A system and method for configuring service-oriented resources is suitable for the resource management in a media server and more particularly, for resource configuration across distributed media servers, expected to be useful and suitable for the next generation of the Internet where, due to virtual proximity, resources are made to appear to be abundant by efficiently managing scattered resources from around the globe. In particular, heterogeneous media servers are configured in terms of homogeneous service-oriented resource units referred to as service units. The service unit is used to represent a resource allocation commitment (as opposed to a resource reservation) from a participating server to be able to provision a particular media service on demand. A service unit is associated with each different service supported by a media server and represents an envelope of resource requirements as needed for provisioning of such service. The method includes generating such a resource envelope, and additionally compensating, at a media server, for differences between true resource utilization and resource envelope projected by a service unit. Additionally, each service unit is associated with a signature which represents metadata used to control access to a service unit by defining rights, privileges, and characteristics of services that can use that particular server unit. The signatures are enforced at the media server. |
