Methods and apparatus for destination based hybrid load balancing within a switch fabric

摘要

In some embodiments, an apparatus includes a switch module configured to receive an order identifier of a first data packet from a first stage of a multi-stage switch. The switch module is configured to receive an indicator of an available capacity of the first module of a second stage of the multi-stage switch fabric, and an indicator of an available capacity of a second module of the second stage of the multi-stage switch fabric. The switch module is configured, when the order identifier is assigned, to direct the first data packet to the first module of a second stage of the multi-stage switch fabric when the available capacity of the second module is lower than the available capacity of the first module. The switch module configured, when the order identifier is unassigned, to direct the first data packet to the second module when the available capacity of the second module is higher than the available capacity of the first module.

1. An apparatus, comprising:
a processor configured to be operatively coupled to a memory and that is configured to execute a switch module; and the switch module configured to receive an order identifier of a first data packet from a first stage of a multi-stage switch; the switch module configured to receive an indicator of an available capacity of a first module of a second stage of the multi-stage switch, and an indicator of an available capacity of a second module of the second stage of the multi-stage switch; the switch module configured, when the order identifier is assigned, to direct the first data packet to the first module when the available capacity of the second module is higher than the available capacity of the first module; the switch module is configured, when the order identifier is flexible, to direct the first data packet to the first module when the available capacity of the first module is above a threshold.
