There are two control models of network interconnection for the astn , one the overlay model and the other the peer model Astn的網(wǎng)絡(luò)互聯(lián)控制模型主要有兩種,一種是重疊模型( overlaymodel ) ,另一種是對(duì)等模型( peermodel ) 。
In the overlay model , the addressing scheme , the routing protocol and the signaling protocol at the customer layer run independently from those at the transfer layer 在重疊模型中,客戶層的地址方案、路由協(xié)議和信令協(xié)議與傳送層的地址方案、路由協(xié)議和信令協(xié)議各自獨(dú)立運(yùn)行。
Based on the above analysis , taking into account the present situation of the telecommunications operators and the characteristics of the traffic , it is desirable to adopt the overlay model in the near term . when ip - based service becomes the mainstream , the peer model will be the direction 基于以上分析,從電信運(yùn)營商的現(xiàn)實(shí)情況及業(yè)務(wù)特點(diǎn)出發(fā),近期發(fā)展方向應(yīng)是采用重疊模型。未來基于ip的業(yè)務(wù)成為主導(dǎo)業(yè)務(wù)時(shí),對(duì)等模型將是目標(biāo)。
The evolution history and trend for ason are analysised in this paper . then it concluded that ason is inevitably to take place of traditional optic network for its explicit defect in meeting requirement of modern service . then it explain the two typical hierarchy and function architecture network models , named overlay model and peer model 論文分析了光網(wǎng)絡(luò)的發(fā)展歷史及趨勢,指出了傳統(tǒng)光網(wǎng)絡(luò)的不足及引入自動(dòng)交換光網(wǎng)絡(luò)的必要性,從層次結(jié)構(gòu)和功能結(jié)構(gòu)兩個(gè)方面分析了ason的網(wǎng)絡(luò)體系結(jié)構(gòu)及重疊和對(duì)等兩種網(wǎng)絡(luò)模型,論文還分析了通用多協(xié)議標(biāo)簽交換( gmpls )協(xié)議族及其在ason控制平面中的應(yīng)用。
