WebSphere WebSphere Enterprise Service Bus, Version 6.0.1 Operating Systems: AIX, HP-UX, Linux, Solaris, Windows

Service requesters and providers

In an enterprise service bus, applications that require the services of another application are known as service requesters. Correspondingly applications which offer services are called service providers.

A service requester might send a service request over the bus.

When it receives the request, a service provider runs the requested service.

The service provider might also send a reply back through the bus to the requester.

Figure 1. A service requester sending a request over the ESB. The enterprise service bus passes the request to a service provider. The service provider runs the requested service then, optionally, sends a reply to the requester.

The WebSphere ESB can interconnect a variety of different requesters and providers using standard protocols including:

For common applications (such as SAP) and other protocols, IBM WebSphere Adapters as well as other industry-standard J2C Adapters, are available.

WebSphere ESB supports diverse messaging interaction models to meet your requirements, including the following models:
