Abstract
A multi-media file system for conmmunicating information between a multi-media client and a network storage device over a network. The file system includes a cluster that comprises one cluster manager and at least one file manager with each network storage device. The cluster manager is located on a client, includes an admission controller for controlling the admission of a request from a client for a file operation upon a selected file. A network bandwidth request from the admission controller is responded to by a network status determiner included in the cluster manager. The network status determiner determines the available network bandwidth. Each file manager is located on one of the clients. The file managers manage file maintenance procedures of corresponding files located on the network storage device. Each file manager includes a disk status determiner for determining the available disk bandwidth. The disk status determiner responds to a request from the admission controller.
