摘　　要：针对现有光传送网(OTN)专线承载网络存在的时延性能差、业务开通效率低以及网络智能化程度低等问题,文章提出了新一代政企专线承载网络组网策略,给出了100/200 Gbit/s、分组增强型OTN、OTN集群和可重构光分插复用器(ROADM)/光交叉连接(OXC)等传输新技术应用的建议,并将相关成果应用在某运营商政企专线承载网络商用部署中。结果表明,新一代政企专线承载网络具有显著的经济和社会效益,该运营商网络重点金融方向时延性能达到了业内领先,专线业务开通平均时长由以往60天缩短至15天,同时还具备业务端到端自动开通能力。Aiming at the problems of the existing Optical Transport Network(OTN)dedicated line bearer network,such as poor delay performance,low service opening efficiency,and low network intelligence,the paper proposes the networking strategy of the new generation government enterprise dedicated line bearer network.It gives the application suggestions of 100/200 Gbit/s,packet enhanced OTN,OTN cluster,Reconfigurable Optical Add-Drop Multiplexer(ROADM)/Optical Cross-Connect(OXC)and other new transmission technologies.The relevant results are also applied to the commercial deployment of an operator's government enterprise dedicated line bearer network.The results show that the construction of the new generation government enterprise special line bearer network has significant economic and social benefits.The delay of the operator's network in the key financial direction has reached the leading level in the industry.The opening time of the private line service has been shortened from the previous average of 60 days to 15 days.At the same time,the operator has the ability to automatically open the end-to-end service.
