Computer networks have contributed immensely to the development of educational systems globally by enabling timely access to information both in and out of the lecture rooms. This technology serves among its numerous uses as a bedrock of e-learning, e-library, telepresence and access to different research materials. The need for high network availability is therefore of paramount importance in an educational systems. This paper presents how high reliability, availability, and serviceability can be achieved in a campus network by the implementation of network architecture and standardised protocols that enable the network hardware to be more intelligent in load balancing and fail-over functionality in order to eliminate downtime during crashes and device upgrades. The approach enables a scalable and manageable network which allows devices from different vendors to interoperate.
