Method and network for interconnecting separate multicast channels acquired for separate bus systems

摘要

In a communication network where multiple bus systems are interconnected by a bus bridge, a first node attached to a first bus system acquires a first channel for transmission of packets to a first multicast address and broadcasts a first message pertaining to the first channel and the first multicast address. A second node attached to a second bus system acquires a second channel for transmission of packets to a second multicast address and broadcasts a second message pertaining to the second channel and the second multicast address. In response to receipt of the first and second messages, the bus bridge establishes a connection between two channels respectively identified by the received messages if the multicast addresses contained in the received messages are equal to each other.
