  • Patent number: 11425044
    Abstract: This technology enables a dynamic host configuration protocol (“DHCP”) Layer 2 relay in a Virtual Extensible Local Area Network (“VXLAN”) overlay fabric. A host device broadcasts a configuration request, such as a DHCP discover, across an Ethernet virtual private network (“EVPN”) overlay fabric. The DHCP discover is intercepted by a VXLAN Tunnel End Point (“VTEP”) device with Layer 2 bridging functionality. The VTEP device selects a centralized gateway (“CGW”) device with Layer 3 relay functionality as a destination for the DHCP discover. The VTEP device encapsulates the DHCP discover with a unicast VXLAN header comprising the media access control (“MAC”) address of the CGW device and transmits the encapsulated DHCP discover to the CGW device, resolving the destination address associated with the broadcast. The CGW device transmits the DHCP discover to an Internet Protocol (“IP”) address associated with a DHCP server that is external to the EVPN overlay fabric.

  • Patent number: 11423095
    Abstract: Methods, systems, and computer storage media for providing action-recommendations (e.g., save action, collaboration action, and upload action) using cloud system operations in a cloud system. For example, action-recommendations are predicted using usage data of applications and communicated to a user (e.g., via a prompt) such that the user elects to perform or not perform the action-recommendation. In operation, usage data for an application and an action-recommendation profile are accessed. Determining that an action-recommendation should be generated is based on the usage data and the action-recommendation profile. The determination is further based on action scores and thresholds (e.g., save action, collaboration action, upload action). When the action scores meet certain thresholds, the action-recommendation is generated as a save-action-recommendation, a collaboration-action-recommendation, or an upload-action-recommendation.
