DiffServ QoS model (RMD) A. Bader, G. Karagiannis

Current DiffServ Traffic differentiation Admission/policy control at the borders, simpler functions in the interior nodes No QoS signaling within the domain RMD QoS signaling within the DiffServ domain and can be extended to multi-domain Provides dynamic QoS support, better link utilization Scalable (complexity at edge, simple in interiors)

DiffServ QoS signaling model RMD in NSIS Edge Interior Edge DiffServ domain Interior: No per flow states: only per PHB states and no NTLP states Local QSpec: bandwidth + control flags Per flow NTLP and NSLP states QSpec: token bucket or more complex descriptors End Per flow NTLP and NSLP states

Reduced state operation model of NSIS IP QoS- NSLP E2E QoS model NTLP User application IP NTLP IP NTLP/D-mode IP NTLP IP NTLP User application Initiator Receiver Edge Interior E2E QoS model Local-QoS E2E QoS model Local-QoS NTLP and NSLP per- flow states NTLP stateless per- class or no NSLP states QoS- NSLP NTLP and NSLP per- flow states NTLP and NSLP per- flow states NTLP and NSLP per- flow states

RMD QSpec Bandwidth or number of resource units Additional control information (fields and flags) as a consequence of the stateless operation: TTL, M, S, etc. Question: Should we continue working on RMD model as a WG draft towards inf. or exp. RFC?

Successful reservation Initiator ReceiverEdge Interior Resv(QSpec) Resv(E2E ignore, QSpec) Resv(QSpec) Resv(LQSpec) Response

Failed reservation Initiator ReceiverEdge Interior Resv(QSpec) Resv(E2E ignore, QSpec) Resv(LQSpec) Resv(LQSpec:M-marked) Response: Congestion rep. Response Resv(LQSpec:M-marked) Unsuccesful resv. Resv(Tear) Resv(Tear, TTL=1)

Severe congestion handling by data marking Initiator ReceiverEdge Interior User Data Data: S-marked Resv(Tear) Response: Congestion rep. Severe congestion Resv(Tear)

Aggregation types RSVP aggregation-like –topology dependent (aggregation of flows between aggregation points) –aggregation per DSCP –statefull nodes –aggregated refreshes RMD-like –topology independent, aggregation per DSCP only –statefull edges, stateless interior –per flow refreshes Combination of the two types
