Data Flow Distinguished Data Flow Best-Effort Data Flow 6.2 Resource Reservation Protocol Basics QoS Session Resource Reservation Protocol Resource Reservation Capable Router Reservation State Resource Reservation Protocol Orientation 6.3 Router Load Factors Best-Effort Traffic Load Factor Distinguished Traffic Load Factor Session Load Factor Signaling Intensity Load Factor Signaling Burst Load Factor 6.4 Performance Metrics Signaling Message Handling Time Distinguished Traffic Delay Best-effort Traffic Delay Signaling Message Loss Session Maintenance Capacity 6.5 Scalability Limit

July 15, 2003IETF 57 - Wien Future Need comments! –Draft was sent to the NSIS WG also
