摘要:
随着5G和光宽双千兆的发展，云网融合推动了 2B/2C/2H业务转型升级，传统 2B/2C/2H 客户需要网络提供大带宽、云化、敏捷、智能等高体验能力。现有的IP城域网络设备存在功能复杂、移动和固话分开进行承载、网络的灵活性差等问题，很难实现云网融合的业务一致性、自动化快速开通和智能化运营。因此通信运营商必须引进新的城域网技术，并重新构建城域网的基本构架，借助具备转控分离技术的vBRAS设备和FlexE/SRv6/EVPN等新一代信息技术的引入，以形成云化的、智能的、高度融合的体系。并围绕边缘云布局，构建低时延和高带宽等新型业务生态模式，以适应新的业务发展。
Abstract:
With the development of 5G and dual gigabit optical bandwidth, cloud network integration has driven the transformation and upgrading of 2B/2C/2H services. Traditional 2B/2C/2H customers need the network to provide high experience capabilities such as large bandwidth, cloudization, agility, and intelligence. The existing IP metropolitan area network equipment has problems such as complex functions, separate carrying of mobile and fixed phones, and poor network flexibility, making it difficult to achieve business consistency, automated rapid opening, and intelligent operation of cloud network integration. Therefore, communication operators must introduce new metropolitan area network technology and rebuild the basic architecture of the metropolitan area network, with the help of vBRAS devices with transfer control separation technology and the introduction of new generation information technologies such as FlexE/SRv6/EVPN, in order to form a cloud based, intelligent, and highly integrated system. And around the edge cloud layout, build new business ecological models such as low latency and high bandwidth to adapt to new business development.
