Resilient campus network to support research and educational network in Ghana (case study of Accra Technical University).

Abstract

This paper describes how to setup a fully resilient design in a campus network to support Research and Educational Network in Ghana. The main idea of resilient topology for tertiary institutional campuses is to minimize downtime to the barest possible minimum. These down times usually happen during crashes and device upgrades. This paper describes how all critical devices are used twice to avoid having a single point of failure. Therefore, any single device can be turned off without significant disruption for the connected applications and users. Finally an appropriate resilient network that will support both students and staff research and collaborative works, with adequate bandwidth requirement to render the system scalable within the next seven years has been determined and recommended.
