摘要： Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding data traffic. In one embodiment, one or more functions are used to generate a result. A first portion of the generated result may be used as an index (e.g., ECMP index) for selecting a path (e.g., an ECMP path) from multiple possible paths for forwarding a packet. A second portion of the generated result, different from the first portion, may be used as an index (trunk index) for selecting an output port from multiple output ports associated with a trunk for forwarding a packet. In this manner, selected portions of the generated result may be used as indices, one for selecting a path and another for selecting a trunk port for forwarding packets such that the two indices are not the same and are not dependent upon one another.

摘要： Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding network data traffic. In one embodiment, a network device uses a rotate function to generate a rotated index (path index) that is used to select a path (e.g., an ECMP) path from multiple paths (e.g., multiple ECMP paths) for forwarding a packet. A network device may also generate a rotated index (trunk index) that is used to select an output port from multiple output ports associated with a trunk for forwarding the packet.
