Computer network principle teaching system based on libpcap

Abstract

The invention discloses a computer network principle teaching system based on libpcap, which can help students to improve the operational ability, understand typical computer network protocols and master computer network knowledge, thereby improving the teaching quality of computer network principle courses. The system comprises a driving layer module, a data link layer module, a neighbor subsystem module, a network layer module, a routing subsystem module, a transmission layer module and a Socket interface layer module. In combination with packet capture analysis, students are required to program by themselves to achieve typical computer network protocols, understanding and understanding of the students on the computer network principle are deepened in this way, and meanwhile the practical ability of the students is improved. According to the method, the object-oriented programming model is utilized, and a typical protocol separation mode is adopted, so that the overall realization difficulty is reduced, students can realize a single protocol step by step and gradually master the whole system, and the computer network principle is mastered.

Description

technical field [0001] The invention relates to the field of computer network technology and education, and more specifically relates to a teaching system of computer network principles based on libpcap. Background technique [0002] Contemporary computer technology is developing rapidly. In recent years, people have been paying more and more attention to cloud computing, big data and network security, and the development of these technologies is inseparable from the support of computer network technology. Proficiency in the principles of computer networks is a must for students of computer science and technology and related majors. However, the computer network system is huge and the structure is complex. Students have always felt that the course of computer network principles is difficult to master. Although colleges and universities attach great importance to computer network courses and increase experimental hours, most of them still focus on theoretical teaching, or jus...
