Introduction“Eighty-five percent of CEOs plan to partner to capitalize on global integration opportunities—more than half plan to do so extensively. We also found that outperformers are 20 percent more likely to partner extensively than underperformers. This reinforces what was discovered inthe last CEO Study: extensive collaborators outperform their competitive peers.”—IBM Global CEOStudy 2008.

As companies are forced by market drivers to become globally integrated enterprises, they increasingly

need to expand their ecosystems with more and more partners. This expansion increases the need for

channel integration. Business-to-business (B2B) projects play a critical role in channel and partner

integration with a fundamental challenge of seamless, secure and reliable integration across a

multienterprise value chain. Multienterprise data, process and application integration needs are rapidly

growing, and so B2B projects are proliferating.

The IT user’s challenge is to consistently manage a B2B abstract layer in a multienterprise integration

environment to quickly support new, emerging and proliferating transport and communication protocols,

standards, and integration technologies as required to support dynamic business needs. Primarily,

customers are looking for the following value from a B2B integration provider:

● A single, cost-effective, easy-to-use package based on a powerful management-by-exception paradigmthat reduces ongoing operational costs

● A B2B gateway that allows modular configuration and reusable building-block approaches, delivering large-scale, rapid onboarding of trading partners, low maintenance and strong return oninvestment (ROI)

● An architecture that delivers scalability for both small- and large-scale implementations, supportingmission-critical business processes with automated enablement and comprehensive event support,delivering extreme scalability for even the most demanding workloads, full extensibility and broadinteroperability—validated in many small and large innovative deployments across the globe


These critical needs arise from recent business and market dynamics such as supply chain integrations,

mergers and acquisitions, or spin-offs. As departments increasingly consolidate trading partners into their

processes, information exchange is exploding. Data transfer size and frequency are growing at a rapid pace.

The need for B2B Integration is crucial for a multienterprise business process platform (ME-BPP). A B2B

solution is a critical component of any IT portfolio that addresses a multienterprise integration strategy.

How the IBM B2B solution approach enables innovation and businessvalueIBM’s approach to B2B solutions is influenced by our customers’ needs and feedback, market trends,

the evolution of standards and technology, customer buying patterns and the input of leading analysts.

IBM also aims to align its B2B solutions with the IBM business process management (BPM) and

application integration (AI) components of our service oriented architecture (SOA) offerings. This approach

ultimately influences how we define our strategy for our B2B solution. IBM’s focused strategy and

investment for B2B solutions is based on these key factors:

● B2B needs are increasingly driven by a need for flexibility and agility to support continuous businessmodel innovation. As part of the need for companies to embrace this “flat world” model, companiesare expanding the partner ecosystem to support their core processes.

● B2B Integration is an integral part of SOA-based integration platforms, where the distinction betweenapplication-to-application or A2A (intraenterprise) and B2B (interenterprise) communication blursover time. An increasing number of common infrastructure services (for example, transformation,process execution, registries, directories and Internet standards) are being shared and reused bydevelopers.— This is in contrast to a historical paradigm where organizations have implemented B2B

capability as an entirely stand-alone, edge-of-the-enterprise function.— This is consistent with SOA to enable consistent description and connectivity among dissimilar

existing applications using a common metadata framework. (SOA is also backward-compatible,evolutionary, intelligent, sustainable middleware that can allow enterprises to better track andleverage existing assets.)


● B2B Integration is very process-conscious, where customers connect internal processes with B2B flowsas part of the enterprise BPM platform and standardize on common standards such as Web ServicesBusiness Process Execution Language (WS-BPEL) and Web services. These connections can includethe modeling of existing electronic data interchange (EDI) and XML messages, where process logicand business rule relationships can be created between purchase orders and invoices, and where rulesassociated with timeliness, cardinality (one-to-many relationships between messages), as well as rolesand responsibilities of trading partners, can be defined and enforced. This trend builds upon andextends process-conscious B2B exchanges such as PIPs pioneered by RosettaNet from UML models.

