Vamshi Krishna Voruganti has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11677586
    Abstract: A first provider edge device may receive device information from a second provider edge device included in an Ethernet virtual private network (EVPN). The device information may identify a media access control (MAC) address and may indicate that the device is connected to the second provider edge device. The first provider edge device may receive data transmitted by the device and may determine, based on information included in the data, that the device has moved from the second provider edge device to the first provider edge device. The first provider edge device may generate a data packet including mobility information indicating that the device has moved to the first provider edge device. The first provider edge device may transmit, via a data plane of the EVPN, the data packet to the second provider edge device to permit the second provider edge device to update routing information for the device.

  • Publication number: 20230095253
    Abstract: Techniques are described for providing fast reroute for traffic in EVPN-VXLAN. For example, a backup PE device of an Ethernet segment is configured with an additional tunnel endpoint address (“reroute tunnel endpoint address”) for a backup path associated with a second split-horizon group that is different than a tunnel endpoint address and first split-horizon group for another path used for normal traffic forwarding. The backup PE device sends the reroute tunnel endpoint address to a primary PE device of the Ethernet segment, which uses the reroute tunnel endpoint address to configure a backup path to the backup PE device over the core network. For example, the primary PE device may install the reroute tunnel endpoint address within its forwarding plane and one or more operations to cause the primary PE device to encapsulate a VXLAN header including the reroute tunnel endpoint address when rerouting the packet along the backup path.
