Offloading routing complexity to the Cloud(s)

Abstract—We propose a new architectural approach, Cloud-Assisted Routing (CAR), that leverages high computation and memory power of cloud services for easing complex routing functions such as forwarding and flow level policy management. We aim to mitigate the increasing routing complexity to the cloud and to seek an answer to the following question: “Can techniques leveraging the memory and computation resources of the cloud remedy the routing scalability issues? ” The key contribution of our work is to outline a framework on how to integrate cloud computing with routers and define operational regions where such integration is beneficial.
