Selection of TCP and UDP

answer203

The real-time performance of the battle platform is high, and occasional packet loss is acceptable, so it is definitely more appropriate to use udp. If tcp is used, then either the client and each client establish a TCP connection (regardless of the internal network) Either the server establishes a connection with each client and forwards the packets of each client. These two methods are different. How can udp bind a local port to receive packets from different sources?
