Towards Network Virtualization Management for Federated Cloud Systems

The federated cloud system provides the ability to integrate, manage, and use third-party resources from multiple institutions and combines the resources into one infrastructure. A virtual network management system is needed to supporting a seemingly infrastructure where services can be deployed on-demand and across different network domains. We present our work on designing and implementing an integrated system to enable virtual network services across federated clouds. We also propose a novel mechanism to enable network stitching via translating VLAN tag dynamically. The service can be partitioned on hosts across different network domain using different underlying layer-2 or layer-3 network technologies. This paper also provides the results of performance measurement from the implementation based on real production networks.
