For those of you in the US using Comcast as your ISP, you'll know that they now have a feature called Powerboost available in the regions they serve. Basically, it allows people to have higher-than-rated throughput for the first few minutes of data transfer. After those few minutes, they're supposed to throttle back down to what their rated line speed is.
I'm having difficulty coming up with a solution to do traffic shaping on these kind of connections. Since the line speed isn't fixed, my guess was to set the traffic shaper to use the maximum possible speed as it's downstream limit. I guess I have a couple questions, more on the conceptual level: 1) Is there a way to remove all traffic shaping from the inbound channel of an interface...given you can't really do that anyway? Does setting the bandwidth value too high effectively do this? 2) By setting the bandwidth values for the WAN interface abnormally high, will the traffic shaper still re-order the packets as they leave the interface on the upstream channel? I would think that if tc could simply re-order packets, with a small queue maintained for lower priority traffic, then the throughput limits would not have to be defined...allowing the shaper to rise and fall with the Powerboost oddness. This idea is wholly unfounded, however, so please illuminate me. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
