摘　　要：未来骨干传送网如何以更低的承载成本、更高可靠性和更低时延来满足业务需求,是运营商提高传送业务竞争力的根本手段。通过定位影响传输承载成本和电路时延的关键因素,分析现有中国联通骨干传送网络架构对降低承载成本和时延的不利条件,提出了基于ROADM技术进行一二干统筹组网的扁平化思路,旨在有效降低骨干传送网的承载成本和业务时延,并给出了包括网络组织、设备技术选择和运维等方面的建设方案及意见建议。How the future backbone transport network can satisfy the service demand with lower carrying cost, higher reliability and low- er delay, is the basic means for operators to improve the competitive ability of the transmission service. Through positioning the key factors which influence the transmission carrying cost and the time delay,analyzing the existing China Unicorn back- bone transport network architecture, it proposed the flat networking idea of the backbone transport network based on ROADM technology,aiming to reduce the carrying cost and the transmission delay.The construction scheme and suggestions about network organization, equipment ＆ technology selection, operation and maintenance are given.
