Abstract: A system includes a policy repository configured to store a plurality of plurality of media-centric policies. A media policy decision point receives media session data corresponding to one of the plurality of media sessions; determines a plurality of media-specific and non-media specific attributes, based on the media session data; and evaluates a plurality of media-centric policies to determine a proper subset of the plurality of media-centric policies that apply to the one of the plurality of media sessions. A media policy enforcement point enforces the proper subset of the plurality of media-centric policies to control the one of the plurality of media sessions.

Abstract: A system includes a policy repository configured to store a plurality of media-centric policies. A media policy decision point is configured to execute operational instructions in accordance with a media centric policy language to select at least one of the plurality of policies corresponding to one of the plurality of media sessions based on, for example, feedback extracted monitoring the plurality of media sessions. The media-centric policy language, in various embodiments, expresses at least one of: operator preferences, operator goals, or operator constraints, facilitates management of individual ones of the plurality of media sessions and/or facilitates management of aggregate media traffic over the plurality of media sessions.

Abstract: Methods and apparatus for managing a media session on a network device, and for selecting and applying policies to the media session. The network device may initially evaluate a general set of media session policies. A subset of the policies may be identified by selecting only those policies whose rules are currently satisfied, or whose rules are not presently satisfied but which may be satisfied when a fast-changing characteristic of the media session changes. Policies whose rules are not initially satisfied due to a slow-changing characteristic are not likely to be satisfied within the life of the media session, and can be excluded from the subset of policies. Thereafter, only the subset of selected policies need be re-evaluated during the media session.
