Automatic Global Upload Rate Limit

[bbbl67@yahoo.com]

Up until 1.8.5, there used to be an "Auto" setting for upload bandwidth, but it's gone now. Why? I found it useful sometimes.

uTP and Bandwidth Management (in Preferences, BitTorrent) replaced it.

Oh, okay, so how do I know when bandwidth management is working?

In the old automatic upload rate system, you'd see the rate cut-off bars on the graph being re-evaluated every 10 minutes (by default).

[Switeck]

There's no lines to show what bandwidth management thinks current max is...and you should still give uTorrent a set upper upload speed limit as well as other settings balanced to that to prevent overloads.

You will however see uTorrent auto-reduce download and upload based on other activity on the internet connection.

I understand what you're trying to say, but I'm one of those people that has an ISP that is utterly hostile towards bittorrents, and they have been rate-limiting torrents for a couple of years now. You can't get around it with encryption, because they are using Deep Packet Inspection techniques. You will see the ISP slowing the torrents to a crawl everyday at very specific times. At other times in the day, without the rate limit lines, I can't tell if it was my ISP that has determined my top speed for me (even though it was outside of throttling periods), or if it's my own uTorrent.

I am aware of Bell Canada ADSL ISP.

Yes, you would not be able to tell if uTorrent speeds were low because of ISP throttling or uTP screwing up.

Thanks, but I think I may have already been aware of this technique, and tried it already a couple of years back when it first started happening, because my settings were already setup exactly like this. I just may have forgotten where I had found it, or even that I had found it at all! It's likely that Bell has already patched up this loophole, because it no longer works.

Regarding uTP, I've read a few things about it, and it sounds like they are using UDP as the underlying protocol rather than TCP. However, it seems to be more than just a simple change from one type of TCP/IP-family transfer protocol to another. They say it can cooperate with the ISP to set transfer rates appropriate to the time of day, etc. How exactly do they do that?

in laymans terms, it backs off the connection when the line gets congested,

in "geek" it measures the amount of time taken for the packets to arrive and adjusts accordingly, or thats my understanding of it anyway
