BSD Sockets Concepts Introduction binding channel communication domain internet address message packet peer port protocols socket Before a socket can be accessed across the network, it must be bound to an address. Binding associates a socket address with a socket and makes the socket accessible to other sockets on the network. Once a socket address is bound, other sockets can connect to the socket and send data to or receive data from it. Communication path created by establishing a connection between sockets. A set of properties that describes the characteristics of processes communicating through sockets. The internet (AF_INET) address family domain is supported. The UNIX Domain (AF_UNIX) address family domain is also supported, for local communication only. A four-byte address that identifies a node on the network. The data sent in one UDP packet. A message or data unit that is transmitted between communicating processes. The remote process with which a process communicates. An address within a host that is used to differentiate between multiple sockets with the same internet address. You can use port address values 1024 through 65535. (Port addresses 1 through 1023 are reserved for the super-user.) Two internet transport layer protocols can be used with BSD Sockets. They are TCP, which implements stream sockets, and UDP, which implements datagram sockets. Sockets are communication endpoints. A pair of connected sockets provides an interface similar to that of HP-UX pipes. A socket is identified by a socket descriptor. 18 Chapter 1
