Patent ID: 8817653

Claim:
A method for detecting an irregular retransmission, the method comprising: receiving, by a processor, a packet trace from a packet monitor positioned between a sender and a receiver, the packet trace indicating an arrival time for a data packet transmitted between a sender and a receiver; identifying, by the processor, transmitted bytes and retransmitted bytes in the packet trace; upon identifying the transmitted bytes and the retransmitted bytes in the packet trace, determining, by the processor, time-rate pairs from the packet trace; plotting, by the processor, the time-rate pairs on a rate tracking graph; determining, by the processor, a correlation coefficient based on the rate tracking graph as plotted; and if the correlation coefficient is less than a threshold, determining, by the processor, that the packet trace indicates an irregular retransmission, wherein the irregular retransmission indicates a failure of the sender to reduce a rate of transmission during a retransmission.
