A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
After instantiating a new socket, the server binds the socket to an address. For a Unix domain socket, the address is a /path/filename.. Because the socket address may be either a /path/filename or an IP_address:Port_number, the socket application programming interface requires the address to first be set into a structure.
Sockets provide means for programming TTA processors by allowing to select which bus-to-port connections of the socket are enabled at any time instant. Thus, data transports taking place in a clock cycle can be programmed by defining the source and destination socket/port connection to be enabled for each bus.
The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation.It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space.
Berkeley sockets originated with the 4.2BSD Unix operating system, released in 1983, as a programming interface.Not until 1989, however, could the University of California, Berkeley release versions of the operating system and networking library free from the licensing constraints of AT&T Corporation's proprietary Unix.
Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface (API). Examples of the connection-oriented protocols include Transmission Control Protocol (TCP) and Sequenced Packet Exchange (SPX), and examples of connectionless protocols include User ...

However, it was clear at least since the early 1990s that the Berkeley Socket interface would ultimately prevail. [4] TLI and XTI are still supported in SVR4-derived operating systems and operating systems conforming to branded UNIX (UNIX 95, UNIX 98 and UNIX 03 Single UNIX Specifications) such as Solaris and AIX (as well as the classic Mac OS ...
