Xpress Transport Protocol <networking, 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. XTP Home (http://ca.sandia.gov/xtp/). Contrast with {Transmission Control Protocol}. XTP does not employ {congestion} avoidance {algorithms}. (2003-03-22)
