Self Similarity Effect of RTT and RTO in Network Congestion Control Mechanism

Round Trip Time (RTT) behavior of TCP causes self similarity. In Network traffic we observe Multi fractal nature due to RTO. The mechanism of fast recovery and fast retransmits improved and reduces the performances in network traffic. It is difficult to suggest an appropriate RTO algorithm for TCP, which mostly affect data transfer delay and congestion control. In general TCP transmits number of packets in the ON period and OFF period is approximately equivalent to RTT behavior in the network data flow. In this paper we shows self similarity between short RTT and high RTT also focus on RTT and RTO behavior. We also observe Role of RTT behavior, when load is high in network which causes Heavy-tailed effect. We simulate by taking different scenario in each scenario we put some CPEs and routers and put the result in this paper. We carried out the simulation using NetSim6.2..
