【摘要】：全業(yè)務(wù)發(fā)展是當(dāng)今世界主流電信運營商的業(yè)務(wù)發(fā)展趨勢之一。全業(yè)務(wù)運營是運營商發(fā)展的重要突破點。 當(dāng)前全國各地LTE試驗網(wǎng)(Long Term Evolution,移動通信技術(shù)的長期演進)正在如火如荼建設(shè)中,2014年開始將是LTE網(wǎng)絡(luò)建設(shè)和發(fā)展的黃金期,各運營商將不遺余力地投入到LTE網(wǎng)絡(luò)的建設(shè)中,為4G(the4Generation mobile communication technology,第四代移動通信技術(shù))時代的通信市場競爭打下扎實的基礎(chǔ)。2011年開始的FTTH(Fiber To The Home,光纖到戶)建設(shè)更是將我國的寬帶速率提上了新的臺階。隨著互聯(lián)網(wǎng)業(yè)務(wù)需求爆炸式增長,無論是傳統(tǒng)的有線寬帶還是移動互聯(lián)網(wǎng),數(shù)據(jù)業(yè)務(wù)發(fā)展非常迅速,新建移動回傳網(wǎng)絡(luò)及大幅擴容的IP城域網(wǎng)的承載對現(xiàn)有光纜纖芯資源需求量猛增。 傳輸網(wǎng)絡(luò)是運營商重要的基礎(chǔ)網(wǎng)絡(luò)之一,建設(shè)規(guī)模和網(wǎng)絡(luò)質(zhì)量的好壞直接影響整個企業(yè)的業(yè)務(wù)發(fā)展。傳輸網(wǎng)作為基礎(chǔ)網(wǎng)絡(luò),不僅有大容量、高靈活性、高可靠性以及高質(zhì)量傳輸?shù)囊?還要有較好地支持IP業(yè)務(wù)傳輸?shù)囊�。因此在網(wǎng)絡(luò)發(fā)展的關(guān)鍵時期,MSTP(Multi-Service Transfer Platform,基于SDH的多業(yè)務(wù)傳送平臺)、OTN(OpticalTransportNetwork,光傳送網(wǎng))以及IPRAN網(wǎng)絡(luò)(IP化無線接入網(wǎng))如何部署也成為各大運營商的課題。 本文通過對主流城域傳輸技術(shù)SDH/MSTP、PTN(PTN Packet Transport Network,分組傳送網(wǎng))、IPRAN及DWDM(密集波分)、OTN等的比較,結(jié)合某運營商城域網(wǎng)現(xiàn)狀的調(diào)研、業(yè)務(wù)需求的預(yù)測及經(jīng)濟性評價,重點闡述了面向全業(yè)務(wù)運營背景下,如何根據(jù)當(dāng)前網(wǎng)絡(luò)現(xiàn)狀來制定適合本地區(qū)的傳輸網(wǎng)絡(luò)規(guī)劃。 本文總結(jié)了OTN網(wǎng)絡(luò)的建設(shè)思路及經(jīng)驗。本文從新技術(shù)選定、節(jié)點選定、系統(tǒng)速率選定等方面介紹了OTN網(wǎng)絡(luò)的建設(shè)思路。城域OTN網(wǎng)絡(luò)首先部署骨干層及匯聚層,在骨干層與匯聚層重合的節(jié)點,選用電交叉子架合一的方式部署,可實現(xiàn)骨干層對匯聚層業(yè)務(wù)的靈活調(diào)度,節(jié)約成本。網(wǎng)絡(luò)建設(shè)與IP網(wǎng)規(guī)劃緊密結(jié)合的同時,還需要考慮精確投資、投資管控。綜合考慮現(xiàn)有光纜、管道的資源狀況,對傳輸網(wǎng)資源進行合理利用,使投資效益最大化。結(jié)合目前的光纜纖芯資源及施工難度、建設(shè)工期等綜合因素,考慮目前市區(qū)及郊縣城區(qū)具備光纜資源或新建光纜條件的區(qū)域內(nèi),短距離10GE業(yè)務(wù)采用裸纖承載,較長距離10GE業(yè)務(wù)可采用OTN系統(tǒng)承載,對于GE業(yè)務(wù)則盡量采用OTN承載。隨著路由器100G端口的應(yīng)用推廣,城域OTN網(wǎng)絡(luò)業(yè)務(wù)面臨100G系統(tǒng)的建設(shè)。本文從技術(shù)、運維、成本等角度對40G/100G混傳網(wǎng)絡(luò)的可行性進行了分析。 本文總結(jié)了某運營商的IPRAN網(wǎng)絡(luò)建設(shè)經(jīng)驗。本文從綜合業(yè)務(wù)承載能力、可靠性與可擴展性、成本、網(wǎng)絡(luò)維護等角度分析了IPRAN的4種承載技術(shù),提出L2VPN(2層虛擬專用網(wǎng)絡(luò))+L3VPN(3層虛擬專用網(wǎng)絡(luò))在移動回傳網(wǎng)絡(luò)應(yīng)用。IP RAN網(wǎng)絡(luò)建設(shè)初期首先考慮與移動專業(yè)的需求緊密銜接,配合LTE建設(shè),加大IPRAN網(wǎng)絡(luò)建設(shè)范圍,確保LTE基站業(yè)務(wù)端到端質(zhì)量傳輸。明確網(wǎng)絡(luò)發(fā)展思路和方向,通過IP轉(zhuǎn)型架構(gòu)建設(shè)統(tǒng)一的綜合業(yè)務(wù)承載網(wǎng)。
[Abstract]:Full-service development is one of the business development trends of the mainstream telecom operators in the world.
