The Free On-line Dictionary of Computing (30 December 2018):

connection-oriented
stream-oriented

    (Or connection-based, stream-oriented).  A type of
   transport layer data communication service that allows a host
   to send data in a continuous stream to another host.  The
   transport service will guarantee that all data will be delivered
   to the other end in the same order as sent and without
   duplication.  Communication proceeds through three well-defined
   phases: connection establishment, data transfer, connection
   release.  The most common example is Transmission Control
   Protocol (TCP), another is ATM.

   The network nodes at either end needs to inform all intermediate
   nodes about their service requirements and traffic parameters in
   order to establish communication.

   Opposite of connectionless, datagram.  See also circuit
   switching, packet switching, virtual circuit.
