Abstract:
1. A method comprising: a) receiving a data packet at an input buffer of a receiver, the input buffer associated with a first port; b) determining whether a number of data packets received at the input buffer of the receiver from the first port that are waiting to be switched to an output buffer of a network switch exceed a predetermined threshold, wherein the determining is performed by transmitting a second signal from the receiver to a packet queuing control (PQC); and determining at the PQC, based on the second signal, whether the number of data packets or an equivalent amount of data of the data packets received at the receiver from the first port that are waiting to be switched to an output buffer of the network switch exceed a predetermined threshold; c) based on determining that a number of data packets received at the input buffer of the receiver from the first port that are waiting to be switched to an output buffer of the network switch exceed a predetermined threshold, transmitting a first signal from the network switch to a station coupled to the network switch directing the station to terminate the transmission of data packets to the network switch; and d) transmitting an additional signal to the receiver if the number of data packets received at the receiver from the first port that are waiting to be switched to an output buffer of the network switch exceed the predetermined threshold, wherein the additional signal indicates that the data receive rate of the first port should be reduced.
