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.

Abstract translation: 在一个实施例中，计算机网络中的交换机拦截到目的地目的地的分组，该分组具有目标的请求节点多播地址作为分组的目的地媒体访问控制（MAC）地址。 因此，交换机可以确定被请求的节点多播地址是否是交换机的交换机硬件表中的命中或未命中，并且响应于命中，用目的地目标的已知值重新写入目的地MAC地址 该表，并将数据包单播到目标目标。 在一个或多个附加实施例中，响应于未命中，并且响应于单个交换机架构，交换机在响应于未命中的同时丢弃分组，并且响应于多交换机体系结构，交换机可以计算 用于被请求的组播目的地的存储库交换机，并将该分组单播到计算的存储库交换机。
