MicroNF:基于微服务的异构网络功能虚拟化框架

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.
