Embodiment Construction
[0011] First, obtain a data network composed of a switch and multiple terminals, each terminal uses the same protocol as the switch for data transmission. First initialize the network hardware of each terminal and switch. After the network physical interface layer of each device works normally, use reliability monitoring at the network layer and transport layer of each device. The monitoring method is specifically written to monitor between the network layer and the transport layer. The function here is defined as the monitoring function A, which is used to monitor the multicast inquiry from the central node.
[0012] Let the monitoring function A be
[0013] (…
[0014] / *Send multicast data* /
[0015] / *Monitor network layer and transport layer function end* /
[0016] / *Monitor the group addition query of the multicast protocol* / / *Monitor the version of the multicast protocol* /
[0017] / *When it is judged that it is IGMPV3 with source group information plus group query*...
