ebXML Messaging Version 3.0
Part 1: Core Specification
New ebMS 3.0 Concepts & Features

Processing Modes


Parameters for capturing and expressing configuration
choices (Message Exchange, Reliability, Security etc.).
Message Pull Feature

Message Receiver Polls the Message Sender


Benefit: Supports Small and Medium Size Enterprises


Consumer “receives” messages by pulling them from Sender
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 NonRepudiation 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:



Message pull operation 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
Other implementations have expressed interest in
interoperability testing (scheduled for 2011).

Multihop: ebMS Messaging
Across Intermediaries
Intermediary Cloud



No direct connection between endpoints
End to end secure, reliable routing of
messages across the Cloud
Enables connections (store & forward)
between two light clients

Bundling, Splitting, Joining,
Compression
Bundle, Split, Compress

Decouple “logical” from “physical” message



Reduce data to send by using message compression



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
Applies to large messages and to bundles
Also covers message headers
Composes well with multi-hop intermediary
features
Application Scenarios

Bundling




Splitting


High volume, non real-time transactions
involving small payloads
Event reporting and data synchronization
Any legacy batch application
Messages with large payloads, or with many
payloads
Compression

Payloads and message headers
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 2/3: eCom 2.6 order & UBL

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

B2B protocol with the broadest coverage of
user deployment scenarios







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

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