ABSTRACT:
An architecture for a switching node of a communication network includes a dedicated hardware Layer 1 processing portion and a Layer 2 and 3 processing portion based on multiple programmed general purpose processors. An array of such processors are used with an arbitration scheme for selecting which of the processors is to be used for any given Layer 2 or Layer 3 process. The architecture allows the node's capacity to be expanded by simply adding more processors to handle increased traffic.
