We also show that Conflux introduces only slight tradeoffs between users’ anonymity and performance. Through live measurements and a whole-network evaluation conducted on a scalable network emulator, we show that our approach offers an improvement of approximately 30% in expected download time for web browsers who use Tor bridges and for streaming application users. Moreover, Conflux significantly improves the experience of users who watch streaming videos online. Because it enhances the load-balancing properties of the network, Conflux considerably increases performance for clients using low-bandwidth bridges. In this paper, we present Conflux, a dynamic traffic-splitting approach that assigns traffic to an overlay path based on its measured latency. With the introduction of bridges-unadvertised Tor routers that provide Tor access to users within censored regimes like China-low-bandwidth Tor routers are becoming more common and essential to Tor’s ability to resist censorship. When clients use a low-bandwidth router, their throughput is limited by the capacity of the slowest node. We observe that one reason why Tor is slow is due to low-bandwidth volunteer-operated routers. While it has grown in popularity, Tor has a variety of performance problems that result in poor quality of service, a strong disincentive to use the system, and weaker anonymity properties for all users. Tor is the most popular low-latency anonymity network for enhancing ordinary users’ online privacy and resisting censorship.
