Abstract
A SMDS (Switched Multi-megabit Digital Service) switching apparatus provides connectionless-mode high-speed digital data switching services suitable for use in connection between telecommunication terminals, e.g. LANs (Local Area Networks) via a network. The SMDS switching apparatus is formed of plural subscriber's circuits, each of the plural subscriber's circuits accommodating at least one subscriber's terminal; an automatic routing selection switch connected to the plural subscriber's circuits, the automatic routing selection switch receiving a fixed length cell formed of a logic channel information portion and a data portion and selecting automatically an output route for the fixed-length cell, based on information in the logic channel information portion; and an analyzing unit receiving a fixed-length cell sent from the automatic routing selection switch and then analyzing sender information and receiver information each regarding the fixed-length cell. The object is to provide a SMDS switching apparatus wherein an arrival-site processing unit executes the routing procedure in an originating-site processing unit to suppress an increase in the capacity of the routing table.
