Abstract

An open, high speed, high bandwidth digital communication network for connecting multiple programmable telecommunications switches to form a large capacity, non-blocking switching system. Each network switching node includes circuitry for transmitting and receiving variable-length, packetized information over the network, thus enabling each node to receive information from or transmit information to all other nodes. The network may carry any type of information present in the system including voice, data, video, multimedia, control, configuration and maintenance, and the bandwith of the network may be divided or shared across various information types. Devices such as voice processing resources may also interface with the network, thereby gaining direct access to all information passing through the network. Also provided are methods and packet structures for communicating information over the network. Multiple networks may be interconnected to provide even greater switching capacity or voice processing capacity.
