摘　　要：多元超立方体交换结构MHSF及相关汉明随机选路算法HRRA,是针对太比特路由器设计而提出的一种新的解决思路。时延性能是交换结构的重要性能指标。通过仿真在均匀流量条件下研究了时延性能与MHSF的链路加速因子s、元数k以及维数n的关系,找出了MHSF时延随着各个相关因素变化的规律。仿真结果表明,在较小参数条件下MHSF具有较好的时延性能。The new parallel distributed switching arch itecture-multi-ary hypercube switching fabric (MHSF) and a related routing alg orithm-hamming random routing algorithm (HRRA) was briefly introduced. The late n cy performance is one of the most important performances of a switching fabric. By simulating the latency performance of MHSF on condition of uniform traffic, t he relationship between MHSF's latency and related factors such as link accelera ting factor s, MHSF's ary k and dimension n was investigated, and the changing ru le of MHSF latency as changing of the related factors was given. The simulation results tell us MHSF has good latency performance with smaller parameters.
