Abstract
The present invention concerns a method and apparatus for memory and channel sharing in a communication switching network which uses packet switching. In one form of the invention memory and channel sharing is provided within a packet switch. The packet switch includes a memory for storing a plurality data packets and a router that routes data packets from the memory to a particular output port. The router is operable to route data packets to either a dedicated output port, in other words, an output port defined by the virtual circuit path of the data packet, or a shared output port. In another form of the invention memory and channel sharing is provided by a packet switch in conjunction with a terminal. Protection lines which are provided in transmission systems can be used as the shared channels.
