  • Publication number: 20240125713
    Abstract: A method includes directing light at a first side of a semiconductor structure; detecting a first light intensity at a second side of the semiconductor structure, wherein the first light intensity corresponds to the light that penetrated the semiconductor structure from the first side to the second side; and comparing the first light intensity to a second light intensity, wherein the second light intensity corresponds to an expected intensity of light.

  • Patent number: 9548922
    Abstract: A method is provided in one example embodiment and includes receiving at a first network element a packet from a second network element; processing the packet at the first network element to obtain information regarding an identity of a virtual machine (“VM”) hosted by the second network element contained within the packet; and storing at the first network element the identifying information. The identifying information stored at the first network element is accessible by at least one third network element. In some embodiments, the first network element comprises a physical switch and the second network element comprises a virtual switch.

  • Patent number: 9531643
    Abstract: Techniques are provided for provisioning network resources for virtual machines. At a first switch device, a configuration request message is received from a virtual switch to provision virtual network segmentation resources for a virtual machine managed by the virtual switch. The first switch device provisions the virtual network segmentation resources for the virtual machine. The first switch devices sends to a second switch device a first synchronization message that includes information describing the virtual network segmentation resources. The second switch device is a peer of the first switch device. The first switch device also sends to the second switch device a second synchronization message that includes state information indicating that the first switch device is in an active state for servicing the virtual machine and that the second switch device is to be placed in a dormant state for servicing the virtual machine.
