Abstract

A deep insight into the relationship between vCPU scheduling and I/O transmit in Xen was provided. Then an effective and lightweight recognition method, through which could identify the so-called NSVM (network queuing sensitive virtual machine) that was more vulnerable to the congestion in I/O transmit was put forward. Furthermore, a novel mechanism for resource assignment and scheduling called Diff-Scheduler was proposed. It could schedule the vCPU of the NSVM more frequently than other VM in different pools independently. Evaluations based on a prototype of Xen platform featured Diff-Scheduler show that the proposed mechanism significantly improves the network performance of VM. Specifically, comparing with the default mechanism of Xen, Diff-Scheduler proposed jointly enhances throughput, latency remarkably and ensures the fairness of resource allocation at the same time.
