A Game Based Approach for Sharing the Data Center Network

Abstract

Current virtual datacenters in cloud computing have flexible mechanisms to partition compute resources but provide little control over how tenants share the network. This paper proposes a game based approach for sharing the network bandwidth between tenants. Leveraging network virtualization technology, we present a game model for virtual bandwidth allocation. In the game, the data center owner as a leader announces a price for bandwidth allocation that attempts to drive the tenant’s virtual networks to the social optimal solution, each virtual network as a follower chooses a willingness-to-pay to maximize its own profit. Experimental results show that the bandwidth allocation between tenants is efficient and fair.
