The Admission Control component Web service establishes a configurable threshold for the number of requests from Web service implementations which are admitted into the system (server and cluster level), within a given time interval.
Immediately upon receipt of a Web service request, service implementation logic invokes the Admission Control component Web service to determine whether to accept or reject the request from the Web service clients.
If the request is accepted, processing continues as normal.
If the request is rejected, the Admission Control component Web service returns an error message to the requester.
This component enables you to control how much traffic can be accepted by each service for each member of the cluster and across the cluster. Controlling traffic helps ensure that in the event of a prohibitively large number of requests, servers do not exceed planned capacity.
