To improve the forwarding performance of NFV (Network Function Virtualization) in general server

this paper comes up with a hardware based VNF (Virtual Network Function) packet processing acceleration structure which is called FARD (Function Adaptive and Resource Dividable hardware structure).FARD can implement the hardware acceleration of any function instance on the L2/3/4 layer with programmable parser and action processor.And FARD also supports the dynamic resource allocation and function isolation between different instances with dynamic division on match table.The results based on the NetFPGA-10G platform show that the FARD acceleration structure increases by nearly 60 times in packets processing throughput compared with VNF which is only implemented by software.
