This book teaches readers how to program Linux sockets, and gives them everything they need to know to make programs communicate effetively over networks.

It presents a comprehensive discussion of all relevant topics including: writing programs compatible with both Internet Protocol version 4 (IPv4) and IPv6, raw sockets, User Datagram Protocol (UDP), broadcasting /multicasting, server internals, and more, plus a section covering Posix threads.

It provides thorough coverage of programming with the TCP, UDP, and IP protocols, as well as lower-level raw sockets. The myriad of function calls, data structures, and options associated with the APIs are explained with well-chosen diagrams and tables.
