摘要：

A media streaming server can be implemented on a virtual machine for the ease of resource management. However, simply running a media streaming server on a virtual machine has two problems; the duplicate data in file caches of virtual machines and the performance degradation caused by the virtualization overhead. In order to resolve these problems, this paper proposes a high-performance media streaming architecture based on KVM. First, we implement a shared cache among virtual machines in order to eliminate the duplicate cached data. Second, the sendfile() operation is offloaded to the hypervisor to reduce the virtualization overhead in I/O operations. Our evaluations with D-DASH datasets show that the performance of a media streaming server in the proposed architecture is increased by up to 30% as compared to that of the conventional media streaming server that simply runs on a virtual machine.
