摘要: The characteristics of TCP and UDP lead to different network transmission behaviors. TCP is responsive to network congestion whereas UDP is irresponsible. This paper proposes two mechanisms that operate at the source node to regulate TCP and UDP flows and provide a differential service for them. One is the congestion control mechanism, which uses congestion signal detected by TCP flows to regulate the flows at the source node. Another is the time slot mechanism, which assigns the different number of time slots to flows to control their flow transmission. Based on the priority of each flow, different bandwidth proportions are allocated for each flow and differential services are provided. We use the ns-2 network simulator in which the different scenarios are set up to simulate the transmission operations of these two mechanisms. Simulation results show some insights of these two mechanisms. Moreover, we summarize the factors tat may impact the performance of these two mechanisms.
