摘要/Abstract

摘要：

云网融合/云网一体已成为IP承载网的主要发展方向。作为最贴近用户的承载网，IP城域网拥有丰富的业务特性，是网络云化转型的重要试验田。面向多元接入、流量流向变化等网络承载需求，IP城域网从传统南北向树状架构向城域Spine-Leaf架构转型，以适应固移融合、多云接入等新型业务场景。基于云化IP城域网演进，对vBRAS池化部署方案及关键技术进行详细剖析，为vBRAS规模商用部署和技术演进提供技术参考。

关键词: 云化IP城域网, vBRAS, 池化

Abstract:

Cloud-network integration was the main development direction of IP carrier networks.As the closest network to users, IP MAN has rich service features and it is also an important test field for network cloudification.Facing the carrier requirements of multiple access and the changes of traffic direction, IP MAN was transformed from the traditional north-south tree architecture to the Spine-Leaf architecture to meet the service requirements, such as fixed-mobile convergence and multi-cloud access scenarios.Based on the evolution of the cloud IP MAN, the deployment scheme of pooled vBRAS and key technologies were introduced, and technical reference for the large-scale commercial deployment and technology evolution of vBRAS were provided.

Key words: cloud IP MAN, vBRAS, pooled
