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 論文介紹了波分復(fù)用系統(tǒng)的原理、發(fā)展歷程,討論了wdm全光網(wǎng)體系結(jié)構(gòu)、網(wǎng)絡(luò)物理拓?fù)浜瓦壿嬐負(fù)?,光交換/光路由等技術(shù)和關(guān)鍵器件,著重研究波長路由型全光網(wǎng)優(yōu)化設(shè)計中的路由和波長分配問題。
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 前者適合于業(yè)務(wù)矩陣變化不是太頻繁的網(wǎng)絡(luò),提出利用螞蟻算法解決業(yè)務(wù)的再路由問題,即利用螞蟻具有找到最短徑及不同種類螞蟻具有互斥的天然特性來進(jìn)行邏輯拓?fù)渲嘏渲?,從而保證了鏈路負(fù)載分布的平衡性。
