In this paper we investigate the building of a virtual router platform that ensures isolation and fairness between concurrent virtual routers. Recent developments in commodity x86 hardware enable us to take advantage of the flexibility and wealth of resources available to a software router in order to build a virtual router platform. Using commodity x86 hardware we show that it is viable to run highly experimental and untrusted router systems along side a production router on the same hardware platform without sacrificing performance. We investigate the extent to which we can isolate a virtual router running experimental code from other virtual routers.
