What is SR-IOV based Virtual Network Sharing about?

The network, similar to the CPU and memory, is a critical and shared resource in Cloud. However, unlike the CPU and memory division strategy, virtual network bandwidth should be allocated according to the payment and needs of tenants. Different tenants may have different network demands for VM. This paper proposed a receive side network allocation mechanism under NIC hardware virtualization environment. We use two bandwidth control methods -(1) Control the Interrupt Throttle Rate (maximum interrupt number per second) of each VM. (2) Control the packet fetching rate using the TBF (Token Bucket Filtering) algorithm. As SR-IOV has become an industry standard of network sharing with a lot of advantages, It reduces the unnecessary context switch overhead and efficiently improves the bandwidth utilization on the basis of providing the sharing of I/O devices. We implement our algorithm on SR-IOV based environment. We evaluate the network performance of our algorithm. The result shows that the algorithm proportionally divides VM bandwidth according to what we specify without reducing the network efficiency largely.
