1. Rhodes University - Department of Computer Science 1 Project Project: Re-establishing and improving the experimental VoIP link with the University of Namibia: A Case Study Supervisors Supervisors: Alfredo Terzoli and Mosiuoa Tsietsi By Ricky Ngandu g07n1084@campus.ru.ac.za

2. Rhodes University - Department of Computer Science 2 Background In 2004 a VoIP link was established between Rhodes University and the University of Namibia The link had a high packet drop rate due to an inconsistent internet line Low or no internet bandwidth at the University of Namibia When a link was established it had a poor voice transmission

3. Rhodes University - Department of Computer Science 3 Objectives: Re-establish VoIP link with the University of Namibia Improve the bandwidth availability through traffic shaping and quality of service (QoS) Possibly setup a VoIP based video conferencing facility using SIP (Session Initiation Protocol)

4. Rhodes University - Department of Computer Science 4 VoIP model

5. Rhodes University - Department of Computer Science 5 Approach of Study Understand the University of Namibia network Obtain in-depth knowledge on VoIP, methods of enhancing network traffic and understand the implementation process of VoIP Deploy VoIP Test live video over a VoIP link using SIP

6. Rhodes University - Department of Computer Science 6 Project Challenges For this project to work the following cannot be assumed: Reliable network Bandwidth is infinite To ensure that we have a reliable network, there will be a need to negotiate with UNAM’s ISP and UNAM’s computer service department

7. Rhodes University - Department of Computer Science 7 Deliverables Establish a fully working VoIP model Possibly establish video conferencing Possibly create a blueprint for connecting African universities together using video and VoIP

8. Rhodes University - Department of Computer Science 8 Future work The last two deliverables are possibilities which may not be completed in this project Video conferencing is essential for today’s communication needs and should be implemented Huge expenses are incurred on communication. A cheap solution would be one of the best things to happen to any educational institution’s budget. A blueprint for future implementations would be an asset
