A data service system is accessible through a plurality of access requests. The data service system includes a user access request classification system for classifying the access requests. The user access request classification system includes a request classifier that classifies each of the access requests into one of a plurality of classes based on a predetermined classification policy. The user access request classification system also includes a plurality of buffers coupled to the request classifier. Each buffer corresponds to one of the classes to receive the access requests classified by the request classifier as belonging to that class such that the data service system processes the access requests in accordance with their classes. A method of classifying user access requests for the data service system is also described.

Method and systems for allowing data service system to provide class-based services to its users

A data service system is described that includes a plurality of data content sites and is coupled to a number of user terminals via a network. The data service system also includes a system for providing performance guarantees for the content sites. The system for providing performance guarantees includes a plurality of class processors, each for controlling access throughput of one of the content sites in accordance with a predetermined admission control policy. When one of the class processors receives an access request for one of the content sites, that class processor determines if the access request should be accepted based on the corresponding admission control policy and sends the access request to the corresponding content site when accepting the access request. The system also includes a classifier that determines to which one of the class processors the access request should be sent. A method of controlling access throughput of the content sites is also described.
