EbXML Messaging Version 3.0 Parts 1, Part 2 and AS4

ebXML Messaging Version 3.0 Parts 1, Part 2 and AS4

Overview

Part 1: Core Specification – Summary AS4 – Introduction Part 2: Advanced Features – Overview

and examples

ebXML Messaging 2.0 & 3.0

Message Header with Business Metadata Identifies Business Partners, Transaction Semantics, Context,

Agreement, Properties, Payloads Reliable Message Delivery

At-Least-Once, At-Most-Once, In-Order delivery Security

Digital Signature and Payload Encryption Support for Non-Repudiation of Origin & Receipt

Leverages SOAP, MIME envelopes XML, EDI, multimedia payloads Multiple payloads per message

Transport Protocol Mappings for HTTP and SMTP Composition with other eBusiness Components

High Level Capabilities

ebXML Messaging Version 3.0Part 1: Core Specification

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

AS4 Profile

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

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

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

ebXML Messaging 3.0 Part 2: Advanced Features

OASIS ebXML Messaging TC

Multihop: ebMS Messaging Across Intermediaries

Intermediaries

No direct connection between MSH Connections (store & forward) between

two light clients

Multi-hop: hub and spoke

Multi-hop: Inter-connected hubs

Multi-hop: hierarchical

Bundling, Splitting, Joining, Compression

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

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

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 … Backup

Compression Case Studies

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

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

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)

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

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
