Abstract:

In order to avoid the network performance degradation due to the burst characteristics including Internet self-similar traffic, etc. , a mathematical model of loss fractal regulator controlling the self-similar traffic is pro- posed. The performances of the regulator including the queue length and the delay are analyzed, and the influences of the introduction of the regulator on the end-to-end delay, the total packets loss and the average loss rate are dis- cussed. Then, the relationship between the upper bounds of the above-mentioned performance indexes and the pa- rameter of self-similar traffic are investigated. Moreover, the buffer minimum of the loss fractal regulator at the maxi- mum average loss rate is obtained. The above-mentioned results provide a useful reference to the evaluation of con- gestion control scheme and traffic management scheme of self-similar traffic and to the design of parameters of the loss fractal regulator
