The Telecom Web Services Access Gateway provides policy-driven traffic monitoring, message capture, authorization, and management capabilities. These services are provided at the application layer, and is enforced for each Web service request using knowledge of the requester, target service, and invoked operation.
The Access Gateway provides flexibility for the construction of tailored message processing logic, in accordance with your enterprise's network policies. This logic can be customized to meet your network requirements.
All Web service requests and responses pass through and are inspected by the Access Gateway. It acts as an intermediary for all communications between client and service endpoints by processing both incoming and outgoing requests. Mediation primitives within the Access Gateway have access to the SOAP message in its entirety in the form of a Service Message Object (SMO), including headers and body. This allows mediation primitives to determine the initiating requester, target service, and invoked operation. In addition, policy data is passed between mediation primitives in the form of additional XML elements within the SOAP header.
The Access Gateway extends WebSphere® ESB by adding policy-driven processing elements and new components to monitor Web service traffic. Using WID tooling, you can model your network policies, enable new features, and deploy customized logic into the Access Gateway.
