无线接入网虚拟化发展探讨
|
摘要
引入SDN/NFV技术,重构基础网络设施,构建端到端云化网络是未来发展趋势。无线接入网络虚拟化研究目前相对滞后,因此立足协议虚拟化难度、虚拟化架构、性能保障等多个角度,探讨了无线接入网虚拟化存在的关键性问题,提出了基站虚拟化扩展架构,给出了保障基站可靠性、实时性和安全性的潜在解决方案。
To introduce SDN/NFV technology, to reconstruct network infrastructure and to build end-to-end cloud network are the future directions. The research on radio access network(RAN) virtualization is relatively lagging. Therefore, according to protocol virtualization difficulty, virtualized architecture and performance guarantee, the key problems in RAN virtualization are discussed. Finally, the base station virtualization architecture is proposed, while the potential solution to base station reliability, real time and security is presented.
