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

Multi Protocol Label Switching (MPLS) is a core networking technology that operates essentially in between Layers 2 and 3 of the OSI model; for this reason, MPLS has been referred to as operating at Layer 2.5. MPLS can overlay existing technologies such as Asynchronous Transfer Mode (ATM) or Frame Relay, or it can operate in an entirely IP native environment; this can allow users to take advantage of existing Customer Premises Equipment (CPE) while making a move towards converging all network traffic, such as data, video and voice, at a pace that users can accommodate and afford. MPLS provides. its users a number of advantageous features such as traffic engineering, network convergence, failure protection, and the ability to guarantee Quality of Service (QoS) over IP. arabic 2 English 27

Abstract: In WiMAX networks, the biggest challenge is to overcome the effects of fading especially when nodes are mobile. The multipath nature of channel leads to ISI (Inter Symbol Interference) and the severity of ISI effects increases with bandwidth increase and this might get worse when nodes are moving . The radio link between the Base Station and Service Station/Mobile Station can be a LOS or it can be a NLOS. The environmental objects and features like buildings, weather conditions can severely obstruct NLOS signal. In this paper the effect of pedestrian multipath and node mobility in WiMAX network is studied under different codecs schemes in order to evaluate the effect of multipath channel fading when nodes are moving on the QoS parameters end to end delay, jitter, mean opinion score and throughput of a VoIP application. The obtained results showed that multipath fading with mobile nodes has sever effect on throughput and MOS value for all studied codecs and on the other parameters the effect varies depending on the implemented codecs. arabic 14 English 71
