• 論文抄録 / 内容記述: The Tor network is an open network that helps its users defending against adversaries who performed traffic analysis and threatens the personal privacy and confidential security. Tor protects its users by preventing the sites they visit from revealing their physical location. This trust of services raises the number of Tor users daily, which 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 Tor's scheduler does not fairly distribute the traffics in Tor. In this paper, we highlight the problems in Tor performance due to scheduling design of Tor, which degrades the web and bulk traffic performances that multiplexes on a single TCP connection. To solve these problems, this paper emphasis on applying the simple method of active circuit switching on Tor application level, in order to distribute the bulk and web traffics through different TCP connections when congestion is detected in Tor. We evaluate our modified switching with the other default schedulers in Tor, such as vanilla and priority EWMA scheduler through a wide deployment network in shadow emulator. The experimental results show that our switching technique considerably offers stable improvement of traffic performance for all the web and bulk traffics.
