Virtual Switch Data Control In A Distributed Overlay Network

摘要

An approach is provided in which a hypervisor provisions switch resources on a network interface card, which includes a virtual switch and a physical port. The hypervisor invokes a switch control module on a virtual machine, which provides control information to one or more of the switch resources. In turn, one or more of the switch resources utilize the control information to direct data packets between a source virtual machine and a destination virtual machine over one or more virtual networks that are independent of physical topology constraints of a physical network.
