Abstract
A packet-based communication system comprises first and second endpoints, an application manager and a policy server. When establishing a connection between the endpoints the application manager sends, to the policy server, application control related information about the required connection. The policy server then selects at least one application control parameter, such as a codec to be used by the endpoints, and returns this information to the application manager. The application control information can be carried between the application manager and policy server by an application control protocol, such as the Session Initiation Protocol (SIP), or by modified forms of policy control protocols such as the Common Open Policy Service (COPS), Diameter, SOAP/XML or Parlay.
