Nowadays, university campus networks are architecturally designed following the traditional approaches where network devices are interconnected and are fully responsible for critical management decisions within the network. The devices in this traditional setting are configured by IT managers and network administrators. The number of devices connected to campus network is growing rapidly which makes manual configuration tedious and complex, especially considering the heterogeneous nature of these devices/services and Bring Your Own Device (BYOD) concept. This makes management of traditional network and configuration of these devices according to predefined policies inefficient and difficult respectively. This work therefore proposes the use of Software Defined Networking (SDN) framework as a tool for the management of campus network where network-wide rules are incorporated into the network. SDN is a new network paradigm for network management as it provides a programmable network platform through a programmable device (controller). Our framework employs more controllers to handle the heterogeneous nature of the present day campus environment for proper management of users and services and allocation of different network functions across the various infrastructures based on predefined policies. Implementing this proposed framework will undoubtedly yield flexible campus network management, efficiency of data transmission within the network, better network performance and security and also guarantees network evolution.

The proposed framework is hoped to be implemented in the campus of University of Uyo, Uyo, Nigeria. University of Uyo, Uyo has three campuses located within the metropolis, which makes it a good environment to implement the SDN framework. A database for all users and their corresponding devices will also be created and combined with users and access control policies to form the operational instructions for the network devices and infrastructure. The results will be flexible management and troubleshooting of network problems, efficiency of data transmission within the network, better network performance, reduction on administrators' overheads and cost, deployment of new technologies/ideas and better network security.
