Optimization Technologies for Low-Bandwidth Networks
Iosr Journals, Randa Ibrahim Mohammed Ibnouf Eng · Figshare · 2015
One measure of the growing disparity between the developed and developing worlds is the speed of the Internet. For example, the speeds of connections from North America to Africa are slower than those to Europe by a factor of 50. The reasons for this disparity include the availability of Internet access only via slow satellite connections, and the lack of communications infrastructure in the remote parts of the world. Bandwidth and computing equipment are expensive as a result of weak currencies, high transport costs, small budgets and unreasonable tariffs. Bandwidth in some developing countries can be so costly that even their prime universities cannot afford speeds equivalent to the average western household with an ADSL connection. Thus universities and other institutions cannot afford a decent link, or are simply unaware of existing alternatives.This paper attempts to provide practical information on how to gain the largest benefit from existing connections to the Internet, by exposing readers to thelatest techniques to optimize the use of low-bandwidth network connections.This study has for the years 2005 and 2008 with the beginning of the implementation of the Sudanese Universities Network to measure the performance of the network. Byapplying optimization techniques, the effectiveness of available connections can be significantly improved. Access to more bandwidth will facilitate better exchange of scientific information, data and literature among researchers all over the world.
