摘要
网络流量的大幅增长和用户带宽需求的不断提升对有线电视接入网的灵活性、可扩展性提出新的要求。软件定义网络(SDN)和网络功能虚拟化(NFV)技术为有线电视接入网提供了新的思路。在综合考虑业务发展和运营商实际需求的基础上,提出了软件定义的有线电视接入网架构,重点研究了面向异构接入设备的虚实结合管理技术和面向多客户多业务的接入网资源切片技术,并总结了未来的研究方向。
The rapid increase of network traffic and users’ bandwidth requirement put forward new requirements for the flexibility and scalability of cable access networks. The emerging of software defined networking(SDN) and Network Function Virtualization provides a promising way to solve this problem. The software-defined cable access network architecture is proposed based on the consideration of service development and the needs of operators. The management technology of virtual and physical access devices and the resource slicing technology for multi-client and diverse services are introduced, and the future research directions are concluded in this field.
