【摘要】：隨著通信技術(shù)在信息化建設(shè)領(lǐng)域的發(fā)展,傳輸網(wǎng)絡(luò)技術(shù)的發(fā)展也是日新月異。在激烈的市場競爭中，經(jīng)過十一年時間，亳州城域傳送網(wǎng)絡(luò)有了長足的發(fā)展，傳送網(wǎng)絡(luò)具有了一定規(guī)模，已形成核心層、匯聚層、接入層三個層面較清晰的分組化城域傳送網(wǎng)網(wǎng)絡(luò)結(jié)構(gòu)。為了滿足各業(yè)務(wù)網(wǎng)建設(shè)對傳輸通道的需求，提高傳送網(wǎng)的安全和運行質(zhì)量，考慮業(yè)務(wù)網(wǎng)IP化和分組化傳送網(wǎng)要求，進行組網(wǎng)研究，為以后業(yè)務(wù)的發(fā)展奠定基礎(chǔ)。 本論文就移動城域傳送網(wǎng)的特點，考慮雙節(jié)點組網(wǎng)，提出了優(yōu)化的策略，并結(jié)合移動城域傳送網(wǎng)的結(jié)構(gòu)，不僅對各個層面的優(yōu)化方法進行了論述，分析現(xiàn)有移動城域傳送網(wǎng)的現(xiàn)狀。通過現(xiàn)場勘查亳州核心層、匯聚層、接入層、互聯(lián)互通城域傳送網(wǎng)現(xiàn)狀，分析存在問題，進行城域傳送網(wǎng)傳輸帶寬需求預(yù)測。針對運營商自身的網(wǎng)絡(luò)資源情況、業(yè)務(wù)網(wǎng)絡(luò)的規(guī)模和結(jié)構(gòu)及未來的發(fā)展?jié)摿?提出了城域傳送網(wǎng)建設(shè)的基本思路、優(yōu)化原則及優(yōu)化方法，制定工程建設(shè)方案。實施完成后，對比傳送網(wǎng)帶寬改善情況，，評估城域傳送網(wǎng)的建設(shè)效果，并進一步解決傳送網(wǎng)帶寬不佳的地方，從而達到設(shè)計方案預(yù)期目標。 本論文的貢獻在于通過城域傳輸網(wǎng)的分析，結(jié)合市場需求和技術(shù)發(fā)展趨勢，提出了滿足市場發(fā)展需求并具有可出續(xù)發(fā)展性的城域傳輸網(wǎng)絡(luò)擴容傳輸方案。
[Abstract]:With the development of communication technology in the field of information construction, the development of transmission network technology is changing with each passing day. In the fierce market competition, after 11 years, Bozhou Metropolitan area transport network has made great progress, the transmission network has a certain scale, has formed the core layer, convergence layer, The three layers of access layer have clear packet transport network structure. In order to meet the demand of transmission channel and improve the security and operation quality of transport network, considering the requirements of IP and packet transport network, the research of network construction is carried out, which will lay a foundation for the development of service in the future. In this paper, considering the characteristics of mobile metropolitan transport network and considering the two-node network, the optimization strategy is put forward, and combining with the structure of mobile metropolitan transport network, not only the optimization methods of each level are discussed. The present situation of mobile metropolitan area transport network is analyzed. The present situation of metro transport network in Bozhou core layer, convergence layer, access layer and interconnection network is investigated. The existing problems are analyzed and the transmission bandwidth requirement of metropolitan transport network is predicted. In view of the network resources of the operators, the scale and structure of the service network and the development potential in the future, this paper puts forward the basic ideas, optimization principles and methods of metro transport network construction, and formulates the project construction plan. After implementation, the paper compares the improvement of transmission network bandwidth, evaluates the construction effect of metropolitan transport network, and further solves the problem of poor transmission network bandwidth, so as to achieve the expected goal of the design scheme. The contribution of this paper is that through the analysis of the metropolitan area transmission network, combined with the market demand and the trend of technological development, this paper puts forward a scheme of expanding the capacity of the metropolitan area transmission network, which can meet the market development demand and has the ability to develop continuously.
