Connected UDP sockets can also be used to determine out-of-office interfaces for a specific destination. This is caused by a side effect of the Connect function applied to the UDP socket: The kernel chooses the local IP address. This local IP

Now we look at the impact of UDP on datagram transmission without any traffic control. First we modify the DG_CLI function to send a fixed number of datagrams and no longer read from the standard input. As follows, it writes 2000 UDP datagrams of 140

We mentioned in the previous article that asynchronous errors are not returned to a UDP socket unless the socket is connected. We can actually call connect for the UDP socket, but the result is quite different from the TCP connection: no three

This function provides an iterative server, rather than providing a concurrent server as a TCP server. There is no call to fork, so a single server process has to deal with all customers. In general, most TCP servers are concurrent, and most UDP

Introduced As you enter the mysterious World of Unix, you will soon find that more and more things are hard to understand. For most people, the BSD socket is one of the concepts. This is a short tutorial to explain what they are, how they work and
