Abstract

Abstract

Network virtualization is widely deployed in network experiment platforms and data center networks. As a key networking equipment in virtualized environment, the virtual router can build many virtual router instances to run different virtual networks. The key problem for a virtual router lies in how to schedule the packets into different virtual instances according to the virtual networks bandwidth requirement. In this article, a model is given to the scheduling problem and a dynamical weighted scheduling algorithm is proposed. The experimental results show that the proposed algorithm has superiority over miDRR algorithm in terms of the efficiency and the fairness.
