Abstract
In accordance with the present invention, there is provided a multi-port bridge where problems in conventional virtual bridging are solved, and especially a multi-port bridge which can be managed with a program that manages only two-port bridges. The multi-port bridge comprises, in terms of hardware, one adapter such a TRN adapter 70 connected to one port 50, other adapters such as other ISDN adapters 71 to 77 connected to a plurality of other ports 51 to 57, and processor 86 for providing virtual bridges and a virtual Token-Ring between one adapter and other adapters. Processor 86 provides by means of a program a virtual bridge module 120 having a bridging function to TRN adapter 70 connected to one port 50, and virtual bridge modules 121 to 127 having a bridging function to other ISDN adapters 71 to 77 connected to ports 51 to 57, respectively. Further, processor 86 provides by means of the program virtual Token-Ring module 128 for coupling these virtual bridge modules 121 to 127.
