7. UDP In the most common sense, the so-called UDP is a network protocol that does not matter when it is sent out. Therefore, the sending end of UDP programming only needs to send, and the network connection status does not need to be checked. The

An example shows the relationship between the sending buffer, the receiving buffer, and the sliding window protocol. In the previous articles, I briefly introduced the relationship between the above concepts in TCP network programming and the

When the socket sends data, it first sends the data to the socket buffer, and then receives the function to retrieve the data from the buffer. If the sending end is particularly fast, the buffer will soon be filled up (the default socket is 1024 × 8

[Requirement]Checks whether the client program is forcibly terminated without affecting server processing.[Status quo]The keepalive attribute is set for both the server and client sockets.The server sets parameters such as the number of probes. The

The problem with binding (BIND) ports mentions that a network application can only bind to one port (one socket can only bind one port).In fact, by default, if a socket for a network application is bound to a port (8000), the port (8000) cannot be

Original link: http://blog.csdn.net/maopig/article/details/6982457The system provides a socket buffer size of 8K, which you can set to 64K, especially when transferring live video.When the socket sends the data to the socket buffer, then accepts the
