摘要 |
A border network device for transmitting messages between a first multicast domain and a second multicast domain includes a first interface that receives a first domain message from the first domain for delivery to the second domain, a first message converter that converts the received first domain message into a first intermediate message, and an output that forwards the first intermediate message to a receiving second network device in the second domain. The first multicast domain and second multicast domain each respectively have first network devices and second network devices. In preferred embodiments, the first domain message has first domain origin data. Messages with first domain origin data originate from at least one of the first network devices. In a similar manner, the intermediate message includes intermediate data indicating that the intermediate message originated from the border network device. |
