What is the AVU ? Experience

Who we are ?

The African Virtual University (AVU) is an innovative educational organization established to serve the countries of Africa. The objective of the AVU is to build capacity and support economic development by leveraging the power of modern telecommunications technology to provide world-class quality education and training programs to students and professionals in Africa. After a successful pilot phase, AVU has been transformed from being a project of the World Bank to an independent reputable Inter-governmental organization based in Nairobi, Kenya with over 57 Learning Centers in 27 African countries

Today : 68 learning Centers in 30 African Countries

What is the AVU ? Experience

What we doThe African Virtual University is working in collaboration with African Universities to identify the most essential program needed for Africa’s development. Upon identifying the programs the AVU partner with best universities in the world to developing content and delivery through our network to African students, professionals and civil servants


The avu technology model and bandwidth challenges l.jpg
The AVU technology Model and Bandwidth Challenges Experience

The technology model is responsive to the mixed mode delivery and pedagogical models utilizing a Learning Management System (based on WebCT) and satellite based content delivery network (VSAT) for video, online and Internet access.



Technology model l.jpg
Technology Model Experience

The AVU Learning Resources :

  • Digital Library : ( http://www.avu.org/dlibrary.asp 2 live servers -Jo-USA and nairobi )

  • WebCT : ( http://64.106.243.70/webct/public/home.pl , Jo-Burg and USA )

  • Interwise : ( http://avu.interwise.com/avu/ Canada and USA )


The avu technology model and bandwidth challenges9 l.jpg
The AVU technology Model and Bandwidth Challenges Experience

  • Cost of Bandwidth in Africa

  • Bandwidth Management problem

  • There is none ICT and Bandwidth policies in most of African Universities .

  • Most of National Telecom have unreliable Internet Access

  • The existing Bandwidth is not well managed .

  • Most of Universities Campus Network are not well design

  • Power failure

  • LAN Design

  • Technical skills in Linux field

  • Migration from windows to linux or open source software


Bandwidth solution and initiative l.jpg
Bandwidth Solution and Initiative Experience

  • Decision Makers Meeting in Kigali -2003

  • Vcs and ICT heads conference

  • Outcomes : Bandwidth consortium (The Partnership for Higher Education in Africa contracted the AVU in July of 2004 to investigate the possibilities of reducing the international bandwidth costs for Partnership supported universities by consolidating the universities’ bandwidth needs to achieve economies of scale, greater bargaining leverage and command volume discounts )

  • The African Connectivity survey ( www.atics.info )

  • Today with a support of partnership ( Carnegie Corporation of New York, The Ford Foundation, the John D. and Catherine T. MacArthur Foundation, and The Rockefeller Foundation ) , the AVU has established a Bandwidth Management Unit in Nairobi ( cut down bandwidth price from $10 /kbps/month --> $ 2 /kbps/month


Bandwidth solutions and initiatives l.jpg
Bandwidth Solutions and Initiatives Experience

  • Workshop on BM at Decision Markers Level and Technical level to enforce policy and Bandwidth regulation within the Universities :

  • Francophone sites : November 2005 ( http://www.techfranco.net )

  • Anglophone sites : Abuja and Nairobi September 2006

  • The AVU has tailored its VSAT solution to provide substantially lower pricing at approximately one-third of the cost paid by institutions of higher education for dedicated bandwidth.


The avu learning centers bm solution l.jpg
The AVU Learning Centers BM Solution Experience

  • Integrated the Use of Automatic playback ( recorded all live session which students can use any time )

  • Local webCT Miror servers wich synchronize tonight with Jo-Burg and Washington servers , students are able to access course and resources on their Local server

  • Local proxy Squid on the campus network

  • Enforce Bandwidth Management policy within campus

  • Assist University in Re-designing the local network using DNS caching and text based browsing such as ( http://www.loband.org/loband/main link ).

  • Modify web cache tools as wwwoffle

  • Thin Client Technology


Current pilot research project l.jpg
Current Pilot Research Project Experience

A key aspect of the AVU ‘s mission is to increase access to quality higher education opportunities across Africa . The traditional residential University model currently adopted by most universities in Africa is unable to meet either current or projected demand . Therefore , there is a need to extend access outside the universities physical campus by developing high quality Open and Distance Learning capacity within AVU Partner Institutions, including those that make use of new technologies for e-learning where appropriate .

The Main Question is : How to expand the reach of the web , e-mail , and other learning resources in Africa ?


Off line web browsing e mail and voice to mail technology l.jpg
Off line web browsing e-mail , and Voice to mail Technology

  • On going Two main Pilot Projects :

  • Nairobi Kenya with eGranary ( off line web browsing )

  • Dakar office with three sites :Senegal ( Saint-louis ) Mali and Burkina-faso on asynchronous communication technology

Way forward l.jpg
Way forward wireless link with wizzy digital

  • The AVU with Senegalese Ministry of Research will start from November 2006 a real case studies in one Senegalese village to proof the concept

  • The AVU BMU will still cut down price and provide Internet access

  • Internet Survey In Africa will have a key role to play in next few years

  • Work about the Business Model for rural area and Universities .
