基于VNF forwarding graph实现DNS分布式解析的一种方法

A method of DNS distributed parsing based on VNF forwarding graph

目前分布式DNS需借助BRAS专用硬件实现,与通用DNS服务器硬件不兼容,且其软件功能差异也较大,无法通用。针对上述问题,文章提出了基于VNF forwarding graph实现DNS分布式解析的一种方法,通过将DNS Agent和DNS cache虚拟化,实现了DNS的分布式部署,让DNS不再受限于硬件或软件兼容性的限制,让分布式DNS可以提供给各类场景(宽带、2G、3G)复用,即实现了DNS的分布式部署及统一复用。

At present,distributed DNS needs to be realized with special BRAS hardware,which is incompatible with the hardware of general DNS server,and its software function difference is not universal.In view of the above problems.In this paper,a method of DNS distributed parsing based on VNF forwarding graph is proposed.By virtualizing DNS Agent and DNS cache,the distributed deployment of DNS is realized,so that DNS is no longer restricted by hardware or software compatibility.Enabling distributed DNS to be reused for a wide variety of scenarios(broadband,2G and 3G),that is,real distributed deployment and unified reuse of DNS are presented.
