Generation Of Self-Similar And Long-Range Dependent Traffic And The Research Of TCP Congestion Control

Presently, Scale of Internet is becoming large increasingly, types of carried traffic are more and more. Internet gives great benefit and affect to people's living and working.However, in recent years, a series of test result show that network traffic flow is self-similar and long-range dependent (LRD), which break old basic suppose that network traffic flow is short-range dependent. Then, the conventional method has not been applied to these traffics. 95 percent of data flow use TCP/IP on Internet, TCP congestion control TCP is always an important problem, especially during recent network rapidly increasing. TCP congestion control & self-similar and LRD of network flow have been two hot research problems.This paper does some research on the theory of self-similar and LRD, and gain a method of generation of self-similar and LRD traffic, namely, the traffic is generated by using TV - Burst model of power tail distribution ON/OFF source. This paper use internationally universal simulation software NS-2 to do some simulations. Then, some performance analysis of TCP is done based on these traffics. At last, I do some improvement on TCP congestion control, which result to accord with this new network characteristic and improve network performance.
