The Tor network has its user grown by thousands every year. The increasing number of users around the world makes Tor become one of the widely used privacy networks today. However, as the number of Tor user increases, the performance of Tor degrades badly due to traffic is not fairly distributed. As a result, the Tor network does not provide a better quality of communication for all its users. To improve these problems, we proposed a simple method of dynamic circuit switching on the Tor application level to distribute the bulk and light traffic on Tor. We calculated the fairness indexes of transferred bulk and light traffic to observe any improvement and, compared our method with the default entry onion router algorithm. Our experimental results show the proposed method improves the distribution of traffic and achieves fairness of throughputs for all Tor users.
