基于矩阵判决的SCI/RT直接传输模式新方法
New SCI/RT immediate sending mode based on array judgment
【摘要】 对SCI/RT(scalable coherent interface for real time)TRAIN协议直接传输模式的分析表明,标准直接传输模式具有延迟小的特点,但其对环路带宽的利用率不高。为增加直接传输模式可用环路带宽,提高环路利用率,提出了基于矩阵判决的直接传输新方法。基于OPNET软件建立协议模型,通过不同场景和节点数环路的仿真对比,表明该方法较标准直接传输模式具有更好环路利用率;根据不同的数据包发送模式,直接传输模式可用带宽至少提高约25%;且算法在不同规模和配置的环路中均可使用。
【Abstract】 The immediate sending mode of SCI/RT TRAIN has lower transmission latency than arbitration mode,but with low ringlet usage ability.To improve ringlet transmission effective and get more ringlet usage rating,a new method based on load array is proposed.The SCI/RT ringlets with different nodes and different sending address modes are simulated by the OPNET software.Based on the simulation results,we prove that the new method gets better ringlet usage.The useful bandwidth is at least 25% more wider than the normal one.And it can be used in ringlets with different scales.
