Introduction

Linux is a free-to-use and freely disseminated Unix-like operating system kernel. It is a multi-user, multi-task, multi-thread and multi-CPU based on POSIX and Unix operating system kernel. With the development of the Internet, Linux has received support from software enthusiasts, organizations, and companies all over the world. In addition to maintaining a strong development momentum in servers, it has made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs, so that it can best meet the needs of users.

Linux is not only stable in system performance, but also open source software. Its core firewall components are highly efficient and easy to configure, which ensures the security of the system. In many enterprise networks, in order to pursue speed and security, Linux is not only used as a server by network operation and maintenance personnel. Linux can be used as both a server and a network firewall, which is one of the highlights of Linux.

Linux has the characteristics of open source code, no copyright, and many users in the technical community. Open source code allows users to tailor it freely, with high flexibility, powerful functions, and low cost. In particular, the network protocol stack is embedded in the system, and the function of the router can be realized after proper configuration. These characteristics make Linux an ideal development platform for developing routing and switching equipment.
