Research on the Improvement of Linux Network Performance in Multi-Core Environment

With the rapid development of Internet, regardless of the enterprise itself or customers increasingly rely on the Internet to deal with important business. In recent years, hacker attacks continue to occur, information security becomes an important issue, and intrusion detection system is one of the major development projects. There are many products intrusion detection systems now, but their prices are quite expensive, which for most schools and small companies is the huge cost. Because the PC and Linux with a low-cost high-performance characteristics, so that they become the important hardware and software trends. In recent years, PC's development from a single processor to multi-core processors, which has become the operating system and application development challenges.Linux is a flexible, supportive, network-performance operating system, so widely used in network systems. But Linux support in the multi-core processors is still not good, so Linux multi-core processors in the network performance is low. The purpose of this project is to improve the Linux network performance in the multi-core processors. We modify the Linux multi-core processors network interrupt handler function, which aims to enhance the Linux intrusion prevention system.
