Network availability is a key consideration in disaster planning, but it also has critical impacts on everyday life and work. For organizations, network downtime or sluggishness equates to business downtime, at considerable cost to organizations through inefficiency, lost sales, lack of critical data for decisions, and other harmful effects. First hop redundancy protocols (FHRP) are an essential tool for improving the availability of IP networks. In this paper, we evaluate the three particular protocols of FHRPs, namely the Hot Standby Router Protocol (HSRPv6), Virtual Router Redundancy Protocol (VRRPv3), and Gateway Load Balancing (GLBPv6) using GNS3 tools. The First Hop Redundancy Protocols have been implemented, tested, optimized, and compared to one another in terms of CPU Utilization, Traffic flow, packet loss and convergence time. The comparison indicates which protocol is best in which scenario and which is best among the three protocols.

This paper is presenting a discrete-event simulator written in C++ for modeling and simulating Fat tree network-on-chip systems based on MPLS technique. The simulator contains main component that construct butterfly Fat tree structure and other components that generate suitable number of switches and IP nodes (cores). The designed switch consists of input ports, output ports, input/output link controller, multi-buffers, crossbar switch, routing and arbitration components and MPLS unit. The correctness and the efficiency of the MPLS based Fat network-on-chip system is measured against well-known wormhole+ virtual channels technique. The produced results are clearly demonstrated the efficiency of the MPLS technique for future NoC designs. arabic 45 English 189

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
