Abstract
An example method includes sending a virtual output queue (VOQ) length of a VOQ to an egress chip. The VOQ relates to a flow routed through an egress port associated with the egress chip. The method also includes receiving fair share information for the VOQ from the egress chip, and enforcing a control action on the incoming packets based on the fair share information. An ingress chip and the egress chip can be provided in a VOQ switch. The control action is a selected one of a group of actions, the group consisting of: (a) dropping packets, (b) pausing packets, and (c) marking packets. The method can further include receiving VOQ lengths of corresponding VOQs from respective ingress chips, where the VOQs relate to the flow. The method can also include calculating respective fair share information for each VOQ, and sending the fair share information to the respective ingress chips.
