E N D
Overview • Part 1: Core Specification – Summary • AS4 – Introduction • Part 2: Advanced Features – Overview and examples
ebXML Messaging 2.0 & 3.0 High Level Capabilities • 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
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 • 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 – 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: • 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). • Open Source: Holodeck • http://holodeck-b2b.sourceforge.net/

ebXML Messaging 3.0 Part 2: Advanced Features OASIS ebXML Messaging TC
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
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 message headers • Composes well with multi-hop intermediary features
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
Compression Case Studies • Comparison with payload compression: • Best case 14%; worst case 25% • Use bundle, split and compress to “optimize” message sizes
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 • Enables SME-to-SME message exchange across I-Cloud • Supports flexible and scalable topologies • Bundling • Support efficient high-volume message exchange • Split, join, compress • Support efficient transfer of very large messages (and message bundles)
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
Q & A • ……….
Transparent Multihop • End-to-end Business Agreements • Service, action, identification, document schemas • End-to-end Security • Non-repudiation of origin and receipt • Confidentiality • End-to-end Reliability • Retries, acknowledgments • ebMS intermediaries interconnect the I-Cloud • Service, action, identification, content schemas • Routing • Based on Business Identifiers and Services • Storage • Store-and-forward (push), store-and-collect (pull) Receiver Sender • Point-to-point Techical Configuration for Edge Hops • Transport Protocol Binding (HTTP, SMTP) • Transport Security (SSL/TLS) • Transport Channel Binding (Push, Pull) • Inter-hop Configuration within the I-Cloud • Transport Protocol Binding (HTTP, SMTP) • Transport Security (SSL/TLS) • Transport Channel Binding (Push, Pull) • Store-and-forward or streaming
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
