How should TCP and UDP communication be chosen? For example, for the design of battle platforms, Hao Fang now uses the UDP forwarding mechanism. If TCP is used, will it cause network delay? Will it bring down experience and disconnection?

TCP provides reliable services. It ensures reliable transmission through technologies such as flow control, serial number, acknowledgment and timers, so there will be network delays in platforms such as battle and chat.

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?

However, according to the experiment, there may be a disconnection in the TCP forwarding through the server. This is very unclear.

Tcp cost is high, udp small data is superior
