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.
