Abstract
An initialization of local buses to , a definition of topology and a management of isochronous resources are performed for every local bus. Each of portals to includes an asynchronous packet discriminator which discriminates an asynchronous packet sent by a terminal device and transfers it. The portals to discriminate asynchronous packets sent by terminal devices in order to acquire isochronous resources and secure isochronous resources on different buses. The portals to transfer isochronous packets to different local buses by associating a received isochronous packet with a plug on the bridge bus side and a plug on the local bus side with an isochronous channel on the bus. Thus, the utilization efficiency of bus resource in a serial bus network is improved and a packet sent from a terminal device can be transferred to a different bus.
