Research into two source-based control algorithms for Internet traffic flows

Abstract

TCP and UDP are the major applications over the Internet, the characteristics of them lead to different network transmission behaviors. Two source-based mechanisms are proposed in this paper to regulate TCP and UDP flows. One is the-congestion control mechanism, which uses TCP flows' congestion signal to regulate the flows at the source node. The other is the time slot mechanism, which is a time-sharing application to control their flow transmission, Based on the priorities of flows, different bandwidth proportions are allocated and differential services are provided for flows. Several scenarios are simulated to observe the transmission operations of these two mechanisms. Simulation results show some insights into two mechanisms. Moreover, the several simulation parameters that may impact the performance of these two mechanisms are summarized. (C) 2001 Elsevier Science B,V, All rights reserved.
