Virtualization to build large scale networks

Abstract

There is not much research concerning network virtualization, even though virtualization has been a hot topic for some time and networks keep growing. Physical routers can be expensive and laborious to setup and manage, not to mention immobile. Network virtualization can be utilized in many ways, such as reducing costs, increasing agility and increasing deployment speed. Virtual routers are easy to create, copy and move. This study will research into the subjects of networks, virtualization solutions and network virtualization. Furthermore, it will show how to build a virtual network consisting of hundreds of nodes, all performing network routing. In addition, the virtual network can be connected to physical routers in the real world to provide benefits, such as performance testing or large-scale deployment. All this will be achieved using only commodity hardware.
