ABSTRACT:
A multimedia system for delivering multimedia content items to customer premises equipment via a circuit of a communications network includes a plurality of substantially identical nodes connected in a symmetric mesh. Each node includes a switch and a server. The server includes disk storage for the multimedia content, a switch interface for connecting the server to the switch, and a network adapter for connecting the server to the communications network. Source nodes fetch data from disk, routing nodes transport data among nodes, and destination nodes transport the data to the communications network. The switch is a store-and-forward switch including direct memory access engine for pulling data into the switch, and a buffer for storing data to be forwarded to another switch. Portions of each content item are distributed substantially equally over the available storage media to improve load balancing and data redundancy.
