2. Contents ECTS overview ECTP overview ECTP test plan

3. ECTS Overview(1)

4. ECTS Overview (2) Characteristics Various Group Transmission Mode Simplex, Duplex, N-plex Reliable / Unreliable / Semi-reliable Transmission QoS Selection Assumes network QoS (RSVP, DiffServ, …) QoS value is defined by boundary (CHQ, OT, LQA) Selection by negotiation Group Membership Management AGI (Active Group Integrity) Session Management Setup/pause/resume/termination/join/leave

5. ECTS Overview(3) Some Peculiar Service Primitives Session Setup creation/termination/join/leave/invitation Maintenance TC pause/resume/ report Ownership transfer N:N Data Transfer Reliable/Unreliable Data Transmission Token give/get

6. QoS Defined in ECTS(1) QoS Classes Performance Throughput/Delay/Delay Jitter reliability Corrupted/Lost error rate ordering no/local/causal/partial/total ordering miscellaneous protection/precedence QoS Value Defined with 3 number (CHQ, OT, LQA)

7. QoS Negotiation in ECTS
