摘　　要：对互连网络中Torus拓扑结构的链路利用率低和负载不匀衡问题,本文提出了一种新的分级互连网络结构——RTTM网络拓扑结构。该拓扑结构分为N级,第1级由2m×2m个节点的Mesh拓扑结构构成,第2级到第N级由a×2a个节点的长方形扭Torus拓扑结构以递归方式连接而成。本文在OPNET的建模环境下分别完成了RTTM网络拓扑结构的两级建模,第一级由4×4个节点的Mesh拓扑结构构成,第二级由4×8个节点的扭Torus拓扑结构构成。仿真结果表明RTTM网络拓扑结构链路利用率高,端到端延迟小,吞吐量大。For the low utilization rate and uneven load value on the Rectangular Torus,this paper presents a new hierarchical twist Torus structure——RTTM.It is a N-level network.The Level-1 sub-network,also called a Basic Module,consists of a mesh connection of 2^m×2^m nodes.Successively higher level networks are built by recursively interconnecting a×2a nodes in the form of a Rectangular Twisted Torus.With the OPNET modeling environment,this paper completed seperately two levels modeling of the RTTM network structure.The first level is made up of 4×4 nodes of Mesh structure,and the second level is made up of 4×8 nodes of Torus structure.The simulation results show that the network has high utilization rate,smaller end-to-end delay and larger throughput by OPNET.