At present, the LTE test network (Long Term Evolution, the long-term evolution of mobile communication technology) is being built in full swing. 2014 will be a golden period for the construction and development of LTE network. All operators will spare no effort to invest in the construction of LTE network, for 4G (the4Generation mobile communication technology, the fourth generation of mobile) Communication technology) the communication market competition in the era has laid a solid foundation for the FTTH (Fiber To The Home, fiber to the household) construction which has brought the broadband rate of our country to a new step. With the explosive growth of the Internet business demand, the development of data business is very rapid, whether it is the traditional cable broadband or the mobile Internet. The new mobile backhaul network and the large capacity expansion of the IP metropolitan area network have increased the demand for core resources of the existing fiber optic cable.
The transmission network is one of the important basic networks of the operators. The scale of construction and the quality of the network directly affect the business development of the whole enterprise. As a basic network, the transmission network not only has the requirements of large capacity, high flexibility, high reliability and high quality transmission, but also has a good support for the requirements of IP service transmission. The key period of the exhibition, MSTP (Multi-Service Transfer Platform, SDH based multi service transport platform), OTN (OpticalTransportNetwork, optical transmission network) and IPRAN network (IP wireless access network) how to deploy also become the major operators of the topic.
This paper compares the mainstream metropolitan area transmission technology SDH/MSTP, PTN (PTN Packet Transport Network, packet transmission network), IPRAN and DWDM (dense wave division), OTN and so on. It combines the current situation of a business city domain network, the prediction of business requirements and the economic evaluation. It focuses on how the current network is present under the background of the full business operation. Form a transmission network planning suitable for the local area.
This paper summarizes the idea and experience of the construction of OTN network. This paper introduces the construction ideas of OTN network from the aspects of the selection of new technology, the selection of nodes, the selection of system rate and so on. The city domain OTN network first deploys the backbone and aggregation layer, the joint of the backbone layer and the convergence layer, and selects the electric cross sub frame to be deployed in one way, and the backbone layer can be realized. At the same time, the network construction and the IP network planning are closely integrated, while the accurate investment and investment control are also needed to consider the existing optical cable, the resource status of the pipeline, the rational utilization of the transmission network resources, the maximum investment benefit, and the construction difficulty of the fiber core resources and construction. The short distance 10GE service is loaded with bare fiber, the long distance 10GE service can be loaded with OTN system and OTN bearer is adopted for the GE service. With the application and popularization of the 100G port of the routing device, the metropolitan area OTN network business face is also considered. This paper analyzes the feasibility of 40G/100G mixed transmission network from the point of view of technology, operation and maintenance, cost and so on.
This paper summarizes the IPRAN network construction experience of an operator. This paper analyzes 4 kinds of IPRAN bearing technology from the perspective of integrated service carrying capacity, reliability and scalability, cost and network maintenance, and puts forward L2VPN (2 layer virtual private network) (3 layer virtual private network) in the initial stage of the construction of.IP RAN network in the mobile return network. Considering the close connection with the demand of mobile specialty, with the construction of LTE, the scope of IPRAN network construction will be increased to ensure the end to end quality transmission of LTE base station business. The idea and direction of network development are clearly defined, and a unified integrated service bearing network is built through the IP transformation framework.
