Leveraging SDN and NFV for Provisioning Quality Network Infrastructure for Filipino Public Schools

ICT in education plays a role in encouraging and improving the creativity and critical thinking of students. In the Philippines, public high schools suffer from slow and intermittent internet connection which can negatively affect the quality of education that the students get. With the help of Software Defined Networking and Network Function Virtualization, we propose a local caching system to alleviate the effects of the aforementioned problem. This solution is remotely configurable and automatically scaling which lessens the need for a network administrator to maintain the system. The local caching system can operate between two modes, Hot and Cold. The system's two modes are tested and compared with each other. Experimental results show that the Hot mode reacts 42 seconds faster to changes in the internet connection while the Cold mode reacts slower but uses fewer resources overall. The automatic scaling is also tested and the results show that our system uses half the number of cores compared to an overprovisioned setup when the load is low.
