基于NFV的移动核心网可靠性研究
|
摘要
电信行业引入NFV,以运行在X86服务器上的网元功能软件化方式实现了软硬件解耦,以硬件资源池化的方式实现了资源共享共享,解决了电信网元烟囱式建设。在NFV架构下,由于硬件的可靠性下降,必然会导致网络可靠性下降。通过对NFV可靠性和可用性的分析,提出NFV架构下的检测机制和流程,同时给出快速故障恢复方案和容灾部署方案,为NFV场景下网络可靠性设计提供参考。
Introduced by the telecommunications industry, NFV is used to implement software and hardware decoupling in a software-based manner of network element functions running on X86 servers. Meanwhile, the resource sharing is realized by means of pooling hardware resources, and the chimney construction of the telecommunications network element thus solved. Under the NFV architecture, the reliability of the hardware is degraded, inevitably leading to a decrease of network reliability. Based on analysis of the reliability and availability of NFV, the detection mechanism and process under the NFV architecture are proposed, and the fast fault recovery scheme and disaster recovery deployment scheme also given, this could provide certain reference for network reliability design in the NFV scenario.
