Abstract
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.
