New in ebMS 3.0 Core Further Web Services Convergence

SOAP 1.1 or SOAP 1.2 SOAP with Attachments or MTOM WS-Security 1.0 or 1.1 WS-Reliability 1.1 or WS-

ReliableMessaging 1.1/1.2 Compatible with WS-I profiles

Meets new user requirements SME endpoints, message partitioning

New ebMS 3.0 Concepts & Features

Processing Modes Parameters for capturing, expressing, sharing

configuration choices, message QoS. Message Pull Feature

Message Receiver is Polling 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

AS4 Profile

AS4 Profile 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)

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 MPCs

Native support for Web Services Support for “lightweight” client implementations

ebMS3/AS4 Implementations OASIS successful use statements (2007):

Axway, Fujitsu, NEC Vendor implementations

Cisco, Data Applications Limited, ENEA, Flame Computing, Fujitsu, NEC

Other implementations have expressed interest in interoperability testing, but have not yet been publicly announced

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

Multihop: ebMS Messaging Across Intermediaries

Intermediaries

Multi-hop: hub and spoke

Multi-hop: connected hubs

Multi-hop: hierarchical

Bundling, Splitting, Joining, Compression

Bundle, Split, Join, 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

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

Features 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 …

Case Study GS1 Data Synchronization:

A sample bundle containing 23 GDSN 2.7 messages; total 306K

ebMS3 eb3:UserMessage header overhead: 19K (6%)

Total after bz2 compression: 13K, i.e. 4% Other case studies

eCom 2.6 order (11 docs, 83K), UBL 2.0 (13 docs, 11.8K), bz2/zlib compression: worst case 8%

Comparison with payload compression: Best case 14%; worst case 25%

Use bundle, split and compress to “optimize” message sizes

Summary

ebMS 3.0 (and AS4) ebMS 3.0 Core Specification

WS-* based WS-I profiles compliant Functional superset of ebMS 2.0 Important extensions for Small and Medium-Size

businesses AS4

Profile of Core Specification Functional superset of AS2 Adds payload compression, Non-Repudiation of

Receipt, Reception Awareness

Part 2: Advanced Features Intermediaries

Enable SME-to-SME message exchange Bundling

Support efficient high-volume message exchange

Split, join, compress Support efficient transfer of very large

messages (and message bundles) Variants in MEP Execution

Better Pull and Sync replies

ebMS 3.0 Parts 1, 2 and AS4 B2B protocol with the broadest coverage of

user deployment scenarios Push, Pull and Synchronous exchanges From light-weight clients to high-end B2B gateways Point-to-point exchange and multi-hop exchanges From occasional exchanges to very high volume

exchanges From small message exchanges to very large

message exchanges Web Services based functionality that:

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