In computer operating systems, a stream socket is a type of interprocess communications socket or network socket which provides a connection-oriented, sequenced, and unique flow of data without record boundaries, with well-defined mechanisms for creating and destroying connections and for detecting errors.
A stream socket transmits data reliably, in order, and with out-of-band capabilities.
On the Internet, stream sockets are typically implemented on top of TCP so that applications can run across any networks using TCP/IP protocol. SCTP may also be used for stream sockets.
