Abstract

The present invention provides a firewall based on the DPDK virtualization management system and its implementation method. The present invention utilizes the polling technology of DPDK to intercept interrupts, solves the loss problem caused by interrupt processing, and utilizes UIO technology to bypass the kernel protocol stack, through UIO technology maps the packets received by the network card to the working principle of f-stack, the user mode protocol stack, which greatly reduces the performance consumption when capturing data packets, and improves the performance of the firewall in processing data packets. A fast forwarding path is added before the data packet enters the f-stack protocol stack, and the session check is performed on the data packet captured by DPDK. The performance loss caused by the process of the protocol stack increases the packet forwarding rate, thereby improving the data processing performance of the firewall of the virtualization management system.

Description

technical field [0001] The invention relates to the technical field of firewalls, in particular to a firewall based on a DPDK virtualization management system and an implementation method thereof. Background technique [0002] With the development of optical fiber technology, the network bandwidth is rapidly increasing and the system business volume is increasing. The software technology performance is based on the traditional network protocol stack. The firewall has a complex process for data packet processing and high overhead, which cannot meet people's needs for high-performance processing of dense data. Requirements, so the research and development of high-performance firewall is of great significance. Contents of the invention [0003] The purpose of the present invention is to provide a firewall based on the DPDK virtualization management system and its implementation method, aiming to solve the problems of complex processing flow and high performance overhead of th...
