Session Capacity- and Rate-based Admission Control

A session agent defines a signaling endpoint. It is a next hop signaling entity that can be configured to apply traffic shaping attributes. You can define concurrent session capacity and rate attributes for each session agent.

You can configure a set of attributes and constraints for each session agent to support session access control. In this configuration, the Oracle® Enterprise Session Border Controller only accepts requests from configured session agents. And you can set up session admission control so that the Oracle® Enterprise Session Border Controller limits the number of concurrent inbound and outbound sessions for any known service element.

The Oracle® Enterprise Session Border Controller denies a call request to any destination that has exceeded its configured policies for session capacity and session rate. The Oracle® Enterprise Session Border Controller might reject the call request back to the originator. If multiple destinations are available, the Oracle® Enterprise Session Border Controller will check current capacity and rate for each destination and attempt to route the call only to destinations whose policy limits have not been reached.

You assign a media profile to a session agent and indicate whether the transport protocol is SIP or H.323. If the protocol is H.323, you need to indicate whether the session agent is a gateway or a gatekeeper.
