The aim of this diploma thesis is design and implementation of experimantal data network central management in convergent network technology laboratory. This diploma thesis is devided into several chapters. Management network fundamentals are described in introduction. Actually used experimental network is analyzed in the second chapter. Design and implemantion of web modular information system are presented in third part. Solution of central management network system is summarised at the end of this thesis.

International literature suggests that curriculum changes that have occurred in higher education globally over the last two decades, more specifically the shift from subject-based curriculum to integrated curriculum have been perceived by many academics as having affected their work with regard to course designing, teaching and assessment. Studies of academics’ response to such changes have argued that the way academics perceived these changes and the meanings they made of them influenced the implementation of these curriculum changes. This case study investigates lecturers’ perceptions of how one curriculum reform, the introduction of the Credit Accumulation and Modular Scheme (CAMS) in higher education in Rwanda, has affected lecturers’ work. One of the aims of the study was to analyse how lecturers understand CAMS and the changes it has introduced in their work. A second aim was to analyse how these perceptions and changes are negotiated in their teaching practices. Sixteen lecturers from Kigali Institute of Education were interviewed. Analyses of lecturers’ accounts of their teaching experiences revealed that lecturers espoused the intended changes that CAMS introduced in their work. However, although they claimed that the changes have affected their teaching and teaching arrangements- course designing, teaching and assessment- in actual practices many of them have not always managed to shift their thinking. CAMS requires lecturers to function in teams. However, although they have been trying to do so many of them have not managed to work out how to make more substantive changes to the way they think about the knowledge to be taught, their actual teaching and assessment practices. They have tried to keep boundaries of their disciplines while CAMS requires them to integrate their teaching.

The main objective of this research is to build an interest based peer – to – peer network which is structured yet non-DHT. Maintaining DHTs is a complex task and needs substantial amount of effort to handle the problem of churn. So, the major challenge facing such architectures is how to reduce this amount of effort while still providing an efficient data query service. The rationale behind choosing non- DHT based interest based network is that users sharing common interests are likely to share similar contents, and therefore searches for a particular type of content is more efficient if peers likely to store that content type are neighbors. We have used a mathematical model based on modular arithmetic, specifically residue class (RC), to design a two-level structured architecture. To the best of my knowledge, there does not exist any such work that has used this mathematical model.

Software development is a growing part of many businesses today. The software development approach that is used to develop new software may have a positive or negative impact on the efficiency and quality of the final software product. The objective of this thesis was to propose a refined software development approach and to test it empirically. The software development approach is comprised of three main subcomponents: development style, development architecture, and technical documentation. The software development approach was applied in a case study in cooperation with Ericsson. At the completion of the case study, questionnaires were administered to Ericsson employees to evaluate the success of the software development approach. The results showed that the quality of the software product was high and Ericsson was pleased with the result. The results indicated that the development approach helped the case study be successful in some of the researched areas. The end results suggest that the proposed software process has the potential to be successful in other projects of a similar type and structure.
