4. ebXML Messaging Version 3.0 Part 1: Core Specification

5. New ebMS 3.0 Concepts & Features
Processing Modes
Parameters for capturing, expressing, sharing configuration choices, message QoS.
Message Pull Feature
Message Receiver Polls the Message Sender
Consumer “receives” messages by pulling them from Sender
Benefit: Supports Small and Medium Size Enterprises
Occasionally connected, no fixed IP address, behind firewalls
Message Partition Channels
Messages assigned to channels
Supports priority handling
Processing Modes: Explain relationship w/ CPA.
Client-Only Partners  Message Pulling
Selective Transfer  Message Channels
(message pulling, channels, MECs, headers, message authorization,
non-repudiation support, compliance with SOAP/WS/WS-I).

7. AS4 Profile

8. AS4 – The lightweight solution
Message packaging governed by ebMS 3.0
Support for both document push and pull message exchange choreographies
Message security governed by WS-Security with added support for payload compression
Support for an AS2-like business-level Non-Repudiation Receipt (MDN)
Reception Awareness – “just enough” reliable messaging (similar to AS2 and ebMS 2.0)
Suitable for SME/lightweight clients

9. AS4 compared to AS2 AS4 has comparable features to AS2 including:
Document push message exchange patterns
Support for Non-Repudiation Receipts
Support for “lightweight” reliable messaging
Support for common security aspects like digital signatures, encryption, and payload compression
AS4 additionally supports the following features not available in AS2:
Document pull message exchange pattern including support for secure access to Message Processing Channels
Native support for Web Services
Support for “lightweight” client implementations

10. ebMS3/AS4 Implementations
Known implementations
Axway, Fujitsu, NEC, Cisco, Data Applications Limited, ENEA, Flame Computing, NEC
Other implementations have expressed interest in interoperability testing.
Open Source: Holodeck

13. Multihop: ebMS Messaging Across Intermediaries

14. Intermediaries No direct connection between MSH
Connections (store & forward) between two light clients

15. Multi-hop: hub and spoke

16. Multi-hop: Inter-connected hubs

17. Multi-hop: hierarchical

18. Bundling, Splitting, Joining, Compression

19. Bundle, Split, Compress Decouple “logical” from “physical” message
Many small messages with same destination, submitted in a short interval, are more efficiently sent as a single ebMS SOAP message bundle
A (very) big message is more effectively sent as a series of smaller message fragments
Reduce data to send by using message compression
Applies to large messages and to bundles
Also covers (verbose) message headers

20. Application Scenarios
Bundling
High volume, non real-time transactions involving small payloads
Event reporting and data synchronization
Any legacy batch application
Splitting
Messages with large payloads, or with many payloads
Compression
Payloads and message headers

21. Implementation Flexibility
Specification concerns interoperability only
Configuration parameters constrain what (not) to bundle, size/timing parameters, policy ..
Allows for optimization and differentiation
No impact to users:
Can be handled within MSH, no change to submission/delivery
Simple features that compose with other ebMS3 functionality
Pull, push, reliable messaging, security …

22. Compression Case Studies
Case Study 1 : GS1 Data Synchronization - Sample bundle containing 23 GDSN 2.7 messages
Without Compression
Total size of messages
306K
ebMS eb3:UserMessage header overhead
19K (6%)
With Compression
Total after bz2 compression
13K (4%)
Case Study 2: eCom 2.6 order
Without Compression
2.6 order (11 docs)
83K
UBL 2.0 (13 docs)
11.8K
With Compression
Total after bz2/zlib compression
8% (worst case)
Comparison with payload compression:
Best case 14%; worst case 25%
Use bundle, split and compress to “optimize” message sizes

23. Summary

Is not in any other WS-* specification
Only exists in (industry) niche B2B or MFT protocols
Is handled (redundantly) at the application layer

Motivation behind ebMS3:
ebMS 3.o Core was released 5 years beyond V2 release, which has seen much success, as described earlier. The technology base changed, and eBusiness practices are as well.
Lower-levels of Web Services protocol stack have been standardized; much of what ebMS 2 described (reliability & security) are now ready for adoption, and ebMS 3 is much simplified by deferring to these new standards to achieve the required functionality.
In addition, we have met new customer requirements to support small- to medium- size enterprises (SMEs); and for more flexibility in partitioning messages into separate, named channels.
Will describe each of these, starting with WS Convergence…

32. Testing and Certification
Drummond Group is planning for the following upcoming testing events:
A week-long “virtual” BAKEOFF ideally in early December 2010 to demonstrate AS4/ebMS3 interoperability
Followed by a live BAKEOFF event at a TBD conference or expo in early 2011
A full-matrix interoperability Certification Test in 1H2011
Perhaps some of these testing events will be sponsored or co-sponsored by OASIS
