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.
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 ...

BSD was sponsored by DARPA until 1988, [3] which led to the implementation of ARPANET and later the TCP/IP stack to Unix by BSD, [4] which were released in BSD NET/1 in 1988. The codebase had been rewritten so much that as little as 5% of BSD contained original AT&T code, [4] and therefore NET/1 was released without an AT&T source license. [3]
Google developed Protocol Buffers for internal use and provided a code generator for multiple languages under an open-source license. The design goals for Protocol Buffers emphasized simplicity and performance. In particular, it was designed to be smaller and faster than XML. [3]
Internet Direct, also known as "Indy", is a free software / open source socket library written in Object Pascal, an object-oriented version of Pascal.It includes clients, servers, TCP, UDP, and raw sockets, as well as over 100 higher level protocols implementations such as SMTP, POP3, NNTP, and HTTP.

Netlink is a socket family used for inter-process communication (IPC) between both the kernel and userspace processes, and between different userspace processes, in a way similar to the Unix domain sockets available on certain Unix-like operating systems, including its original incarnation as a Linux kernel interface, as well as in the form of a later implementation on FreeBSD.

Multiple The Berkeley Packet Filter ( BPF ; also BSD Packet Filter , classic BPF or cBPF ) is a network tap and packet filter which permits computer network packets to be captured and filtered at the operating system level.