● B2B Integration includes several components:

— Existing B2B standards will evolve to make even stronger use of XML, Web services and otherInternet standards. Business process solutions supporting B2B interactions will increasingly bedescribed and exposed through Web service interfaces to support noninvasive interoperabilitywith trading partners. This is very similar to how A2A interactions are described.

— IBM expects more B2B standards in various industry verticals that have been historicallymessage-based. These standards will evolve to embed business process and rules intelligence. Wesee this happening with Web Services Interoperability Organization (WS-I) profiles, ElectronicBusiness using eXtensible Markup Language (ebXML) message handling (with action headers)and chemical industry data exchange (CIDX) messages and continuing to mature withinRosettaNet Partner Interface Processes (PIPs).

— Connectivity services— Industry standards (AS1, AS2 and AS3)— Nonrepudiation of data— Transformation services (EDI, for instance)— Process execution capabilities (B2B protocols)— Integration (with internal processes, systems and people)— Monitoring capabilities at the business level and the IT level— Trading partner management and governance over trading partner relationships

● B2B Integration extends BPM beyond the enterprise to a company’s network of partners. The IBM WebSphere® Partner Gateway solution provides the structured partner management andgovernance for this interaction as B2B and BPM dependencies become stronger.


IBM’s leadership, through our knowledge and long history of expertise in the B2B sector, allows us to

deliver a comprehensive and differentiated B2B solution called WebSphere Partner Gateway.

IBM WebSphere Partner Gateway is an integrated B2B environmentWebSphere Partner Gateway is a complete set of integrated B2B capabilities, in a single, cost-effective,

easy-to-use package. The solution is based on a powerful management-by-exception paradigm that reduces

ongoing operational costs. WebSphere Partner Gateway provides these benefits:

Its community management paradigm uses an SOA-based, modular approach based on reusable building

blocks with partner self-service capabilities. This approach delivers large-scale, rapid onboarding of trading

partners, low trading-partner maintenance costs and strong ROI.

1. Its SOA-based extensibility framework delivers the flexibility required for applications that can range

from large-scale, innovative, global B2B implementations to “niche” gateway applications.

2. Its SOA architecture delivers comprehensive, event-based BPM integration, extreme scalability even

under the most demanding workloads and broad interoperability—as validated in large, innovative

deployments across the globe.

Figure 1: WebSphere Partner Gateway: a highly scalable, components-based integrated B2B environment


The current customer adoption of IBM B2B solutions has expanded well beyond our earlier focus on

RosettaNet and supply chain management processes (order management, purchase and planning

management and inventory management) to varied business areas across every major industry. These

include banking, telecommunications, airlines, cargo, insurance, education, health care, logistics and high-

tech manufacturing.

Partner community management is the core of partner integrationToday’s B2B trading partners expect easy onboarding, self management, granular security settings,

operational reporting, simulation and alerting capabilities from the community. WebSphere Partner

Gateway scores high in each of these areas. WebSphere Partner Gateway is configured using an object-

oriented, modular building-block approach, implemented in an intuitive, Web-based graphical user

interface. The XML-based import/export facility enables rapid onboarding of trading partners in large

volume with minimal effort.

The WebSphere Partner Gateway console is reserved for authenticated users only. Trading partner users

securely log in to the console through a Web browser using their user name and password. Each trading

partner has administrator group users who manage the permission of the other user groups. Trading

partners can manage the certificates that can be configured at the partner, protocol and connection level.

The WebSphere Partner Gateway console ensures confidentiality by allowing trading partners to view only

the documents that were sent or received by them.

Reporting tools in WebSphere Partner Gateway display document information, including payload details,

volume and status, such as overdue EDI functional acknowledgements. WebSphere Partner Gateway

provides a generic document viewer and process-specific viewers for Autonomous System (AS), RosettaNet

and ebMS. This support offers users a wide range of search options so that they can easily locate the

intended business document. Process-related viewers provide specific information for AS, RosettaNet

Implementation Framework (RNIF) and ebXML documents. The document viewer also helps users find the

events associated with any related documents. WebSphere Partner Gateway offers a simple resending option

through the user interface (UI) for the failed documents, which can also stop processing if needed.


