Hyper-Switch: A Scalable Software Virtual Switching Architecture
Kaushik Kumar Ram, Alan L. Cox, and Scott Rixner
In virtualized datacenters, the last hop switching happens inside a server. In this article we describe the Hyper-Switch, a highly efficient and scalable software-based network switch that works alongside driver domains. Hyper-Switch outperforms existing virtual switches used in Xen and KVM, especially for inter-VM network traffic, and this performance will soon be critical in datacenters.
