摘　　要：立足X省联通实际情况,对演进策略进行了研究。分析比较了智能城域网统一承载和现有承载方式的优缺点,提出了不同场景下的承载方案建议,并进行了现网试点应用,实现OLT上联TCO降低;利用SRv6+硬切片快速发布专线业务并充分保障质量;4G/5G业务统一承载退网冗余IPRAN设备。对如何根据网络实际情况,加速向智能城域网统一承载业务演进,大幅降低网络TCO、提升竞争力等有一定的借鉴意义。Based on the actual situation of China Unicom in X province,it studies the evolution strategy.It analyzes and compares the ad-vantages and disadvantages of the unified bearer and the existing bearer mode of the intelligent MAN,puts forward the bearer scheme suggestions under different scenarios,and carries out the pilot application in the existing network,so as to reduce the TCO of OLT uplink.It uses SRV6+hard chip to quickly release the special line service and fully guarantee the quality.4G/5G services are uniformly carried and redundant IPRAN devices are removed from the network.It has a certain reference signifi-cance on how to accelerate the evolution to the unified bearer service of intelligent MAN,greatly reduce the network TCO and enhance the competitiveness according to the actual situation of the network.
