Sample text

5. 5. UDP Attributes 65,535 (65,507 max data payload) 28–68 Low One-shot Medium Medium Yes Each layer up the IP stack provides more focus on data and less on the network. UDP hides some of the details about error messages and how the kernel transmits messages. Also, it reassembles a fragmented message. A message you send via UDP is like an email message: The destination, origin, and data are all the information it needs. The kernel takes the message and drops it on the network but does not verify its arrival.

Only diagnostic or routing programs use this option. MSG_DONTWAIT Don't wait for send() to finish. This option allows the program to proceed as if the send() were done (or delegated). If used, the operating system issues a SIGIO signal, indicating a completed write() operation. If the operation blocks because the send() queue is full, the call returns an error and sets errno to EAGAIN. MSG_NOSIGNAL Don't issue a SIGPIPE signal. If the other end closes early, and if your program sends another message, your may get a SIGPIPE signal.

TCP Attributes (unlimited) 40–120 High (data receipt checked) Stream Low (compared to other protocols) High (includes checksums) Unlikely Taking reliability one step further requires ensuring that the destination gets the exact message the originator sent. UDP has the speed but does not have the reliability that many programs require. TCP solves the reliability problem. The network, however, has several fundamental problems that make it unreliable. These problems are not limitations. Instead, they are inherent in the design of the network.