Extensive alert and event management capabilities provide standard and trading partner-specific alerts,

based on any of over 300 standard WebSphere Partner Gateway events—or an unlimited number of user-

defined events. Alerts can be based on items such as technical events, business events, volume deviation,

field ranges and more. An alert can also trigger an internal or external Web service, allowing for the

direct invocation of diagnostic or remedial bilateral Business Process Execution Language (BPEL) flows,

collaborative Web services at a trading partner and similar responses. Because WebSphere Partner Gateway

events are generated for both positive and negative events, you can define powerful and innovative process-

collaboration patterns specific to your trading partners.

WebSphere Partner Gateway has strong simulation features that are useful for enterprises before

deploying into production. The RosettaNet Simulator works through the UI to help simulate real-life

RosettaNet document traffic. One trading partner can ping the other ebXML trading partner to get the

response and also test the HTTP destinations of other trading partners.

Secure communication beyond the enterpriseEvery enterprise interacts with its customers, trading partners and suppliers, often exchanging sensitive

business data. They use different communication infrastructures, such as private value-added networks

(private VANs) or public domain Internet. On top of this infrastructure, every business uses different basic

communication transports to transfer their business documents between trading partners, customers and

suppliers and to their own back-end applications. In this way, they can provide a real-time view of their

business transactions to this ecosystem of enterprise, customers and partners.

As the B2B integration enables the information that is available to your partners in real time, it should

also ensure that the information exchanged is protected from all kinds of security exposures. Here are

examples of security requirements for business data exchanged between partners:

● Confidentiality: Data should be read only by the intended partner and should not be read by anyother party.

● Identification and authentication: Data should be received only from a known sender.


● Authorization: The sender or the user should be able to perform only the functions that the userauthorized.

● Nonrepudiation: There must be a way to verify that the data is sent only by the sender and not byanyone else. Also, the sender should not be able to deny sending the data.

A business protocol defines the process, structure and rules of how business documents are exchanged

between trading partners. The business document can be in any format, such as EDI, XML or binary. The

business documents are exchanged between the trading partners over the available communication

channels, adhering to the specifications defined by the business protocol. WebSphere Partner Gateway

supports AS1, AS2, AS3, RNIF, Web Services (SOAP), cXML, ebMS, CIDX and PIDX with a wide range of

data formats, including EDI, text files, binary and XML.

However, the majority of general businesses exchange their business documents using common

communication protocols such as HTTP over SSL (HTTPS), FTP over SSL, Simple Mail Transport

Protocol (SMTP), Post Office Protocol Version 3 (POP3) and Java™ Message Service (JMS). The exchange

of B2B documents over the Internet requires strong security. WebSphere Partner Gateway provides robust

security features at two levels:

● Transport levelWebSphere Partner Gateway supports SSL communication using server-based and client-basedauthentication. This support is available for HTTPS and FTP over SSL. In addition, basicauthentication over HTTP is also supported.

● Document levelAlong with the secure transport, you can also protect the actual document by encrypting and signing it.WebSphere Partner Gateway supports S/MIME-based encryption, as well as signing using severalencryption and signing algorithms. The user can vary the encryption and signing certificates based onthe partner, package, protocol or document type. WebSphere Partner Gateway also provides an interfaceto manage the certificates.


Users can also configure WebSphere Partner Gateway to operate in a mode with Federal Information

Processing Standard (FIPS) 140-2 security, often required for interaction with systems owned by the U.S.

government and other regulated industries (such as financial and health care institutions).

Integration and transformation across heterogeneous IT environmentsRegardless of the B2B gateway vendor, many B2B implementations require some ability to augment the

function provided. Reasons range from a deliberate strategy to innovate or differentiate at the edge of the

enterprise, to the need to support narrowly used B2B standards. WebSphere Partner Gateway provides an

innovative, SOA-based extensibility framework that enables customers to build, encapsulate, govern and

deploy implementation-specific services as part of their B2B implementation. The service encapsulation

mechanism in WebSphere Partner Gateway allows specialized communication protocol handlers, content

recognition routines, compression or encryption algorithms and other programs to be easily registered,

integrated, deployed and protected through the Web-based console for WebSphere Partner Gateway.

