Software-defined protocol independent parser based on FPGA

Abstract

With the boom of information technology, heterogeneous networks with various functions emerge in endlessly, heterogeneous fusion network has become the inevitable trend of the development of the next generation network. To realize communication between heterogeneous networks, network forwarding equipment is essential. Traditional forwarding devices only support fixed protocol configuration and lack scalability, so they cannot support new network protocols. In view of this situation, a software defined protocol independent parser based on FPGA was proposed. The software defined the parsing process, giving the parser flexible and programmable features. It can analyze multiple protocol packets and extract key information needed for protocol conversion without changing hardware devices. The parser through a high-performance FPGA platform were implemented and hardware resource overhead and performance were evaluated. Experimental results show that it can complete the fast parsing of various heterogeneous network protocols and obtain complete analytical data.
