4 WS-RM – Pre-Teen Oct First Interop Workshop Oct First Interop Workshop –7 Implementations: BEA, Blue Titan, IBM, Microsoft, Sonic, Systinet, TIBCO BEA, Blue Titan, IBM, Microsoft, Sonic, Systinet, TIBCO Interop Scenarios: Interop Scenarios: –Reliable One-way Ping without Failure Variations: Async + Synchronous Acks Variations: Async + Synchronous Acks –Reliable One-way Ping with Communication Failure

5 Scenario #1 - Reliable One-way Ping without Failure Basic form of reliable message exchange in the normal case Basic form of reliable message exchange in the normal case Each message is independent Each message is independent Variations: Variations: –number and timing of Acks sent –Synchro vs async acks

6 Scenario #2 - Reliable One-way Ping with Failure Tests a reliable message exchange in the presence of a simple failure model involving communication failures Tests a reliable message exchange in the presence of a simple failure model involving communication failures Each message is independent Each message is independent Variations: Variations: –number and timing of Acks sent –Synchro vs async acks –Time of failure

7 WS-RM – Teenage May 2004 – Second Interop Workshop May 2004 – Second Interop Workshop –4 Implementations: BEA, IBM, Microsoft, Apache Axis - Sandesha (Virtusa / Lanka Software Foundation) BEA, IBM, Microsoft, Apache Axis - Sandesha (Virtusa / Lanka Software Foundation) Interop Scenarios: Interop Scenarios: –Reliable One-way Ping Without Failure (Baseline regression test) –Reliable One-way Ping With Failure (Baseline regression test) –Resource Reclamation Variations: Async + Synchronous Acks Variations: Async + Synchronous Acks –Request/Response Variations: Async + Synchronous Acks Variations: Async + Synchronous Acks –Request/Response coupled with Resource Reclamation –AckRequest

8 Scenario #3 - Resource Reclamation Reliable message exchange with explicit sequence creation / termination Reliable message exchange with explicit sequence creation / termination Variations: Variations: –number and timing of Acks sent –Synchro vs async acks

9 Scenario #4 - Request/Response Pairs of reliable request and response messages Pairs of reliable request and response messages Tests InOrderExactlyOnce delivery assurance Tests InOrderExactlyOnce delivery assurance Variations: Variations: –Synchro vs async acks

10 Scenario #5 - Request/Response with Resource Reclamation Reliable request / response message exchange with explicit sequence creation / termination Reliable request / response message exchange with explicit sequence creation / termination Async acks Async acks

11 Scenario #6 - AckRequest Basic form of reliable message exchange in the normal case Basic form of reliable message exchange in the normal case Each message is independent Each message is independent Variations: Variations: –number and timing of Acks –Send AckRequest on each Ping message

17 WS-RM – Ready for Adult Life WS-RM is a healthy and mature spec with most of the “growing pains” now past WS-RM is a healthy and mature spec with most of the “growing pains” now past –Implementability has been verified –Interop has been verified –Composability with other WS-* specs has been verified –Spec has been refined as a result of feedback and experience

18 And Finally…. Thank You to all the participants in the WS-ReliableMessaging Workshops who helped shape the WS-RM Spec into what it is today Thank You to all the participants in the WS-ReliableMessaging Workshops who helped shape the WS-RM Spec into what it is today
