(English Abstract)
A virtual network is a kind of a logical network, and several virtual networks shares common physical resources. Therefore, compared to implement a physical network, a virtual network has a merit to be efficiently implemented in cost. A virtual router is a key component to implement virtual networks. Recently, researches of virtual routers on high performance commodity HW have been conducted. To support stable virtual networks, each virtual router does not affected by other virtual routers on the same physical platform. Generally, server virtualization techniques can be used to support isolation among virtual routers. However, the virtualization technique shows low I/O performance due to virtualization overhead. Because routers have executed many I/O operations to receive and transmit packets, the I/O overhead in virtualization should be avoided to implement high performance virtual routers This paper implements the Xen-based virtual router for isolation among routers, and reduces the virtualization overheads using SR-IOV to improve the I/O performance. And we show the performance effects by SR-IOV through an experiment. Also, we measure and analyze the performance of our virtual router. In here, We certificate a fact that the routing process and multi-core environment are reasons of the low network performance in the virtual router. This fact will be a foundation to develop some methods for network performance improvement in the virtual router.
