Originally, it can send and receive data for a host to join a multicast group. The specific processing of data can be implemented by multicast router. But now there is a question, please teach. In a local area network, a HUB is connected to a few PCs, there is no multicast router, what do I want to implement multicast features? I have read a lot of articles to handle multicast in a way using broadcasting. This method refers to the local area network is already doing this. It is the multicast application to work properly) or can we write programs in this way? If this method does not use this method, what should I write a maintenance multicast routing table? How should the original IGMP Report be implemented? Does anyone have ready-made programs?
Another way is to apply layers multicast, such as sending audio data through RTP, how can you make multicast features to RTP? Thank you!
