  • Multiple network architecture providing for migration of devices
    Patent number: 8363666
    Abstract: In providing seamless migration of virtual or physical devices among networks of a virtual local area network (VLAN) such as one spanning multiple data centers, a same virtual anycast Medium Access Control (VMAC) is used for reaching default gateways in virtual and/or physical devices. Each network is typically configured such that source MAC learning for the VMAC should happen only for packets coming from the local default gateway. In this manner, when a device is migrated between networks of the VLAN, the same IP address and corresponding MAC address (typically still residing in the MAC cache of the migrated device) can be used to reach the local default gateway.
    Type: Grant
