Building an operator CDN the virtual way

Hareesh Puthalath; Karl-Åke Persson; Bob Melander; Johan Kölhi; Victor Souza; Stefan Hellkvist; Jan-Erik Mångs

Virtualization has opened an exciting and powerful way to experiment and evaluate complex distributed systems. In this paper we describe the experiences and lessons learned from building a distributed operator CDN consisting of 260+ virtual machine nodes in a six blade server unit. This provided us with a flexible platform to analyze a caching architecture we were developing. We also discuss the impact of virtual networking and virtual software routers on hardware resources.
