Hybrid clouds require scalable, high performance virtual networks (VN) to facilitate the resource interoperability among multiple clouds. However, current VNs in hybrid clouds face the following challenges: (1) Management complexity. The VNs in hybrid clouds need to support inter-cloud resource deployment with multi-tenancy and full address space virtualization, and therefore are complex to manage. Meanwhile, the VNs are vulnerable to failures due to their large scale. (2) Performance limitation. Hybrid clouds rely on the Internet to support inter-cloud data transmission. Therefore without a meticulous design, the inter-cloud VNs would suffer from a performance limitation introduced by the Internet, e.g., the intercloud bandwidth provided by the Internet is much lower and more fluctuant than that of the intra-cloud networks. To the best of our knowledge, most existing VN solutions cannot solve both of these challenges simultaneously.In this paper we introduce HCNet, a hybrid cloud virtual network management system. HCNet makes use of Software Defined Networking (SDN) and: (1) supports multi-tenancy and full address space virtualization on both Layer-2 and Layer-3 networks through the help of its elaborated packet processing pipeline, (2) leverages a dynamic load balance policy atop multiple inter-cloud gateways to achieve better performance on inter-cloud virtual networking, (3) maintains master-slave backup relationship based on paxos protocol to deal with controller outages. The experiment results indicate that HCNet achieves significant inter-cloud communication performance gain with respect to packet loss. Moreover, in presence of controller failures, HCNet is able to recover in about 5 seconds. |
