A high performance network virtualization architecture with bandwidth guarantees

Virtualization technologies in cloud computing have been developing rapidly nowadays. One of their fundamental technologies is network virtualization. In order to increase bandwidth, link aggregation can be applied with network virtualization. It can balance the bandwidth of multiple virtual machines. In this paper, we purpose a high performance network virtualization model for multiple network adapters on KVM full virtualization with two types of link aggregation: network bonding and network teaming. Both types can increase throughput up to the number of network adapters in scenario 1 and 2. In Our work also integrates SLA, which is able to guarantee bandwidth of each virtual machine. In scenario 3, SLA bandwidth with both of link aggregation types provides throughput ratios for each network adapter of the two iPerf virtual machine servers at 80% and 20%. In conclusion, bandwidth guarantee is possible on KVM with network bounding and network teaming.
