【摘要】：為了分析移動(dòng)通信在未來幾年向5G演進(jìn)過程對(duì)傳輸尤其是PTN網(wǎng)絡(luò)的影響,基于無線網(wǎng)向5G發(fā)展將產(chǎn)生三種典型應(yīng)用以及技術(shù)發(fā)展的特征,探討了5G發(fā)展對(duì)傳輸網(wǎng)絡(luò)的關(guān)鍵需求:超高帶寬需求、低時(shí)延需求、網(wǎng)絡(luò)切片需求和東西向流量需求�；谝陨闲枨�,考慮未來面向5G的城域傳輸PTN網(wǎng)絡(luò)會(huì)逐步向三層下移,架構(gòu)向大容量、扁平化和靈活組網(wǎng)的方向發(fā)展,并且在實(shí)驗(yàn)室測(cè)試5G吞吐量的基礎(chǔ)上,通過建立模型對(duì)城域傳輸網(wǎng)內(nèi)帶寬進(jìn)行了測(cè)算,提出了城域傳輸網(wǎng)核心層、匯聚層、接入層的演進(jìn)方向和技術(shù)特征。
[Abstract]:In order to analyze the influence of mobile communication evolution to 5G in the next few years on transmission, especially on PTN network, the development of wireless network to 5G will produce three typical applications and the characteristics of technological development.This paper discusses the key requirements of 5G development for transmission network: ultra-high bandwidth demand, low delay demand, network slice demand and east-west traffic demand.Based on the above requirements, it is considered that the 5G oriented metro PTN network will gradually move down to three layers in the future, the architecture will develop towards the direction of large capacity, flat and flexible networking, and on the basis of testing 5G throughput in the laboratory,By establishing a model to calculate the bandwidth of the metropolitan transmission network, the evolution direction and technical characteristics of the core layer, convergence layer and access layer of the metropolitan transmission network are proposed.
