Cloud computing allows individuals and organisations to remotely lease storage and computation resources as needed. For such remote access to computational resources to work efciently, there is a need for well-developed Internet infrastructure to support reliable and low-delay delivery of trac. By carrying out the month-long Internet measurement campaign, this paper investigates the hosting situation and latencies in the public sector of ve African countries.

Results of the study show that a large percentage of the public sector websites across the countries are hosted in cloud-based infrastructure and are physically located in America and Europe. Analysis of delays shows signi cant di ferences between local and remotely hosted websites, and that latencies are signfi cantly lower for countries that host CDN nodes. The results also suggest higher delays for local websites that are accessed circuitously.

Deep Diving into Africa’s Inter-Country Latencies

This clearly has negative consequences for the residents of Africa but also has implications for organisations designing future networked technologies that might see deployment in the region.

This paper presents a measurement campaign methodology to explore the current state of the African Internet. Using vantage points across the continent, we perform the first large-scale mapping of inter-country delays in Africa.

Our analysis reveals a number of clusters, where countries have built up low delay interconnectivity, dispelling the myth that intra-communications in Africa are universally poor. Unfortunately, this does not extend to the remainder of the continent, which typically suffers from excessively high delays, often exceeding 300ms.

We find that in many cases it is faster to reach European or North American networks than those in other regions of Africa. By mapping the internetwork topology, we identify a number of shortcomings in the infrastructure, most notably an excessive reliance on intercontinental transit providers.

With increasing demand for videos, streaming media, and for services such as cloud computing in Africa, broadband performance, and specifically how users experience performance, becomes increasingly important. In order to meet a growing demand for digital content, mobile operators across the continent have extensively invested in increasing capacity by investing in undersea cables, as well as in terrestrial fibre networks. Mobile LTE networks provision is expanding as well but remains insufficient to cover remote and rural areas.
