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.
