| Abstract(in English) | The efficient utilization of network resources is the important aim of Congestion Control. In TCP Vegas, the sender controls the data transmission by measuring the variation of RTT. Therefore, the packet losses are reduced and the efficient network utilization is achieved. About TCP Vegas, We have focused on 2 problems. The first problem is that the data throughput decreases when the Ack Path is congested. About this problems, we have proposed the SCC(Separated Congestion Control) that distinguishes the Data Path congestion from Ack Path congestion by measuring RTD(Relative Time Delay) variation, and controls the each Path congestions separately. The second problem is that the TCP Vegas can't follow the rapid change of network congestion. About this problem, we have proposed the SCA(Speedy Congestion Avoidance) that change the window size drastically when the network load is improper. |
