(English Abstract)
A cloud data center consists of thousands of servers connected by a hierarchical network. Each server runs multiple virtual machines owned by different clients. Since several virtual machines share network links, it is important to provide for per-client network performance isolation for quality of service guarantees. Unfortunately, existing network performance isolation techniques provide only per-flow isolation without the notion of clients and thus are not effective for a cloud data center. Moreover, these techniques lack scalability as they require non-trivial modification to legacy network equipment and the protocol stack of a guest OS. In this paper, we propose FS-VDE, a mechanism that assigns each client a weight and allocates it network bandwidth proportional to the weight. To do so, our approach performs outgoing traffic shaping and incoming traffic policing. FS-VDE can be widely adopted since it only requires limited modification to the host OS. We have implemented the proposed mechanism in Linux and measured the throughput of clients. Experimental results show that each client receives 99.4% and 96.5% of desired outgoing and incoming bandwidth, as specified by its weight, respectively. This result was achieved with only 5% of performance overhead.
