Multi-campus ICT equipment virtualization architecture for cloud and NFV integrated service

We propose a virtualization architecture for multi-campus information and communication technology (ICT) equipment with integrated cloud and NFV capabilities. The aim of this proposal is to migrate most ICT equipment on campus premises into cloud and NFV platforms. Adopting this architecture would make most ICT services secure and reliable and their disaster recovery (DR) economically manageable. We also analyze a cost function and show the cost advantages of this proposed architecture, describe implementation design issues, and report a preliminary experimentation of NFV DR transaction. This architecture would encourage academic institutes to migrate their own ICT systems located on their premises into cloud environments.