By extending the WebSphere Partner Gateway architecture through plug-ins, users can add custom

functions called exits or handlers at different stages of document processing. Besides adding custom

transports, packages, protocols or document types, users can customize existing transports, packages,

protocols and document types. Figure 1 shows the stages of document processing that can be customized.

Figure 2: Customizing document processing in WebSphere Partner Gateway


For example, exits can be used for document encryption, decryption validation and transformation. As

WebSphere Partner Gateway receives and processes a document, it can call another program as part of the

possessing.

Services deployed using the WebSphere Partner Gateway extensibility framework need only be defined

and registered once. That’s because the encapsulation mechanism in WebSphere Partner Gateway protects

the customer’s investment in these services from release to release. Configuration and management

parameters for these services are managed by the same WebSphere Partner Gateway services that manage

the functions of WebSphere Partner Gateway itself. So, for example, if a customer uses the WebSphere

Partner Gateway extensibility framework to create support for a narrowly used communication protocol,

the configuration, administration and management UIs will be the same as those used by the natively

supported WebSphere Partner Gateway protocols. This support provides seamless integration and

management of user-developed capabilities, with no impact on the learning curve of B2B administrative

and operational staff.

WebSphere Partner Gateway services can also be stored in and managed by IBM WebSphere Service

Registry and Repository, IBM Rational® Asset Manager and other third-party service registries in order to

deliver the same level of SOA governance for the ”edge of the enterprise” as for internally deployed

services.

Interoperability of WebSphere Partner Gateway with competitive B2B gateways and gateway components

has been validated through third-party interoperability testing (for example, Drummond certification), as

well as large customer deployments with thousands of trading partners across the globe.

WebSphere Partner Gateway provides stand-alone B2B gateway capabilities for standard B2B integration

needs. The solution also provides extended capabilities in conjunction with other connectivity solutions

(such as an enterprise service bus, or ESB) to integrate across various enterprise applications. The

documents that are received by WebSphere Partner Gateway usually need to be processed by one or more

internal applications. WebSphere Partner Gateway can interact directly with those internal applications

using JMS, HTTP or the file system.


For more complex integration scenarios, it is common for WebSphere Partner Gateway to interact with

an enterprise application integration (EAI) layer, an ESB such as IBM WebSphere Message Broker or

IBM WebSphere Process Server. The ESB can then handle the distribution of incoming documents to one

or more internal applications using either WebSphere adapters or mediation handlers. If an incoming

document needs to be delivered to only one application, WebSphere Partner Gateway can interact with that

application directly.

Figure 3: IBM WebSphere Partner Gateway extending the reach of integration

However, if a document needs to be delivered to more than one internal application based on the content

or the document type, using an ESB greatly simplifies the overall infrastructure. Several connection options

can be used to integrate WebSphere Partner Gateway and ESB servers. When the documents are sent to a

back-end application, detailed metadata can be exchanged over transport headers, which helps in building

flexible solutions.


Another type of integration is available through the transformation engine, especially with EDI

translators such as IBM WebSphere Data Interchange and IBM WebSphere Transformation Extender.

Documents can be transformed within WebSphere Partner Gateway or at the ESB level. WebSphere Partner

Gateway can validate and generate functional acknowledgments and use a transformation engine to

transform XML and other document formats. These transformed documents are then delivered to internal

applications.

B2B Integration empowered by SOA and BPM is the future ofmultienterprise integrationB2B Integration with BPM and SOA is a primary consideration for many multienterprise integration

implementations today, and it will continue to evolve. IBM sees business, IT alignment and business model

innovation as the most important aspects of an enterprise strategy. A need for B2B transaction visibility,

processing and ability to monitor in real time and take rapid actions are requirements now and will

continue to be critical for multienterprise integration environments. This enables B2B Integration to

become a core part of any enterprise’s platform for BPM, business activity monitoring (BAM), application

integration (AI) and SOA.

