A reduced operation protocol engine (ROPE) for a multiple-layer bypass architecture

摘要: The Reduced Operation Protocol Engine (ROPE) presented here offloads critical functions of a multiple-layer protocol stack, based on the “bypass concept” fast path for data transfer. motivation identifying this separate processing is that it involves only small subset complete protocol, which can then be implemented in hardware. Multiple-layer bypass also eliminates some inter-layer operations such as queue and buffer management, context switching movement across layers, all are significant overhead. ROPE intended to support high-speed bulk paper describes design chip OSI Session Transport layer protocols, using VHDL. practical terms complexity area, current gate array technology, simulation shows rate approaching 1 gigabit per second, connection attached an end-system.
