Thus we + propose a configurable parameter that sets the refill interval + accordingly. + +Motivation and Background: + + In Tor there exist multiple token buckets on different logical levels. They + all work independently. They are used to limit the up- and downstream of an + onion router. All token buckets are refilled every second with a constant + amount of tokens that depends on the configured bandwidth limits. The very + coarse-grained refill interval of one second has detrimental effects. + + First, consider an onion router with multiple TLS connections over which + cells arrive. If there is high activity (i.e., many incoming cells in + total), then the coarse refill interval will cause unfairness. Assume (just + for simplicity) that C doesn't share its TLS connection with any other + circuit. Moreover, assume that C hasn't transmitted any data for some time + (e.g., due a typical bursty HTTP traffic pattern). Consequently, there are + no cells from this circuit in the incoming socket buffers. When the buckets + are refilled, the incoming token bucket will immediately spend all its + tokens on other incoming connections. Now assume that cells from C arrive + soon after. For fairness' sake, these cells should be serviced timely -- + circuit C hasn't received any bandwidth for a significant time before. + However, it will take a very long time (one refill interval) before the + current implementation will fetch these cells from the incoming TLS + connection, because the token bucket will remain empty for a long time. Just + because the cells happened to arrive at the "wrong" point in time, they must + wait. Such situations may occur even though the configured admissible + incoming data rate is not exceeded by incoming cells: the long refill + intervals often lead to an operational state where all the cells that were + admissible during a given one-second period are queued until the end of this + second, before the onion router even just starts processing them. This + results in unnecessary, long queuing delays in the incoming socket buffers. + These delays are not visible in the Tor circuit queue delay statistics [1]. + + Finally, the coarse-grained refill intervals result in a very bursty outgoing + traffic pattern at the onion routers (one large chunk of data once per + second, instead of smooth transmission progress). This is undesirable, since + such a traffic pattern can interfere with TCP's control mechanisms and can + be the source of suboptimal TCP performance on the TLS links between onion + routers. + +Specific Changes: + + The token buckets should be refilled more often, with a correspondingly + smaller amount of tokens. For instance, the buckets might be refilled every + 10 milliseconds with one-hundredth of the amount of data admissible per + second. This will help to overcome the problem of unfairness when reading + from the incoming socket buffers. At the same time it smoothes the traffic + leaving the onion routers. We are aware that this latter change has + apparently been discussed before [2]; we are not sure why this change has + not been implemented yet. + + In particular we need to change the current implementation in Tor which + triggers refilling always after exactly one second. Instead the refill event + should fire more frequently. The smaller time intervals between each refill + action need to be taken into account for the number of tokens that are added + to the bucket. + + With libevent 2.x and bufferevents enabled, smaller refill intervals are + already considered but hard coded. This should be changed to a configurable + parameter, too. + +Conclusion: + + This proposal can be implemented with moderate effort and requires changes + only at the points where the token bucket operations are currently + performed. + + This change will also be a good starting point for further enhancements + to improve queuing times in Tor. I.e. it will pave the ground for other means + that tackle this problem. + + Feedback is highly appreciated. + +References: + + [1] Karsten Loesing. Analysis of Circuit Queues in Tor.