WebSphere Partner Gateway is based on a highly scalable SOA infrastructure for BPM, leveraging

IBM WebSphere Application Server and integrating with complementary functions in WebSphere and other

platforms. WebSphere Partner Gateway uses WebSphere Application Server Network Deployment to support

consolidated application management—with existing investments, for Web services, and throughout the

BPM and SOA infrastructure. For an overview of the functions provided by SOA, see Figure 4.

The SOA architecture below depicts how partner services are critical to an SOA platform and how and

where it can be integrated into the overall infrastructure.


Figure 4: B2B as Partner Services is a Critical Component in SOA Architecture

WebSphere Partner Gateway is based on physical component architecture with multiple deployment

options—providing high throughput, near linear scalability and many high-availability options. Multiple

instances of specific B2B gateway components (such as receivers, gateways, document managers,

community consoles and so on) can be dynamically installed and configured on multiple servers

(and dynamically decommissioned) to support rapidly changing or unpredictable scalability and throughput

requirements.


WebSphere Partner Gateway integrates with the WebSphere SOA infrastructure for business process

management, extending the reach of BPM solutions to secure B2B transactions with trading partners.

WebSphere Partner Gateway supports related middleware services in the IBM Software Group portfolio,

including IBM WebSphere Transformation Extender, IBM WebSphere Data Interchange, IBM WebSphere

DataPower® SOA Appliances, IBM WebSphere MQ, IBM WebSphere Process Server, IBM WebSphere

Business Monitor, IBM Lotus® Forms and IBM WebSphere Application Server.

WebSphere Partner Gateway supports BAM by using the Common Base Event specification to format

events about B2B transactions and then delivering these events to WebSphere Business Monitor,

IBM Tivoli® Monitoring and other third-party monitoring environments. WebSphere Partner Gateway

comes with over 300 ready-to-use Common Base Event definitions for technical and business B2B events,

and it allows users to create their own custom events. These events can be used today with Tivoli

Monitoring for IT-level problem resolution as well as with WebSphere Business Monitor for business

activity monitoring—through business-level dashboards used by line-of-business (LOB) executives and

other LOB professionals.

IBM WebSphere Partner Gateway provides a complete B2B environment that is created by the

intersection of B2B, SOA and BPM capabilities, as shown in Figure 3.

Example of an innovative approach for B2B integration that enablesflexibility and reduces cost: TradeMerit leveraging WebSphere PartnerGateway for Supply Chain Management – Software as ServicesSolutionTradeMerit is a global international trade and logistics services company providing visibility solutions for

enterprises and their partners into their supply chains. TradeMerit’s solutions provide proactive supply-

chain event management, trade planning and supply chain analytics, and performance analysis. The

company delivers on-demand, business-focused solutions that allow users to effectively manage, thoroughly

plan and accurately measure performance in their supply chains.

TradeMerit’s customers faced many business problems, including:

● Uncertain trade-lane delivery

● Excessive buffer inventory

● Expedited deliveries and premium transportation costs

● Compliance penalties

● Costly manual interventions

● Risky change and optimization

These pain points are felt in a business environment that is highly competitive, with demanding customers,

government regulations, resource constraints, diminishing time to action and lower margins.

TradeMerit’s challenge was to find a highly functional and proven solution to offer supply chain

management to its customers. The solution needed to be highly adaptable and to provide BAM, process

management and B2B functions—all built upon an SOA foundation for the greatest flexibility and lowest

cost deployment. A proven solution with the ability to be operative quickly was very important to

TradeMerit, because this technology would be an asset for a company that makes software services the core

of its business. Because change and evolution is expected for the company’s future growth, TradeMerit

needed its SOA foundation to be highly adaptable and scalable while providing a foundation for the

deployment of new business solutions.


