First Claim
Patent Images
1. An apparatus implemented in at least one of a memory or a processing device, comprising:
- a first flow control module configured to send a first flow control signal based on data flow within a first flow control loop including (1) a first stage of transmit queues fanning into a second stage of transmit queues, (2) the second stage of transmit queues fanning into a physical link, and (3) the physical link; and
a second flow control module configured to define a second flow control signal based on data flow within a second flow control loop including (1) the second stage of transmit queues, and (2) the physical link, and excluding the first stage of transmit queues.

Abstract
In one embodiment, a method includes sending a first flow control signal to a first stage of transmit queues when a receive queue is in a congestion state. The method also includes sending a second flow control signal to a second stage of transmit queues different from the first stage of transmit queues when the receive queue is in the congestion state.
