  1. The Early Life of WS-ReliableMessaging Where we are, and how we got here Jorgen Thelin Program Manager – WS-* Workshops Microsoft Corporation

  2. Summary of RM Workshop History • 1 Feedback Workshop • 3 Interop Workshops • 14 Workshop Participants • Apache, BEA, Blue Titan, Fujitsu, IBM, Iona, Microsoft, NEC, RogueWave, SAP, SeeBeyond, Sonic, Systinet, TIBCO • 9 Workshop Implementations • Apache Axis, BEA, Blue Titan, IBM, Microsoft, SAP, Sonic, Systinet, TIBCO • 7 Main Interop Scenarios (plus variants) • At least 7 Currently Shipping Products (Beta+) • Apache Axis, BEA, Blue Titan, Cape Clear, IBM, Microsoft, Systinet

  3. WS-RM – Birth and Early Childhood • July 2003 - Feedback Workshop • 12 Participants: • BEA, Blue Titan, Fujitsu, IBM, Iona, Microsoft, NEC, SAP, SeeBeyond, Sonic, TIBCO • Presentation Topics • RM Scenarios • RM Protocol Overview and Walkthrough • RM Scalability and Durability • RM and Security Demo • WS-ReliableMessaging Scalability and Durability

  4. WS-RM – Pre-Teen • Oct 2003 - First Interop Workshop • 7 Implementations: • BEA, Blue Titan, IBM, Microsoft, Sonic, Systinet, TIBCO • Interop Scenarios: • Reliable One-way Ping without Failure • 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 • Each message is independent • 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 • Each message is independent • Variations: • number and timing of Acks sent • Synchro vs async acks • Time of failure

  7. WS-RM – Teenage • May 2004 – Second Interop Workshop • 4 Implementations: • BEA, IBM, Microsoft, Apache Axis - Sandesha (Virtusa / Lanka Software Foundation) • 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 • Request/Response • Variations: Async + Synchronous Acks • Request/Response coupled with Resource Reclamation • AckRequest

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

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

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

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

  12. WS-RM – Young Adult • April 2005 - RM + Security Composition Workshop • 4 Implementations: • IBM, Microsoft, SAP, Systinet • Interop Scenarios: • Un-secure RM One-Way Ping (Baseline regression test) • Secure RM One-Way Ping

  13. Scenario #7 – Secure RM

  14. WS-RM – Summary of Spec Refinements Made • NACK • Resource reclamation points • Extensibility points • Absolute URI (vs. relative) • Sequence expiration • Last Message and ACK usage • Clarified SOAP mustUnderstand usage • Clarified FAULT handling • RM Policy assertions

  16. WS-RM - Ongoing Interop Testing • Public interop endpoints available for on-going testing • Microsoft • Secure RM:http://131.107.153.195/SecureReliableMessaging/SecureReliableOneWayDual.svc • Unsecured RM - One-Way: http://131.107.153.195/SecureReliableMessaging/ReliableOneWayDual.svc • Unsecured RM - Request-Reply: http://131.107.153.195/SecureReliableMessaging/ReliableRequestReplyDual.svc • IBM • Secure and Unsecured RM:http://wsi.alphaworks.ibm.com:8080/wsrm • Systinet • Secure RM:http://soap.systinet.net/ws/wssc/Service • Unsecured RM: http://soap.systinet.net/interop/wsrm.html

  17. WS-RM – Ready for Adult Life • 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
