| 摘要 |
The present invention relates to a communications network having a number of network domains (1, 2, 3, 4) operating in accordance with respective communications protocols and a number of bridges (5, 6, 7) for interconnecting the network domains. Each bridge includes a number of interconnectable ports for coupling to the network domains, and a processor adapted to communicate with other bridges (5, 6, 7) on the network to allow an optimum path between domains to be determined. The optimum path is determined in accordance with path cost components which represent the ability of respective ports to transfer data.
