  1. ECTS/ECTP Test plan Dae Young KIM dykim@ccl.cnu.ac.kr (Chungnam Nat'l Univ. South KOREA)

  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

  8. ECTP Overview • ECTP Protocol Stack • Six Parts of ECTP • Simplex reliable(1), simplex QoS(2), • Duplex reliable(3), duplex QoS(4) • Nplex reliable(5), Nplex QoS(6)

  9. ECTP-Relationship between P1 & P2

  10. CR Local HB Scalable ECTP • Tree Structure for Control Message • one TO(Top Owner), • zero or more LO(Local Owner), LE(Leaf Entity)

  11. ECTP-Part1 • Simplex Reliable Multicast • Tree configuration for scalability • Window based flow control • Selective ACK with bitmap • Session Control • Connection management • Late join/Leave • Tree membership maintenance

  12. ECTP-Part2 • QoS Negotiation • In The Connection Setup Phase • QoS Monitoring • Throughput • Loss rate • Delay & jitter • QoS Maintenance • Adjustment of data transmission rate • Connection pause/resume/termination
