摘要
网络功能虚拟化(NFV)带来灵活性的同时也面临极大的问题,因为承载网络功能的虚拟机可能会引入显著的性能开销。针对此问题,提出了一种名为MicroNF的新型高性能可编程框架,将可编程硬件基础设施与NFV中的传统软件基础设施相结合,以实现高性能和灵活性。MicroNF利用微服务——一种软件架构中的新设计方法,重新构建NFV,以实现服务之间的功能可重用性并提高性能。基于OpenStack和ONetCard的实验平台实现了MicroNF。实验结果表明,与基于DPDK的软件实现相比,MicroNF将服务链的平均转发时延降低了70%。
Network function virtualization(NFV)brought significant flexibility.However,such flexibility came with considerable compromises,since virtual machine carried monolithic functions could introduce significant performance overhead.A novel high-performance and programmable framework called MicroNF was proposed,which combines programmable hardware infrastructure and traditional software infrastructure in NFV to achieve both high performance and flexibility.In particular,microservice,a new design approach in software architecture,was leveraged by MicroNF to re-architect NFV to enable functional reusability among services and improve performance.MicroNF was implemented in a test bed based on OpenStack and ONetCard.Experimental results show that MicroNF reduces the forwarding latency of a service chain by an average of 70%compared with DPDK-based software implementation.
