【摘要】：隨著互聯(lián)網(wǎng)的快速發(fā)展,收發(fā)郵件和瀏覽網(wǎng)頁已不是人們上網(wǎng)的唯一目的,而是希望以最小的花費(fèi)獲取更多的寬帶服務(wù),虛擬專用網(wǎng)(VPN)、局域網(wǎng)高速互聯(lián)、實(shí)時(shí)影視點(diǎn)播(VOD)、遠(yuǎn)程教育、遠(yuǎn)程醫(yī)療等各種業(yè)務(wù)方興未艾,應(yīng)用要求寬帶城域網(wǎng)可以滿足多業(yè)務(wù)同時(shí)開展,對(duì)城域網(wǎng)底層的傳輸和交換融合提出了極高的期望。城域網(wǎng)多業(yè)務(wù)環(huán)(Multiple Services Ring, MSR)是武漢郵電科學(xué)研究院提出的,具有國(guó)際先進(jìn)水平的的光城域網(wǎng)組網(wǎng)和應(yīng)用國(guó)際標(biāo)準(zhǔn),可以實(shí)現(xiàn)傳輸與交換的一體化,從而促進(jìn)多業(yè)務(wù)的融合,MSR創(chuàng)造性的提出了支路業(yè)務(wù)這一概念,可以實(shí)現(xiàn)業(yè)務(wù)傳輸與交換的完美結(jié)合,被ITU-T采納。而支路業(yè)務(wù)的關(guān)鍵技術(shù)是支路業(yè)務(wù)保護(hù),只有實(shí)現(xiàn)了支路業(yè)務(wù)的保護(hù),支路業(yè)務(wù)才能正常傳輸和交換。本文首先對(duì)MSR標(biāo)準(zhǔn)進(jìn)行了全面研究分析,并提出了實(shí)現(xiàn)方案。研究?jī)?nèi)容主要包括業(yè)務(wù)模式、支路保護(hù)、性能檢測(cè)幾個(gè)方面。詳細(xì)論述了兩種模式、兩種管理、兩種監(jiān)測(cè),即在環(huán)上運(yùn)行的業(yè)務(wù)可提供單播、組播和廣播模式,支路業(yè)務(wù)的1+1,1：1,1：N保護(hù)模式,支路帶寬管理和優(yōu)先級(jí)管理,支路性能監(jiān)測(cè)和安全過濾監(jiān)測(cè)。本文創(chuàng)新性地提出一種基于支路的故障檢測(cè)和倒換協(xié)商機(jī)制,這個(gè)機(jī)制充分利用了MSR分組化的優(yōu)勢(shì),提高了MSR支路保護(hù)的公平性和穩(wěn)定性。設(shè)計(jì)了基于MSR網(wǎng)絡(luò)中鏈路倒換時(shí)間的實(shí)現(xiàn)及仿真,并在不同網(wǎng)絡(luò)結(jié)構(gòu)下對(duì)MSR over RPR的倒換時(shí)間與其他幾種以太環(huán)網(wǎng)保護(hù)時(shí)間進(jìn)行比較,證明了MSR在業(yè)務(wù)保護(hù)上的優(yōu)勢(shì)。論文還在標(biāo)準(zhǔn)的基礎(chǔ)上對(duì)城域網(wǎng)多業(yè)務(wù)環(huán)網(wǎng)絡(luò)模型和系統(tǒng)進(jìn)行設(shè)計(jì),論文工作為MSR技術(shù)的發(fā)展及普及奠定了良好的基礎(chǔ),具有較大的理論意義和實(shí)用價(jià)值。
[Abstract]:With the rapid development of the Internet, sending and receiving mail and browsing web pages are not the only purpose of people to surf the Internet, but they hope to get more broadband services at the minimum cost, virtual private network (VPN) and LAN (Local area Network) are connected at high speed. Real time video-on-demand (VOD), distance education, telemedicine and other services are in the ascendant. Applications require broadband metropolitan area networks to meet the requirements of multi-service simultaneous development. A high expectation is put forward for the transmission and exchange fusion of the bottom layer of the man. MSRs are the international standards for organizing and applying the optical metropolitan area network (man) with international advanced level, which is proposed by Wuhan Research Institute of Post and Telecommunications Sciences. It can realize the integration of transmission and exchange, thus promote the integration of multi-service. MSR creatively puts forward the concept of branch service, which can realize the perfect combination of service transmission and exchange. Adopted by ITU-T. The key technology of branch service is branch service protection. Only when branch service protection is realized, can branch service be transmitted and exchanged normally. Firstly, this paper makes a comprehensive study and analysis of MSR standard. The research contents mainly include business mode, branch protection and performance testing. Two modes, two kinds of management and two kinds of monitoring are discussed in detail, that is, the business running on the ring can provide unicast. Multicast and broadcast mode, 11 / 1: 1: 1: n protection mode of branch service, branch bandwidth management and priority management, branch performance monitoring and security filtering monitoring. This mechanism makes full use of the advantage of MSR grouping, improves the fairness and stability of MSR branch protection, and designs the implementation and simulation of link switching time based on MSR network. The switching time of MSR over RPR is compared with that of other Ethernet ring networks under different network structure. This paper proves the advantage of MSR in service protection. This paper also designs the model and system of man multi-service ring network on the basis of standard. The work of this paper lays a good foundation for the development and popularization of MSR technology. It has great theoretical significance and practical value.
