Under the development trend of high throughput, large capacity and strong time effective data security transmission of the second generation data relay system in China, the high-performance processing requirements for the firewall of the backbone network security protection equipment are constantly improving. Focusing on the characteristics of the second generation data relay system, the key technologies of the transmission processing of the 10 Gigabit firewall based on the x86 architecture for different data flows are researched, the optimization design of the CPU allocation and scheduling mode, the function judgment mechanism of the network card characteristics and the kernel state write operation function of the 10 Gigabit firewall are completed. The test results show that the optimized 10 Gigabit firewall gives full play to its maximum transmission performance, and provides a better security transmission service guarantee for the integrated data relay users.
Key words: Ten Gigabit firewall / High speed data transmission / Kernel scheduling / Network card characteristics
