Abstract: Network devices perform multiple stage path resolution. The path resolution may be ECMP resolution. Any particular stage of the multiple stage path resolution may be skipped under certain conditions. Further, the network device facilitate redistribution of traffic when a next hop goes down in a fast, efficient manner, and without reassigning traffic that was going to other unaffected next hops, using multiple stage ECMP resolution.

Abstract translation: 网络设备执行多级路径解析。 路径分辨率可能是ECMP分辨率。 可以在某些条件下跳过多级路径解析的任何特定阶段。 此外，当下一跳以快速，有效的方式下降并且不使用多级ECMP分辨率重新分配将进入其他未受影响的下一跳的流量时，网络设备便于业务的重新分配。

Abstract: A network device, such as a switch, implements enhanced linked-list processing features. The processing features facilitate packet manipulation actions performed, e.g., by hardware or software processes. Hardware processes may run for egress ports, for example, to traverse the linked-lists to apply the packet manipulation actions on packets before sending packets out of the ports.

Abstract translation: 诸如交换机的网络设备实现增强的链表处理特征。 处理特征便于例如通过硬件或软件处理执行的分组操纵动作。 硬件进程可以为出口端口运行，例如遍历链路列表，以便在从端口发送数据包之前对数据包应用数据包操作动作。
