  • IPV6/IPV4 resolution-less forwarding up to a destination
    Patent number: 9621581
    Abstract: In one embodiment, a switch in a computer network intercepts a packet to a destination target, the packet having a solicited node multicast address of the target as a destination media access control (MAC) address of the packet. As such, the switch may determine whether the solicited node multicast address is a hit or miss within a switch hardware table of the switch, and in response to a hit, re-writes the destination MAC address with a known value of the destination target from the table, and unicasts the packet to the destination target. In one or more additional embodiments, in response to a miss, and in response to a single-switch architecture, the switch drops the packet, while in response to a miss, and in response to a multi-switch architecture, the switch may compute a repository switch for the solicited multicast destination, and unicasts the packet to the computed repository switch.
