This combination is often known as a socket address. It is therefore often also called Internet socket.Īn application can communicate with a remote process by exchanging data with TCP/IP by knowing the combination of protocol type, IP address, and port number. In practice, due to the proliferation of the TCP/IP protocols in use on the Internet, the term network socket usually refers to use with the Internet Protocol (IP). Network sockets may be dedicated for persistent connections for communication between two nodes, or they may participate in connectionless and multicast communications. They are used as service types, and, once created by a process, serve as an externally (from the network) addressable location component, so that other hosts may establish connections.

Ports are numbered resources that represent another type of software structure of the node. It is stored by the application process for use with every read and write operation on the communication channel.Īt the time of creation with the API, a network socket is bound to the combination of a type of network protocol to be used for transmissions, a network address of the host, and a port number. In Unix-like operating systems, this descriptor is a type of file descriptor. The application programming interface (API) for the network protocol stack creates a handle for each socket created by an application, commonly referred to as a socket descriptor. Similarly, the term port is used for external physical endpoints at a node or device. The use of the term socket in software is analogous to the function of an electrical female connector, a device in hardware for communication between nodes interconnected with an electrical cable.
The term socket is also used for the software endpoint of node-internal inter-process communication (IPC), which often uses the same API as a network socket. In this context, a socket is externally identified to other hosts by its socket address, which is the triad of transport protocol, IP address, and port number. Sockets are created only during the lifetime of a process of an application running in the node.īecause of the standardization of the TCP/IP protocols in the development of the Internet, the term network socket is most commonly used in the context of the Internet protocol suite, and is therefore often also referred to as Internet socket. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
