This paper presents the development of next generation e-learning systems for real-time video, voice conferencing and streaming technology over secure socket layer (SSL) IPv6 in campus environment. Development of the V2oIP e-learning systems has contributed a significant value to distance learning. The aim of this study is to design real time interactive learning systems over SSL IPv6 for next generation network. This study shows the process and development of e-learning systems with V2oIP technology. Based on the results of this study, it is successfully develop e-learning systems with V2oIP technology over SSL IPv6 for distance learning system. From the result analysis, there is no significant difference between V2oIP SSL IPv6 and V2oIP SSL IPv4 performance issues. It also shows that IPv6 with difference Operating System (OS) has generated low usage RAM and CPU performance. The advantages of using V2oIP e-learning system to the universities are: i) able to manage students’ industrial training remotely; ii) postgraduate supervision from other region; iii) reduce operational costs; iv) manage to conduct research activities remotely and v) to provide an element of security (SSL) over IPv6 technology. Therefore, implementation of V2oIP e-learning system over SSL IPv6 (next generation network) is able to create mobility and a secure environment for undergraduate and postgraduate students.

Abstract The maintenance of existing software can account for 60 percent of all effort expended by the resources used in the system development life cycle. To improve the situation, analysts must design systems that are easy to use and maintain at the early stage of the development process. At the design phase, an object-oriented system (o-o system) is decomposed into subjects.... The maintenance of existing software can account for 60 percent of all effort expended by the resources used in the system development life cycle. To improve the situation, analysts must design systems that are easy to use and maintain at the early stage of the development process. At the design phase, an object-oriented system (o-o system) is decomposed into subjects. Each subject is decomposed into classes. A maintainable o-o system is a system where the change affects a less number of subjects. In this work, maintainability metric is proposed. This metric measures the localization of a change in a subject at the early stages of the development process during the analysis and design phases. This metric seems to be a good indicator of the quality of a system at the early stages. Read More Read Less

Abstract Dynamic scheduling on multiprocessor system is mostly for real-time applications. When allocating real time task to a processor, the network topology paid more attention. Hypercube and Mesh connected systems are well known topologies that can be implemented in the tightly coupled architecture. Hypercubes are used to have several useful properties such as high degree of connectivity, fault tolerance, low diameter... Dynamic scheduling on multiprocessor system is mostly for real-time applications. When allocating real time task to a processor, the network topology paid more attention. Hypercube and Mesh connected systems are well known topologies that can be implemented in the tightly coupled architecture. Hypercubes are used to have several useful properties such as high degree of connectivity, fault tolerance, low diameter etc.. In this paper, the outperforming Buddy R/ T [1], Stacking algorithms and Deferred Earliest Deadline First(DEDF) algorithms [2] have been analyzed. DEDF algorithm uses hypercube architecture. A modification of DEDF algorithm has been suggested for hypercube systems. We are introducing new window called Available Processor Time Window (APTW) for processor allocation. By using this window, the processor utilization can be improved and the deadlines of most of the tasks can be met. So, we assure that, the performance is noteworthy and better than the earlier proposed DEDF algorithm for a wide range of workloads. Read More Read Less
