Abstract:
Packet reordering in a short fixed period is considered in this paper. We believe that data will be transmitted dynamically and in parallel in the near future, which will require more frequent periodic packet reordering. This in turn will lead to unnecessary retransmissions and throughput degradation to the TCP (Transmission Control Protocol). There has been much research to improve the TCP performance with packet reordering, but the considered reorder intervals have been based on measurements on the existing Internet, and the short, fixed reorder intervals caused by the flexible transmission schemes have not been studied sufficiently. Therefore, in this paper, we vary the fixed reorder interval from within the Round-Trip Time (RTT) to over the RTT, and evaluate the communication performance of TCP NewReno and Cubic. From the simulation results, we show that the performance of TCP Cubic is highly affected by the packet reordering.
