Abstract

A Resource Management Framework (RMF) comprises an extensible, distributed, policy-based, object-oriented system and method for resource discovery and negotiation during the setup and control of a media session between one or more media servers and end users. The scope of the RMF framework is the management of multimedia resources used during simple, non-interactive as well as composite, complex, interactive multimedia sessions. The RMF enables iterative negotiated mapping over the requirements of an RMF-compliant application onto the offerings of one or more RMF-compliant media servers. It is an open-services architecture providing the ability to insert and apply services to enhance the suitability of offerings to requirements and vice versa, during a negotiated mapping session. Moreover, the RMF negotiated mapping algorithm itself is customizable via the use of policies (herein referred to as per-flow policies). The policies used to drive management decisions and service selections during these negotiated mapping are `pluggable`. New or updated policies may be added, to augment or replace an existing policy so as to realize new behavior or refine existing behavior.
