Sequenced Packet Sockets − They are really just like a stream socket, with the exception that record boundaries are preserved. This interface is supplied only as a Element of the Network Methods (NS) socket abstraction, and is critical in the majority of significant NS applications. Sequenced-packet sockets allow the person to control the Sequence Packet Protocol (SPP) or Web Datagram Protocol (IDP) headers over a packet or a gaggle of packets, both by crafting a prototype header in conjunction with whatsoever information will be to be sent, or by specifying a default header to be used with all outgoing data, and makes it possible for the person to receive the headers on incoming packets.

The applying programming interface (API) that courses use to talk to the protocol stack, applying community sockets, is referred to as a socket API. Enhancement of software applications that use this API is known as socket programming or network programming. World-wide-web socket APIs are usually based on the Berkeley sockets conventional.
