Abstract
An arbitration switching system and a method of arbitration switching in a high-speed packet switching system uses a subscriber input/output device, an arbitration switching system and a parallel common bus part for the purpose of point-to-point communication point-to-multipoint communication and transferring packets generated in each node. A system bus structure is based on a parallel common bus type. Furthermore, to accommodate high-speed arbitration switching, operations such as polling, arbitration and switching are processed in parallel. Therefore, bus use efficiency is high, and a bus-extension can be easily achieved. A star LAN may be realized because broadcasting and multicasting are supported. An internal high-speed network for interlock in large-scaled communication systems that need high-speed switching can also be provided.
