Transmission Rate Control Utilizing Chaotic Nature of Coupled Oscillators

Abstract

The TCP global synchronization problem is a phenomenon that packet losses or window control actions of different flows are synchronized. It causes degradation of the utilization of network bandwidth. RED is a well known approach to avoid this problem. However, discard of packets occurs in some probability even if they are in low-rate flow, and it might be unfair. In this paper, we propose new transmission rate control by using chaotic nature appearing in coupled oscillators. Our control can avoid the synchronization problem despite no use of random numbers and improve the network utilization.
