Abstract:
The talk will give an overview of VLSP – our platform and testbed for experimenting with virtual routers and Software Defined Networks. Our experience with system-level virtual machines (e.g. Xen, VMware) plus software routers highlighted some serious issues. Our main requirements for a testbed, rather than using a hypervisor running a standard virtual machine and standard OS, explain why we built our own platform for testing and evaluating Software Defined Networks.
The background to the virtual routers is presented, plus an overview of the virtual routers platform. We show detail of the architectural elements, plus outline the research we have already done using the virtual router platform. Finally, the flexibility of the platform is presented, showing how we use the distributed in-built monitoring system to implement different VR placement algorithms and also build different distributed management applications.
