4紧优和5紧优双环网络无限族

Infinite Families of 4-Tight and 5-Tight Optimal Double-loop Networks

双环网络是计算机互连网络或通讯系统的一类重要拓扑结构。本文推广了文献[6]的主要结论,给出一个较一般的紧优双环网络无限族构造方法,从而得到若干类4紧优和5紧优双环网络无限族。

Double-loop network （DLN） is an important class of topological structure of the lnternet or communication system. In this paper, the main result of Reference [6] is generalized and a constructing method for an infinite family of a general tight optimal double-loop network is presented. As a result, some infinite families of 4- tight and 5-tight optimal double-loop networks are gained.
