African NRENs can expand educational opportunities across education sectors


Over the past three decades, the revolution in computers and telecommunications networks has created unprecedented changes in business, commerce, government, science, health care, and education. New jobs, new industries, an explosion in entrepreneurship, new modes of community building, increased learning opportunities, ease of access to timely information and global markets, and the ability of an extended community to interact closely across space and time: all are dividends of this revolution in network and information technology and the remarkable underlying Internet culture of change.
Yet the fruits of this Information Age are still unevenly distributed. This gap threatens to continue to cut off some populations from new opportunities. Access to new forms of education, good jobs, medical and health information, communication, and the chance to participate in the affairs of the broader society may be denied to them. For some individuals, technology brings the promise of inclusion, education, opportunity, wealth, and better health; for others, greater isolation and continuing poverty. Many look to universities and K-12 schools to bridge this gap.
Meanwhile, today’s Internet—the commodity or commercial Internet—has recognized a number of limitations. At the same time numerous opportunities and new possibilities have emerged. Some challenges, like the inability to provide workable “quality of service” or end-to-end performance guarantees needed for demanding applications such as telepresence (the current state-of-the-art videoconferencing technology) were outside the scope of the Internet’s original design goals. Challenges, such as dealing with today’s gargantuan amounts of traffic, exploding number of users and sites, privacy and security needs of users and institutions, and requirements for Internet addresses, are the consequences of unanticipated success.
Many new but challenging opportunities, like the delivery on demand of real-time, movie-quality, high definition television (HDTV) or even films over the Internet, as well as many new and experimental approaches to health care, are the product of extraordinary progress in a wide array of technology industries that are now convergent with the Internet’s evolutionary path. Other new applications and capacities are outside the focus of the commercial Internet. These innovative activities are supported best by research test-beds, the international fabric of national research and education networks (NRENs), which focus on the development and deployment of the next generation of Internet technologies.
The regular or “commodity” Internet was not designed to handle the huge amount of data transfer, the explosive numbers of users, or the interactive, media-rich applications commonly used today. For applications where reliability is critical and delay is unacceptable – applications such as real-time streaming events, access to remote scientific instruments, high definition video-conferencing, online gaming, and interactive immersive worlds and simulations – the commodity Internet is inadequate. Research and education networks were purpose-built by the research and education community to offer the flexibility, performance, speed, and advanced services that allow these applications to evolve and thrive.
NRENs serve many functions. They create leading-edge network capability for the international research community; they enable revolutionary Internet applications; they ensure the rapid transfer of new network services and applications to the broader Internet community; they provide a platform for sharing scientific (and other) applications and resources; they aggregate demand for bandwidth and thereby create “buying clubs,” drive down the cost of bandwidth; and they create social value by including communities outside their primary research university constituencies, like primary and secondary schools, libraries, museums, scientific and cultural institutions. In order to flourish, NRENs must focus on the technical dimensions of data networks and they must also attend to the human dimension, the creation of shareable expertise for support and collaboration across many fields of research and education.
