How much Bell's throttling affects our network and others


Notice the big "blip"? They throttle for almost 1gbps of traffic!

Re: How much Bell's throttling affects our network and others

Wow, thanks Gabe for those, very appreciated. That's like at least a third of what is usually used... this is quite insane.

And on that matter : We're all with you (obviously) on this one. I'm sure if you guys were to request something from us, we'd try as much as possible to help, as you've been helping us for years now.

Gabe, im curious. Some of us in #teksavvy feel the amount of peer2peer traffic is a bit low (before, and after). How is your graphs filter matching on p2p traffic?

What I find interesting about those charts is that P2P is a tiny fraction of the "70-90% of all Internet traffic" that the majors like to bandy about in the press. This, despite the fact that TSI is a favourite of P2P users.

the colored flow traffics are actually stacked. In other words UDP uses the most traffic, then Web, then P2P.

So there is more Web traffic on our network then P2P. Yet as you can see from the graphs, Bell does not only throttle P2P. It's affecting everything else.

Yeah thats what amazed me, everything is pretty much being modified, hence all the traffic spikes. Scary.

No, the traffic spikes are because the 'yesterday' graph has a different scale. The larger scale of the 'week ago' graph makes spikes less visible.

Note the peak traffic throughput a week ago was a pixel over 160Mbps while peak throughput yesterday was a little over 50Mbps. If these graphs are accurate, Bell has cut Teksavvy's traffic to about a third of its former volume even outside of the hours where P2P and encrypted traffic is degraded.

I question the accuracy of the traffic flow graphs, however. Slicing everything by two thirds 24/7 would have been noticed by everyone.

look at the scale... its like 1/3rd...

TSI needs to put out a press release on this first thing Monday.

Not only has Bell been less than honest about the percentage of P2P traffic but they've provided misleading information on what traffic is being filtered. This stuff is a PR goldmine as it demonstrates that Bell's public pronouncements can't be trusted.

If you send these graphs to the media, change the order around so P2P is at the bottom and therefore more clearly visible as a percentage. Better yet, make a separate pie chart showing what percentage was P2P a week ago and what percentage is P2P now.

What's all that undifferentiated UDP traffic, anyway?

Your transparency in how you do business is quite amazing, many could take a page out of your playbook called honesty.

Gotta love how all of the evil p2p traffic is eating so much bandwidth yet the graph shows it coming in as number 3. I was really surprised how little it really ate up.

Considering that many of us run frequent torrent up/downs the % of P2P traffic sure doesn't look like much, I would expect that the actual p2p traffic for Sympatico members is a fraction which reinforces the point that there was no need to do this aside from making money.

I run torrents 24/7 because my speeds suck, logically you would think if you gave people the ability to get what they want and then get out it would reduce overall traffic.

Instead of heavy download/upload for a few hours I now do moderate downloading for many weeks.

My guess would be gaming that is not being detected as gaming, VoIP, and other streaming/real-time media.

Yes but your graph has a separate color for DNS...

The three graphs obviously don't represent the same portion of your network. The first one is in the Gbps while the other two barely go over 100Mbps. If Bell only throttles P2P then your two colored graphs make no sense especially considering several reports of people experiencing full HTTP/NTTP/etc. speeds while P2P being stuck in the low 10's of kbps.

BTW, your "blip" is about 450-500Mbps, nowhere near 1Gpbs as you stated (or did you add in+out?).

It's a netflow graph. Only a certain percentage of the data is collected. But it still represents a global view of the network.

Sampled Netflow is pretty common but your graphing applications should be adjusted according to the sample rate you are using if you want the traffic levels to be more representative of reality. Also, Netflow is pretty lousy at identifying applications because it only knows about ports. I wouldn't trust it's P2P classification because BT/P2P apps tend to use ports all over the place... That's why they rely on DPI now because it goes further than just ports and looks at payload signatures to identify applications.

Gabe, thats what I was about to ask, considering users that are maxing their torrents, most of them are using private trackers that block common p2p ports such as 6881-6889. I know If I'm helping someone set up port forwarding I never use these ports simply because some trackers block them. So, is this true? does it only look at port numbers? If so i'd say this graph is trash.

Even if you combine all UDP traffic and all P2P traffic on those graphs, you're still at 50%, not 70-90% like Bell has tried to claim in the past.

I'm not so sure about that, I'd like to see a difference (before - after) graph if possible, so we can see exactly whats changed. Any chance we could get some raw charted data (perhaps using a better system then port identification), instead of a graph? then we could make our pie graphs and such for clarity.

Torrent data transfers use TCP, not UDP. A traffic analyzer that couldn't tell the difference between TCP and UDP packets would best be described as severely broken.

The only things that make heavy use of UDP are streaming media, VOIP (VOIP is really just a subtype of streaming media anyway), gaming and certain VPNs. Nothing else should come close to this level of UDP usage. I'm certainly not aware of any P2P apps that make extensive use of UDP for data transfer.

Not all torrent data is TCP, there is a good chunk that is also UDP, albeit your point still stands.

Good information to know. That would explain why there is that high amount of "UDP" showing on the graph, when streaming media has it's own category. Worth noting though is that even if you were to combine UDP and P2P together, that still isn't the "80-90%" Bell claimed being used by P2P

The graph "looks" the same but take a look at the numbers on the side. Thats the important part.

Last weeks UDP traffic alone is pretty close to the total amount of traffic flowing through the pipes now.

I feel bad for your call center people because I am sure they are fielding complains. Bring them a coffee or buy them lunch, I remember what it was like to be in there position.

Perhaps a breakdown of how TSI classifies traffic by protocol would be helpful to foster understanding.

The only way they can continue to say it without lying is if they don't know what traffic is going over their network. This would merely mean that they're incompetent rather than dishonest.

If they're saying that 70-90% of their network traffic is P2P when it is actually more like 20-30%, that is beyond incompetent.

In the end, most traffic is P2P - so no Bell is not lying.... Personally I rarely use broadcast functions....

In the end most traffic is P2P? Looks to me like UDP has P2P creamed by far...

I don't understand the comment about the first graph (the big blip). The big blip occurs between 2am and 12pm, outside of throttling hours. This only demonstrates that there isn't much demand during those hours, something the other graphs already confirm.

I think it's pretty amusing to see what portion of the traffic is P2P, since it proves that all the ISP's rationale for throttling are nothing but a bunch of lies and that we have been lied to from the very beginning.

Before looks like 20Megabits/s of P2P traffic vs current 5Megabits/s. Please correct me if I'm wrong.

Correction: I think these numbers need to be multiplied by something.
