OTN技术在辽宁交通通信骨干网设计中的应用

摘要

With the enhancement and promotion of soft exchange technology, high definition monitoring technology and information system based on IP, Liaoning transportation data service has showed a growth spurt, and the existing transmission network based on SDH has not met the requirement of Liaoning transportation information development.Based on the current situation of Liaoning transportation communication transmission network, OTN technology is adopted in the design of Liaoning transportation communication backbone network to gradually replace the existing SDH backbone transmission network, so as to improve the bandwidth and safety of network, meet the requirement of Liaoning intelligent transportation management and guarantee the high efficient and reliable operation of bearer service.%随着基于IP的软交换技术、高清监控技术和信息系统的深化推广,辽宁交通的数据业务已呈现出井喷式增长,现有基于SDH的传输网已不能满足辽宁交通信息化发展的需求.基于辽宁交通通信传输网络的现状,在辽宁交通信息通信骨干网设计中采用OTN技术,逐步替换现有的SDH骨干传输网,以提高网络的带宽和安全性,满足辽宁智慧交通管理需求,保证承载业务高效、可靠的运行.
