Abstract
A packet forwarding apparatus has a path selection device used to generate a path selection signal for selecting a destination path from egress paths of an egress path group. The path selection device has a flow group based path selection circuit and a flow subgroup based path selection circuit. The flow group based path selection circuit sets the path selection signal based on a flow group into which a packet is categorized when a dynamic load balancing function is not applied to forwarding of the packet. The flow subgroup based path selection circuit sets the path selection signal based on a flow subgroup into which the packet is categorized when the dynamic load balancing function is applied to forwarding of the packet. Flows associated with the egress path group are categorized into flow subgroups, the flow subgroups are categorized into flow groups, and each flow includes packets with same tuple(s).
