Xpress Transport Protocol
     
         (XTP) A {transport layer} {protocol}
        for high-speed networks promoted by the {XTP Forum}.  XTP
        provides protocol options for error control, {flow control},
        and rate control.  Instead of separate protocols for each type
        of communication, XTP controls {packet} exchange patterns to
        produce different models, e.g. reliable {datagrams},
        {transactions}, unreliable {streams}, and reliable {multicast}
        connections.

        Contrast with {Transmission Control Protocol}.  XTP does not
        employ {congestion} avoidance {algorithms}.
