High performance switch fabric element and switch systems

(57) The technique of link interconnection topology with a summary highly efficient switch fabric element and the adaptability for it and frame address specification is indicated. A fabric element can be set to ASIC of 16 ports equipped with the interconnection in which an internal steering is possible among all the ports. Since the port of a fabric element has the local routing table of a meaning respectively, there is no necessity for global routing table which is offered in a prior art. Thereby, since addressing and routing from a port to a port are possible without the necessity of carrying out lookup reference from the outside of a fabric element, within a fabric element, speed speeds up. Including concatenation, a ring, micro staging, and its combination, by a peculiar link interconnection technique, interconnection of the fabric element can be carried out and it can be used in parallel.
