Different Levels

Computer networks have evolved dramatically in recent years and consequently qualified and experienced network administrators are highly sought after, which in turn has led to the development of specialised computer networking courses at many universities. In this chapter, the authors investigate the use of network simulation tools as an alternative to be employed in computer networking laboratories. Network simulation tools provide students with the opportunity to freely experiment with virtual computer networks and equipment without the expensive costs associated with real networking hardware. The results of their research show that students appreciate the use of network simulators and see them as an effective approach to learning computer networking concepts and gaining the relevant experience. This was also confirmed by the actual performance of students who experienced different levels of exposure to networks simulators during their studies. The authors furthermore investigate the use of interactive, electronically assessed lab sessions, where students get immediate and interactive feedback while they are going through lab exercises. Their research shows that this approach not only releases the lecturer from less demanding students to better support weaker students, but that this will also lead to improved student performance and better student retention.

Network Metrics

This article aims to secure a routing mechanism by completing amendments in previously proposed efficient secure routing (ESR) protocols against networking layer attacks in mesh networking environments. Along with generating the tickets to prove the authenticity of communicating clients, each node proves the legitimacy of its succeeding node by computing the behaviour. The intermediate nodes selected for routing the data packets proves the legitimacy of each other by getting the passive acknowledgement process within a predefined time to live (TTL) time. Further, grey hole and black hole attacks are considered in the network simulation environment as they drastically affect the network metrics during the communication because of their severe attacking characteristics. The proposed mechanism is validated over conventional routing mechanisms against packet loss and network delay parameters in the presence of black hole and grey hole routing attacks.

Educational Literature

The article discusses of training future computer science teachers in computer networks based on network simulation. Analysis of scientific and pedagogical and educational literature has shown that in the training of computer science teachers, computer networks are studied in the aspect of information simulation of their structures, while simulation the processes of their functioning is not given due attention, despite the possibility of its use in the organization of training. Most educational institutions face organizational, technical and material difficulties when organizing training in computer networks on real equipment. The above-mentioned difficulties in training future computer science teachers in computer networks can be avoided by using network simulation. By network simulation, we mean reproducing a dynamic image of the main network components (network cables, switches, hubs, routers, etc.) and visualization the processes of their configuration and operation on the computer screen.
