摘　　要：由于数据传输节点能量有限,易受到节点负载不均衡影响,无法选择有效的传输通道,因此节点存活率较低、时延较高。为此,提出了考虑节点负载的光纤通道多路数据混合传输方法。采用关键能量平均值计算方法,计算所有路由路径关键能量值,根据光纤通道整体能耗选择传输路径。通过可变边界的时间轴多路复用帧结构,建立初始传送路径,采用能量平衡法为多路径分配传输工作量,估算各路径所承载的数据传输量。充分考虑节点负载,计算从源节点到目标节点的路由能量消耗,避免了节点过量负载。采用时分复用与波分复用混合方式,实现光纤通道多路数据混合传输。实验结果表明,该方法最高时延达到0.5 s,节点存活率为0.96,能够有效实现光纤通道多路数据高质量混合传输。Due to the limited energy of data transmission nodes,they are vulnerable to the impact of node load imbalance,and cannot choose an effective transmission channel,resulting in low node survival rate and high delay.For this reason,a hybrid data transmission method based on fibre channel and node load is proposed.The critical energy average calculation method is used to calculate the critical energy value of all routing paths,and the transmission path is selected according to the overall energy consumption of fibre channel.The initial transmission path is established through the time axis multiplexed frame structure with variable boundary.The energy balance method is used to allocate the transmission workload for multiple paths,and the data transmission capacity carried by each path is estimated.The node load is fully considered,and the routing energy consumption from the source node to the target node is calculated to avoid excessive node load.The hybrid mode of time division multiplexing and wavelength division multiplexing is adopted to realize the hybrid transmission of multi-channel data in fibre channel.The experimental results show that the maximum time delay of this method is up to 0.5 s,and the node survival rate is 0.96,it can effectively realize the high-quality mixed transmission of multi-channel data in fibre channel.
