The number of users adopting Tor to protect their online privacy is increasing rapidly. With a limited number of volunteered relays in the network, the number of clients' connections sharing the same relays is increasing to the extent that it is starting to affect the performance. Recently, Tor's resource allocation among circuits has been studied as one cause of poor Tor network performance. In this paper, we propose two scheduling approaches that guarantee proportional fairness between circuits that are sharing the same connection. In our evaluation, we show that the average-rate-base scheduler allocates Tor's resources in an optimal fair scheme, increasing the total throughput achieved by Tor's relays. However, our second proposed approach, an optimization-based scheduler, maintains acceptable fairness while reducing the latency experienced by Tor's clients.

Tor 电路调度的比例公平方法

采用 Tor 来保护其在线隐私的用户数量正在迅速增加。由于网络中的自愿中继数量有限，共享相同中继的客户端连接数量正在增加，以至于开始影响性能。最近，Tor 在电路之间的资源分配已被研究为造成 Tor 网络性能不佳的原因之一。在本文中，我们提出了两种调度方法，以保证共享相同连接的电路之间的比例公平。在我们的评估中，我们展示了基于平均速率的调度程序以最佳公平方案分配 Tor 的资源，从而增加了 Tor 中继实现的总吞吐量。然而，我们提出的第二种方法，一种基于优化的调度器，
