The use of the communication and information technology tools can aid students in their lab work to add more flexibility to the accessibility and providing of up-to-date higher education allowing students accessing knowledge anytime, anywhere which will facilitate the lifelong learning and provide accessibility to the curriculum and other students’ resources from anywhere at any time. Laboratory work by students in the information technology and engineering fields of study is a must requirement in all accreditation agencies and targeted employment places. This chapter demonstrates a project based learning technique that has been integrated with ordinary classes in computer network courses. The tools used in this study concentrates on the modeling and simulation of different aspect of computer networking that highlight different skills needed to any computer network engineer. arabic 8 English 53

In this paper a brief introduction to the concept of quality of service has been given. However, it mainly focuses on the classification of routing algorithms based on a number of different criteria like: protocols, structure, technologies in use, etc. And it concludes with a presentation of a common problem facing routing protocols, namely routing loops, and explained the known solutions to that problem. arabic 6 English 52

A denial of service attacks are usually employed to interrupt the system's activity by getting a large number of fake requests, which leads to slowing down and stopping information system or network operations. This paper outlines the basic principles of DDoS attacks, explains how DDoS attack works. The paper presents an experimental using OPNET simulation tool in which traffic from three different applications VoIP, FTP, and HTTP is used to make the practical model with a firewall shield to model and simulate DDoS over Internet. However, three scenarios have been developed to illustrate different aspects of the DDoS over networks. The results clearly demonstrate how firewalls can be configured to mitigate DDoS attacks
