The Sockets Direct Protocol SDP is a networking protocol originally defined by the Software Working Group SWG of the InfiniBand Trade Association . Originally designed for InfiniBand IB ref ANNEX A4 SOCKETS DIRECT PROTOCOL SDP . In InfiniBand Architecture Release 1.2.1 , p. 1215ff. PDF download from http www.infinibandta.org content pages.php?pg technology download InfiniBand Trade Association , accessed October 2011 ref , SDP now has been redefined as a transport agnostic protocol for Remote Direct Memory Access RDMA network fabrics. SDP defines a standard wire protocol over an RDMA fabric to support stream sockets SOCK STREAM . SDP uses various RDMA network features for high performance zero copy data transfers. SDP is a pure wire protocol level specification and does not go into any socket API or implementation specifics. The purpose of the Sockets Direct Protocol is to provide an RDMA accelerated alternative to the Transmission Control Protocol TCP protocol on Internet Protocol IP . The goal is to do this in a manner which is transparent to the application. Today, Sockets Direct Protocol for the Linux operating system is part of the OpenFabrics Enterprise Distribution OFED , a collection of RDMA networking protocols for the Linux operating system.

Unreferenced date December 2009 Orphan date December 2008 correct title AF INET In computer networking , programmer s using Berkeley sockets use AF INET to represent the address family INET for Internet socket s, meaning the IPv4 protocol as opposed to AF INET6 for IPv6 sockets, PF UNIX for Unix domain socket s and so on . Moreover, AF INET Address Family sockets can be either connection oriented type SOCK STREAM or they can be connectionless type SOCK DGRAM . Connection oriented AF INET sockets use TCP as the transport protocol. Connectionless AF INET sockets use UDP as the transport protocol. When you create an AF INET domain socket, you specify AF INET for the address family in the socket program. AF INET sockets can also use a type of SOCK RAW. If this type is set, the application connects directly to the IP layer and does not use either the TCP or UDP transports http publib.boulder.ibm.com iseries v5r2 ic2928 index.htm?info rzab6 rzab6uafinet.htm . last access 29 April 2011.

Low insertion force sockets LIF are integrated circuit sockets that are designed so the force required to insert or remove a package is low. Initially, the LIF connectors were designed as a cheaper alternative compared to Zero insertion force ZIF connectors, to facilitate programming and testing of equipment. Compared with standard IC sockets, they have a lower friction force between the contacts of the device and the socket, making insertion and removal of the device easier, while at the same time eliminating the need for the complex mechanism that is used in ZIF sockets. The disadvantages of LIF connectors are that the grip force between the contacts is lower, and the contacts can oxidize faster and decrease the lifespan of the connector. With the advent of frequent changes in PC processors, a need arose for these systems. Intel introduced the LIF socket system, in which the processor is inserted into the socket, rather than fixed by a lever. This type of socket was used for some types of 386s and early 486s. This type of socket has been replaced by the zero insertion force ZIF socket, although LIF sockets are now used in modern 1.8 hard disks.

Computer network programming involves writing computer programs that enable process computing processes to communicate with each other across a computer network . Network programming is client server programming main client server model Interprocess communication , even if it is bidirectional, cannot be implemented in a perfectly symmetric way to establish a communication channel between two processes, one process must take the initiative, while the other is waiting for it. Therefore, network programming unavoidably assumes a client server model The process initiating the communication is a client computing client , and the process waiting for the communication to be initiated is a Server computing server . The client and server processes together form a distributed system . In a peer to peer communication, the program can act both as a client and a server. Network programming is socket programming main Network socket The endpoint in an interprocess communication is called a socket, or a network socket for disambiguation. Since most communication between computers is based on the Internet Protocol, an almost equivalent term is Internet socket . The data transmission between two sockets is organised by communications protocol s, usually implemented in the operating system of the participating computers. Application programs write to and read from these sockets. Therefore, network programming is essentially socket programming. Standard API main Berkeley socket The reference application programming interface for socket programming is the Berkeley sockets Berkeley or BSD sockets API , first introduced in 1983, which has evolved into a POSIX standard. Application programs create, control, and use sockets through system calls like code socket code , code bind code , code listen code , code connect code , code send code , code recv code .
