Parameters for capturing, expressing, sharing
configuration choices, message QoS.

Consumer “receives” messages by pulling them from Sender
Occasionally connected, no fixed IP address, behind firewalls

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 NonRepudiation 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

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

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




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
Features

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

Pull, push, reliable messaging, security …
Case Study

GS1 Data Synchronization:




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:


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%
Best case 14%; worst case 25%
Use bundle, split and compress to “optimize”
message sizes

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
