1. A computer implemented method comprising:

  • transmitting a specific data stream across a network from a first network node to a second network node according to a given output bandwidth, the specific data stream including normal packets (N-packets) which are processed sequentially;

    monitoring for an alarm signal from the second network node indicating a processing spike of the specific data stream, the alarm signal includes indication of an input bandwidth of the second network node;

    dynamically adjusting the output bandwidth in response to receiving the alarm signal with reference to the input bandwidth; and

    in response to receiving the alarm signal, transmitting an independent packet (I-packet) to the second network node, wherein the I-packet is a network packet processed independently of other packets at the second network node;

    wherein transmitting the I-packet is for replacing remaining packets from a processing queue of the second network node and for enabling the second network node to accomplish a processing task; and

    wherein dynamically adjusting the output bandwidth includes lowering the output bandwidth in order to decrease a processing queue latency of the processing queue.
