摘　　要：针对局域网数据低延迟传输方法易受到信号碰撞影响,导致数据传输速率达不到理想状态的问题,提出了云计算环境中的局域网数据低延迟传输方法。分析局域网中的数据延迟和子流中数据块的分布特性,记录信息传输周期,避免信号同步碰撞。根据双冗余备份进行余量分配,分散传输低延迟数据,计算往返时间。在冗余调度结果的基础上,设计了以太网首尾结合的伪连接方式,实现局域网数据低延迟传输。由实验结果可知,该方法信号碰撞能量与理想数据一致,且通信速率与理想数据最大误差为500 bit/s,具有高效低延迟的传输效果。Aiming at the problem that the low delay transmission method of Local Area Network data is easily affected by signal collisions,resulting in the data transmission rate not reaching the ideal(LAN)state,a lowdelay transmission method of LAN data in a cloud computing environment is proposed.Analyze the data delay in the LAN and the distribution characteristics of the data blocks in the substream,record the information transmission cycle,and avoid signal synchronization collisions.According to the dual⁃redundant backup,the margin is allocated,the low delay data is dispersedly transmitted,and the roundtrip time is calculated.On the basis of redundant scheduling results,a pseudo⁃connection method combining Ethernet end to end is designed to realize low delay transmission of LAN data.It can be seen from the experimental results that the signal collision energy of this method is consistent with the ideal data,and the maximum error between the communication rate and the ideal data is 500 bit/s,which has high efficiency and low delay transmission effects.
