【摘要】:本文以沈陽鐵通城域網(wǎng)的擴(kuò)容改造為背景,研究IP寬帶城域網(wǎng)的優(yōu)化改造與應(yīng)用問題。隨著廣大用戶對(duì)高品質(zhì)寬帶的日益需求以及上網(wǎng)用戶數(shù)的高速增長,沈陽鐵通原有的IP寬帶城域網(wǎng)已不能滿足寬帶業(yè)務(wù)的發(fā)展需求,需要在原有網(wǎng)絡(luò)框架的基礎(chǔ)上,改造成一個(gè)安全可靠、性能優(yōu)越、層次清晰,具有強(qiáng)大流量轉(zhuǎn)發(fā)能力、擴(kuò)展能力及可運(yùn)營的IP網(wǎng)絡(luò),能夠?yàn)閺V大用戶提供更多的寬帶業(yè)務(wù)應(yīng)用和高品質(zhì)的寬帶接入。 針對(duì)未來寬帶業(yè)務(wù)的發(fā)展需求,本文首先對(duì)對(duì)網(wǎng)絡(luò)流量優(yōu)化和物理結(jié)構(gòu)的改造進(jìn)行規(guī)劃和設(shè)計(jì)。通過對(duì)沈陽鐵通IP寬帶城域網(wǎng)的物理結(jié)構(gòu)改造進(jìn)行分析,規(guī)劃結(jié)構(gòu)框架,使網(wǎng)絡(luò)層次清晰化、網(wǎng)絡(luò)結(jié)構(gòu)扁平化。探討如何在整個(gè)寬帶城域網(wǎng)內(nèi)部署動(dòng)態(tài)路由協(xié)議,根據(jù)接入層、匯聚層、核心層的網(wǎng)絡(luò)需求和對(duì)OSPF、BGP等路由協(xié)議進(jìn)行分析比較,選擇最優(yōu)路由協(xié)議。對(duì)于互聯(lián)網(wǎng)高成本的網(wǎng)間結(jié)算,研究并制定出寬帶城域網(wǎng)流量、流向的優(yōu)化方案,并針對(duì)鐵通寬帶城域網(wǎng)的實(shí)際情況進(jìn)行部署和調(diào)整。 針對(duì)鐵通IP寬帶城域網(wǎng)的維護(hù),探討了其中需要解決的問題,對(duì)網(wǎng)絡(luò)的結(jié)構(gòu)以及日后寬帶業(yè)務(wù)的需求進(jìn)行了詳細(xì)的分析,提出了可靠的網(wǎng)絡(luò)結(jié)構(gòu)的設(shè)計(jì)方案。對(duì)網(wǎng)絡(luò)中的軟件、硬件的實(shí)現(xiàn)技術(shù)進(jìn)行了總結(jié)。對(duì)改造后的網(wǎng)絡(luò)進(jìn)行了較為全面的測(cè)試,結(jié)果表明該設(shè)計(jì)方案是滿足實(shí)際應(yīng)用需求的。
[Abstract]:This paper studies the optimization and application of IP broadband metropolitan area network based on the capacity expansion of Shenyang Tietong MAN . With the increasing demand of high - quality broadband and the high - speed growth of the number of users on the Internet , the existing IP broadband metropolitan area network in Shenyang can not meet the development requirement of broadband service .
In order to meet the development demands of broadband business in the future , this paper firstly plans and designs the improvement of network traffic optimization and physical structure . By analyzing and comparing the physical structure of Shenyang Tietong IP broadband metropolitan area network , this paper discusses how to deploy dynamic routing protocol in the whole wide band metropolitan area network . The optimal routing protocol is selected according to the network requirements of the access layer , aggregation layer , core layer and the routing protocols such as OSPF and BGP .
Aiming at the maintenance of IP broadband metropolitan area network , this paper discusses the problems to be solved , analyzes the structure of the network and the demand of broadband service in the future , and puts forward a reliable network structure design scheme . The software and hardware realization technology in the network is summarized . The results show that the design scheme is satisfied with the practical application requirements .
