The impact of packet reordering on the performance of TCP flavours is presented in this paper by analyzing four TCP flavours that are TCP-Reno, TCP-Newreo, TCP-SACK, and TCP-Linux. Thus, to do so an experiment is conducted based on simulation environment using Network simulator NS-2 version 2.33. The simulation results show that sending rate is decreased as a result of packet reordering phenomena; however, TCP-Linux performs better than other TCP flavours when there is more than one flow due to the large initial value of TCP-Linux slow-start threshold (ssthresh). These results demonstrate that packet reordering negatively affect the performance of TCP flavours. The finding of this paper can be summarized in that packet reordering may have a catastrophic effect on the performance of the TCP flavours, and the expected throughput from using these TCP flavours might not be achieved.
