一个分层的互连网络，TESH（托里连接mESHes）允许利用计算的局部性以及模块化的未来扩展。为了在TESH上实现虫孔路由，需要在基本模块上分配适当的虚拟通道，因为虚拟通道的数量取决于BM间链路的分配策略。提出了一种使网络直径和虚通道数最小的链路分配策略。对TESH和mesh网络的动态通信性能进行了仿真。可以看出，TESH的动态通信性能优于网状互连。
A hierarchical interconnection network, TESH (Tori connected mESHes) allows exploitation of computational locality as well as modular future expansion. To implement a worm-hole routing on TESH, an appropriate method is required to allocate virtual channels on a basic module, since the number of virtual channels depends on allocation policy of inter-BM links. The paper addresses a link allocation policy that minimizes the network diameter and the number of virtual channels. Dynamic communication performances are simulated for TESH and mesh networks. It is seen that the dynamic communication performance of TESH is better than mesh interconnection.
