  • REFRESH OF THE BINDING TABLES BETWEEN DATA-LINK-LAYER AND NETWORK-LAYER ADDRESSES ON MOBILITY IN A DATA CENTER ENVIRONMENT
    Publication number: 20210176135
    Abstract: A method for assisting communication of a source host upon movement from a first Data center (DC) to a second DC is disclosed. The method includes identifying that the source host has moved from the first DC to the second DC, ensuring that packets identifying a source as the source host in the second DC are copied to a control plane network element, and, for a first destination host identified in a first packet copied to the control plane network element and identified as a host that is not in the second DC, updating an Address Resolution Protocol (ARP)/Neighbor Discovery Protocol (NDP) cache of the source host by sending, to the source host, a first ARP message/unsolicited neighbor advertisement specifying a Media Access Control (MAC) address of an edge router associated with the source host in the second DC as a destination MAC address for the first destination host.

  • Load balancing with mobile resources
    Patent number: 9763135
    Abstract: In one embodiment, a method includes discovering at a network device, a change in a resource at a local network site, notifying a load balancer at the local network site of the change in the resource, dynamically updating a weight associated with the resource, and transmitting the weight from the network device to a mapping system configured for mapping endpoint identifiers to routing locators. An apparatus and logic are also disclosed herein.

  • Network device mobility
    Patent number: 9647923
    Abstract: According to one example embodiment, an EID-NOTIFY packet is defined for use with the Location/Identifier Separation Protocol (LISP). A first-hop network element may send EID-NOTIFY responsive to decoding a data packet from a previously undetected host on its subnetwork. A site network element may receive EID-NOTIFY, and send a MAP-REGISTER message to a mapping system. EID-NOTIFY may have substantially the same format as MAP-NOTIFY. This may enable the site network element to be removed more than one hop from the subnetwork.
