摘要
接入网作为用户接入网络的第一道门户,是用户体验的核心,是联系业务与用户的纽带。随着互联网服务驱动网络架构的变革,人们对接入网提出了新的要求,需要接入网具备智能、开放化等特点,而传统的接入网架构与技术难以满足需求。SDN/NFV技术为接入网提供了全新的思路,如控制与转发分离、集中控制等,使网络服务与具体的硬件分开,为接入网的设计、部署和管理带来了很大的灵活性。本文结合有线电视宽带接入网技术现状,探讨了SDN/NFV技术在有线电视宽带接入网中的应用。
As the first gateway to access the network,accessing network is crucial to user experience.Driven by the Internet service,people put forward new requirements for accessing network,such as intelligence and openness.The traditional accessing network is difficult to meet those requirements.SDN/NFV technology provides new ideas for accessing network,such as a separation of control and distribution,centralized control,etc.,which make network services separate from specific hardware and bring great flexibility to the design,deployment and management of accessing network.This paper discusses the application of SDN/NFV technology in CATV broadband accessing network.
