Abstract: PROBLEM TO BE SOLVED: To manage multimedia contents and a resource by managing the number and positioning of replicas related with an object in an internet/Web environment so as to make use of unique characteristics. SOLUTION: An intermediate controller receives requests 601 to 604 including a characteristics object ID from a client and sends them to a positioning module 610 from a request processing module 600. The module 610 applies a positioning policy 615 to the respective requests to generate a set of a temporary positioning inquiry 620 concerning the requests. The module 610, a replica directory service 665 and a replica directory 666 cooperatively find all the replicas related by the object ID of a received request. Further, the module 610, a server directory service 655 and a server directory 656 cooperatively judge the intention of a position for considering the new inquiry 620.

Abstract: A system providing access to web objects that matches predicted demand for web objects to available capacity on web servers. The system implements methods to dynamically shape both demand and capacity based on certain criteria. The system provides methods to dynamically shape demand for an object based on criteria such as arrival time, incoming geography, and costs requirements. In particular, the present invention characterizes future demand for an object based on aggregation and forecasting of past demand for such object. The system effectively permits control and customization of capacity across one or more media servers based on characteristics associated with the demand across one or more of them, and particularly, based on the dominating geographical traits of past demand. Moreover, the system dynamically shapes capacity by: (a) controlling the number of replicas associated with an object; and, (b) controlling the placement of these replicas across servers in a distributed network. In particular, the system drives capacity shaping measures over a particular object based on its predicted demand. Consequently, the number and location of replicas associated with an object is made to be variable over time and driven by predicted demand for a web object.

Abstract: A system and method for configuring service-oriented resources suitable for the resource management in a media server and more particularly, for resource configuration across distributed media servers. Heterogeneous media serves are configured in terms of homogeneous service-oriented resource units each used to represent a resource allocation commitment from a participating server for provisioning a particular media service on demand. A service unit associated with each different service supported by a media server represents an envelope of resource requirements as needed for provisioning a service. The method includes generating a resource envelope, and additionally compensating, at a media server, for differences between true resource utilization and resource envelope projected by a service unit. Each service unit also comprises a signature representing metadata used to control access to a service unit by defining rights, privileges, and characteristics of services that may use that particular server unit.

Abstract: 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.
