The loop free logical topology created is called a tree 没有?圈的逻辑拓扑叫做树。
This topology is a star or extended star logical topology 这种拓扑是星状或延伸式星状的逻辑拓扑。
The algorithm used to create this loop free logical topology is the spanning-tree algorithm 用来建立没有?圈的逻辑拓扑之演算法通常称为扩充树演算法。
A new algorithm called the rapid spanning-tree algorithm was developed to reduce the time for a network to compute a loop free logical topology 一个新的演算法叫做快速扩充树演算法,是开发用来减少网路上,计算一个没有?圈的逻辑拓扑所需的时间。
First, the growing history and the basic principle of the wdm optical networks are introduced, then the construct of the wdm all-optical networks is discussed, physical topology and logical topology and so on . then, the routing technology in wdm system is presented in this paper, as well as key optical components in optical networks . the routing and wavelength assignment issue in the optimal design of rwa algorithm is particularly explored 论文介绍了波分复用系统的原理、发展历程,讨论了wdm全光网体系结构、网络物理拓扑和逻辑拓扑,光交换/光路由等技术和关键器件,着重研究波长路由型全光网优化设计中的路由和波长分配问题。
For optical-layering approach, we propose an ant-based algorithm, which uses the ants " capability of finding shortest or near-shortest paths between a food source and their nests, to solve the logical topology reconfiguration problem . we give the ants routing formula based on dynamic load balancing and short path on the assumption that some conditions hold 前者适合于业务矩阵变化不是太频繁的网络,提出利用蚂蚁算法解决业务的再路由问题,即利用蚂蚁具有找到最短径及不同种类蚂蚁具有互斥的天然特性来进行逻辑拓扑重配置,从而保证了链路负载分布的平衡性。
