Title: Software Defined Networks (SDN) Framework for Cyberattacks Resilience
Kelvin is pursuing his PhD at Nelson Mandela-African Institute of Science and Technology (NM-AIST). I am co-supervising him with Dr. Ali. His work is looking into building novel framework for building resilient network infrastructure.
Computer and communication networks in today’s society have become highly sophisticated and complex. In early days of traditional network, network devices configurations were done manually by system administrators. As the network size become increasingly large and using more dedicated and complex network devices, more configuration issues and challenges to the management of network are being introduced. This has been one of the major sources of networks (and in turn systems) failures and security vulnerabilities.

Challenges Of Computer Network Infrastructure In Acessing Electronic Information Resources In Academic Libraries
Musa graduated from The Open University of Tanzania. His work identified the computer network challenges hindering, and proposed solution to, digital library resources access.
It is seen that computer networking and e-resources access have been in use notably since 1950s and innovations and inventions of computer hardware, software and corresponding technologies have been taking place through these consecutive decades. Utilizations of these technologies in libraries vary considerably from developed countries to less developed countries, Tanzania being among them.
The paradigm shifting in libraries practices from only using printed information resources to using both printed and electronic information resources have necessitated librarians, computer scientists, and information technologists to take many initiatives in studying how network and networking infrastructures can enhance availability and access to e-resources by information seekers. The specific objective of this study was to identify challenges of network infrastructure installation, policies, pricing as well as assessing challenges of e-resources access in academic libraries in Tanzania.
Said Ramadhan Said - Masters (2017-2018)
Title: Solutions for ICT Accessibility to Persons with Visual Impairment at The Open University of Tanzania
Said graduated from The Open University of Tanzania. His work was a study which culminated in proposing a software framework for ICT accessibility to persons with visual impairment at the Open University of Tanzania.
​
The findings of the study indicate that OUT teaching and learning activities; management activities and communication use ICT thus causing barriers to non-ICT literates. For visually impaired barriers to accessibility were related to unavailability of ICT training opportunity and inaccessibility of online content. To measure the accessibility of the online content, Achecker tool was used. It was found that most of the ICT related solutions for ICT accessibility barriers are provided by an international standard organization. However, none of the System administrators had skills to incorporate these standards in developing accessible online content, resulting to visually impaired persons having no developed support systems.
2/ Teaching
OIT 117 – Data Communications and Networking I
​
I taught this course every year from 2007 to 2012 and again in 2017 and 2018 at The Open University of Tanzania. This was an introductory course aimed at providing the students with an overview of the concepts and fundamentals of data communication and computer networks. I covered topics such as Internet standards and organizations, key terms in computer networks, introduction to data communication concepts and techniques, network topologies, layered network models (OSI reference model, TCP/IP networking architecture) and their protocols, various types of networks (LAN, MAN, WAN) and their protocols, introduction to wireless networking concepts, and network applications.
OIT 215 –Data Communications and Networking II
​
I taught this course every year from 2007 to 2012 and again in 2017 and 2018 at The Open University of Tanzania. This was level 2 course on data communication and networking where I taught details of three key layers in the OSI model (i.e Data link, Network, and Transport) including design issues, error detection and correction, protocols, Ethernet, wireless LAN, routing algorithms, congestion control, network addressing and subnetting, Interior gateway routing protocols, TCP, UDP, and performance issues. I also introduced students to network security and network virtualization.
OIT 313 –Network Design and Administration
​
I taught this course every year from 2007 to 2012 and again in 2017 and 2018 at The Open University of Tanzania. The course covered the Top-Down Network Design methodology which provided practical and comprehensive guide to designing enterprise networks that are reliable, secure, and manageable. It involved campus LANs, remote-access networks, WAN links, and large-scale internetworks.
CS 348 –Network Switching and Routing
​
I taught this course in 2020 at The University of Dar es Salaam. It is a comprehensive 1-year course covering basic to advanced topic in network switching and routing. It covered bridging and switching, ethernet, network architecture, protocols, algorithms and routing technologies.
