Abstract

The invention provides a firewall based on a DPDK virtualization management system and an implementation method thereof. According to the invention, interruption is intercepted by using a DPDK pollingtechnology; according to the working principle that the UIO technology bypasses the kernel protocol stack and the message received by the network card is mapped to the user mode protocol stack f-stack through the UIO technology, the performance consumption during data packet capture is greatly reduced, and the data packet processing performance of the firewall is improved. A quick forwarding pathis added before a data packet enters an f-stack protocol stack; according to the method, session check is carried out on the data packet captured by the DPDK, and the flow of which the session is established is directly forwarded from the recorded port, so that the performance loss of the data packet in the process of passing through the protocol stack is reduced, the packet forwarding rate is improved, and the data processing performance of the firewall of the virtualization management system is further improved.

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...
