【摘要】:傳統(tǒng)的移動(dòng)承載網(wǎng)網(wǎng)絡(luò)是基于TDM/SDH建成的,對(duì)于顆粒度較小、帶寬需求不大的業(yè)務(wù)如2G基站,TDM/SDH都能滿(mǎn)足網(wǎng)絡(luò)發(fā)展的需求,但是隨著3G和LTE等系統(tǒng)的部署與發(fā)展,數(shù)據(jù)業(yè)務(wù)已成為承載主體,其對(duì)帶寬的需求在迅猛增長(zhǎng)。SDH傳統(tǒng)的TDM獨(dú)享管道的網(wǎng)絡(luò)擴(kuò)容模式難以支撐,分組化的承載網(wǎng)建設(shè)已經(jīng)成為一種不可逆轉(zhuǎn)的趨勢(shì)。在此背景下,中國(guó)電信集團(tuán)選擇了IP RAN技術(shù)建設(shè)移動(dòng)承載網(wǎng)絡(luò)。本文首先介紹了移動(dòng)承載網(wǎng)絡(luò)面臨的形勢(shì)及未來(lái)發(fā)展趨勢(shì),分析了IP RAN技術(shù)的優(yōu)勢(shì)和特點(diǎn)。對(duì)寧夏電信省內(nèi)IP RAN網(wǎng)絡(luò)現(xiàn)狀進(jìn)行了分析,對(duì)基站承載需求、業(yè)務(wù)傳輸帶寬需求進(jìn)行了預(yù)測(cè)。本文重點(diǎn)對(duì)寧夏電信省內(nèi)IP RAN網(wǎng)絡(luò)建設(shè)方法進(jìn)行了設(shè)計(jì),結(jié)合IP RAN網(wǎng)絡(luò)的特點(diǎn),給出了寧夏電信基于IP RAN技術(shù)的移動(dòng)承載網(wǎng)方案,包括3層(核心層、匯聚層和接入層)的組網(wǎng)結(jié)構(gòu)、節(jié)點(diǎn)的設(shè)置、A類(lèi)與B類(lèi)設(shè)備的互連方式、三層路由的設(shè)置、IP地址配置和VPN部署策略等。最后對(duì)IP RAN的綜合業(yè)務(wù)承載進(jìn)行了分析,對(duì)后期政企業(yè)務(wù)割接至IP RAN網(wǎng)絡(luò)承載進(jìn)行了設(shè)計(jì)。
[Abstract]:The traditional mobile bearer network is built based on TDM/SDH. For services with small granularity and low bandwidth requirement, such as 2G base station, TDM/SDH can meet the needs of network development. However, with the deployment and development of 3G and LTE systems, Data service has become the main carrier, and its demand for bandwidth is growing rapidly. The traditional TDM network expansion mode of SDH is difficult to support, and the construction of packetized bearer network has become an irreversible trend. In this context, China Telecom Group chose IP RAN technology to build mobile bearer network. This paper first introduces the situation and future development trend of mobile bearer network, and analyzes the advantages and characteristics of IP RAN technology. The present situation of IP RAN network in Ningxia telecom province is analyzed, and the demand of base station carrying capacity and service transmission bandwidth is forecasted. This paper focuses on the design of the construction method of IP RAN network in Ningxia Telecom province. According to the characteristics of IP RAN network, this paper gives the mobile carrying network scheme of Ningxia Telecom based on IP RAN technology, which includes three layers (core layer, core layer). The network structure of convergence layer and access layer, the setting of nodes, the interconnection mode between class A and class B devices, the setting of three-layer routing, the configuration of IP address and the policy of VPN deployment, etc. Finally, the comprehensive service carrying capacity of IP RAN is analyzed, and the design of the later government business cutting to IP RAN network carrying capacity is carried out.
