基于智能网络的租户服务质量保证技术

在多租户虚拟网络环境中,用户对于网络服务的多样性以及性能的稳定性需求并不会随着网络架构和运营模式的升级而削弱,用户需求之间的差异性和动态性对于不同切片间资源的分配和调度效率提出了新的挑战。针对多租户虚拟网络的特殊环境,首先提出了QVR(QoS-Virtual Routing)流量调度算法,同时将用户流量调度与网络虚拟资源分配看做一个联合优化问题,提出了面向多租户的流量调度算法以及适用于共享链路的动态带宽分配算法。该算法能够释放更多的物理网络资源,明显降低了租户网络的延时和拥塞。

Tenant Service Quality Assurance Technology Based on Intelligent Network

In a multi-tenant virtual network environment,users'requirements for the diversity of network services and the stability of performance will not be compromised by the upgrading of network architecture and operating mode.The differences and dynamics between user needs pose new challenges for resource allocation and scheduling efficiency among different slices.Aiming at the special environment of multi-tenant virtual networks,the QVR(QoS-Virtual Routing)traffic scheduling algorithm is first proposed.User traffic scheduling and network virtual resource allocation are regarded as a joint optimization problem.And a multi-tenant-oriented traffic scheduling algorithm and a dynamic bandwidth allocation algorithm suitable for shared links are proposed.This approach can release more physical network resources,significantly reducing the delay and congestion of tenant networks.
