In section c #, we discussed the reliable transmission of udp packets (packet group transmission). However, the problem with the previous program is that the data is relatively large, A Message class has 2048B after serialization, and the actual data volume is only 50B, which indicates that the data is very effective. In this way, when too many packets are transmitted, the efficiency will be greatly reduced. Therefore, we only need to find a way to re