TradeMerit, an IBM business partner, took less than one year to move from solution investigation and

selection to solution deployment. This speed was necessary for TradeMerit, a start-up company, to get a

solution to market quickly. The speed in which the solution was deployed was also a testimony to the

strength, ease of use and functional richness of IBM technology. IBM was chosen over Microsoft® and

other competitive best-of-breed solutions—such as BEA, Tibco, Oracle and SAP—because the

IBM WebSphere portfolio was the most complete, well integrated and easiest to deploy. TradeMerit

needed software that met its requirements with no need for customization.

TradeMerit offers supply chain management (SCM) capability as a software service to its customers along

with browser-based dashboards and analytic capability.

Figure 6: Sample B2B solution implemented by TradeMerit

As shown in Figure 4, TradeMerit monitors events in the supply chain through IBM WebSphere Partner

Gateway. These events can be in various media and formats including FAX, EDI and messages. TradeMerit

noted that the IBM solution was much more sophisticated than a traditional EDI messaging infrastructure.

This meant TradeMerit’s solution development was simpler and less prone to error. As a result, TradeMerit

could offer its customers a solution that was functionally richer at less cost. Events are passed to


IBM WebSphere ESB for mediation and routing and on to IBM WebSphere Process Server.

IBM WebSphere Process Server then manages the flow of information and, with IBM WebSphere

Business Monitor, the software performs event correlation and analysis, implements rules, generates alerts

and measures various key performance indicators (KPIs). TradeMerit’s customers can then view various

KPIs and alerts in a browser, using a dashboard that TradeMerit offers as a service to its customers.

IBM WebSphere Business Modeler and IBM WebSphere Integration Developer are the tools used to

construct the various process flows, KPIs and executable programs. TradeMerit’s customers can then

modify alerts and rules and analyze alternate scenarios using the data provided and the dashboard.

During each phase of the supply chain, customers can complete various tasks using the dashboard

provided by TradeMerit:

● Plan— Establish trade agreements and shipping plans— Set up KPIs— Set up operational targets

● Identify operational rules● Collaborate

— Identify key supply-chain members— Identify compliance and other certification— Identify communication channels (EDI, XML, paper and others)

● Measure— Detect exceptions and trigger resolution process— Provide real-time performance measurements— Monitor dashboards and scorecards

● Optimize— Create alternative scenarios— Analyze the cost and impact of implementing each scenario— Optimize the current supply-chain model to reflect new findings


The IBM solution is the core technology of TradeMerit as a business and delivers the following benefits:

● WebSphere software helped TradeMerit maintain a very aggressive development schedule.

● WebSphere software provides an SOA foundation upon which to build new services and evolve offeringswithout discarding what has already been built.

● Functional richness meant that valuable development effort could be spent on solution delivery versusbuilding infrastructure or middleware services. This richness also reduced complexity, because thecomplexity of the middleware was contained in the IBM software.

● WebSphere software delivered a highly scalable solution, which is critical for a growing company.

● WebSphere BPM proved to be consumable and rich in function for a small company.

SummaryB2B integration is evolving and becoming an integral part of the business strategy for most of the

enterprises as they grow their ecosystem with partners and customers. The increasing demand for business

and IT alignment is driving a critical requirement for end-to-end value chain management and visibility.

This requirement fuels multienterprise integration needs beyond the applications and data used by the

processes. As a result, B2B technology must leverage SOA and BPM. Multienterprise integration

capabilities that leverage BPM, BAM and SOA provide the most advanced capabilities to enable IT users

and business users to overcome the challenges of B2B integration.

IBM WebSphere Partner Gateway, an industry-leading B2B gateway software offering, enables greater

flexibility, faster time to value, lower maintenance cost and strong ROI by providing:

● Centralized and secure B2B trading-partner and transaction management

● Extensive support for data formats, protocols and industry standards

● Extensibility framework to support the integration of third-party applications

● Component architecture for high scalability, throughput and availability

● The ability to leverage WebSphere Application Server NetworkDeployment and its capabilities

● Business activity or process monitoring through events formatted using theCommon Base Event standard

● Integration with SOA and BPM capabilities
