Abstract
The present application describes a system and method for a virtual machine to classify a packet. Once the virtual machine (VM) classifies the packet, it bypasses a hypervisor to enqueue the packet directly on a hardware transmission queue. The NIC will then verify that the VM classified and enqueued the packet correctly. If the packet was classified properly, it is transmitted over the wire to its destination. In this regard, the system and method provides a technique for verifying that the VM is enqueuing packets properly, while improving performance by allowing high-rate flows to bypass the hypervisor.
