Abstract:
A method for controlling network bandwidth between a first node and a second node on a network, the method comprising the steps of:intercepting a data element transmitted from the first node to the second node, the data element comprising a data portion and a header portion, the header portion including an original window size;replacing the original window size in the header portion of the data element with a replacement window size, the data portion of the data element remaining unmodified; androuting the data element to the second node, the header portion of the data element being coupled to the replacement window size,the step of replacing further including the steps of:determining a current bandwidth and a threshold value of the data element;comparing the current bandwidth of the data element to the threshold value of the data element to determine a zone for the data element;identifying the replacement window size associated with the zone for the data element; andreplacing the original window size with the replacement window size.
