摘要
傳輸網(wǎng)作為各種業(yè)務(wù)網(wǎng)和業(yè)務(wù)的傳送載體,是整個電信運(yùn)營網(wǎng)絡(luò)的基礎(chǔ)。本文主要分析和討論了本地同步數(shù)字體系(SDH)傳輸網(wǎng)絡(luò)的現(xiàn)狀,對分層式網(wǎng)絡(luò)結(jié)構(gòu)、環(huán)網(wǎng)絡(luò)結(jié)構(gòu)、設(shè)備配置中再生段的計(jì)算和網(wǎng)絡(luò)同步問題,及其應(yīng)用條件作了較為詳盡的描述,并從實(shí)用的角度出發(fā)以XX市本地傳輸網(wǎng)為例介紹了如何對SDH網(wǎng)絡(luò)進(jìn)行規(guī)劃和分析,并且對本地SDH傳輸網(wǎng)絡(luò)的發(fā)展和規(guī)劃作了深入淺出的論述,強(qiáng)調(diào)了傳輸網(wǎng)絡(luò)規(guī)劃在通信網(wǎng)建設(shè)中的重要性[1]。 論文介紹了XX市傳輸網(wǎng)的現(xiàn)狀,并提出了網(wǎng)絡(luò)規(guī)劃的具體步驟。首先提出傳輸網(wǎng)規(guī)劃建設(shè)的總體指導(dǎo)原則,在此基礎(chǔ)上提出構(gòu)建傳輸網(wǎng)的三個基本網(wǎng)絡(luò)(管道網(wǎng)、光纜網(wǎng)和設(shè)備網(wǎng));其次在遵循上述原則的基礎(chǔ)上,結(jié)合XX市的具體情況,給出該市傳輸網(wǎng)絡(luò)規(guī)劃的詳細(xì)方法和過程,在規(guī)劃方案中明確了關(guān)于傳輸匯聚點(diǎn)和匯聚層的關(guān)鍵作用;根據(jù)實(shí)際業(yè)務(wù)需求以及面向3G網(wǎng)業(yè)務(wù)的需要,明確了基于SDH的MSTP技術(shù)解決方式;最后,通過分析得出XX市傳輸網(wǎng)發(fā)展仍應(yīng)采用基于SDH的MSTP技術(shù),并且在ASON技術(shù)成熟后可以在核心骨干層采用MSTP OVER ASON或WDM OVER ASON,而在匯聚接入層仍以MSTP為主的結(jié)論。
Transmission Network is the foundation of the whole Telecom Operation Netwok,as a transmission vector of Business Network and business. This paper anlyses and dicusses the status quo of local SDH Transmission Network, made a detailed description of the Hierarchical Network structure, Ring Network architecture, the computing problem of device configuration renewable paragraph , network synchronization and application conditions, at the same time, from a practical point of view to the local Transmission Network in XX City as an example to introduce how to SDH Network planning and analysis, and local SDH Transmission Network development and planning were discussed in simple terms, stressed the importance of Transmission Network planning in Communication Networks construction .
The paper dicussed the status quo of Transmission Network in XX city , and proposed concrete steps to network planning. First of all, proposed the overall guiding principles of the planning and construction of Transmission Network, in this based proposed methods of network planning and design and planning principles of three basic networks for the building Transmission Network ( Pipeline Networks, Cable Networks and Equipment Networks);the second, on the basis of the above-mentioned principles in combination with the specific circumstances of the city XX city, given the city a detailed planning methods and process in Transmission Network, in planning program cleared on the key role of aggregation point and the transmission convergence layerthe transmission; in accordance with the actual business needs, as well as business-oriented needs of 3G networks, cleared the solutions of the SDH-based MSTP technology; Finally, analysis of the development of XX city Transmission Network should be based on SDH technology of MSTP, and can be used in the core backbone layer MSTP OVER ASON or WDM OVER ASON when ASON technology is mature, and converged access layer is still the main conclusions of MSTP.
