Abstract:
1. A first network switch comprising: a first queue configured to (i) store first frames transmitted to the first network switch from a second network switch, and (ii) store second frames transmitted to the first network switch from a third network switch; a first port configured to (i) receive the first frames and the second frames from the first queue, and (ii) transmit the first frames and the second frames from the first network switch; a second port configured to (i) receive third frames transmitted to the first network switch from the third network switch, and (ii) transmit the third frames from the first network switch; and a first control module configured to, based on whether the first queue is filled above a threshold, send a first message to the third network switch to assert flow control for the second frames including adjusting a transmission rate of the second frames from the third network switch to the first network switch, wherein the first message instructs the third network switch to assert flow control for the second frames and not for the third frames.
