云网一体使能网络即服务

[摘要] 随着云业务的深入部署，除接入和连接性服务外，云网运营商还须要将网络端到端带宽和时延等服务质量保障能力作为网络服务提供给最终客户。云网运营商基于云网一体网络架构，通过部署性能测量和故障发现、基于性能的路由、流量统计和状态预测，以及多域编排等系统，满足客户对不同需求层级能力的要求，使能网络即服务（NaaS）能力，实现网络与云化业务的有机结合。

[Abstract] In addition to access and connectivity services, cloud operators also provide multi-factor quality of service (QoS) assurance capabilities such as end-to-end bandwidth and delay as the network service to end customers. The cloud network service provider enables network as a service (NaaS) by building performance measure and fault detection, performance aware routing traffic statistics and state prediction, and multi-domain orchestration systems to match the hierarchy of service needs upon the cloud network architecture.
