Re: Azu 2.5.0.0 RC4 Encryption Forced BUT STILL TMNET managed to
the newer bandwidth management devices use some sort of deep packet inspection, and can recognise torrent activity, even with encryption enabled. don't ask me how it works because I don't have the faintest idea. I guess torrent data transfer is easy to recognise because of the number of simultaneous inbound and outbound connections to any particular IP address.
i got shaped this afternoon on streamyx, and transfer slowed to about 15kb/s DL / 7kb/s UL on a well seeded 100% encrypted torrent from a private tracker.
tried to bypass the shaping with a free encrypted VPN to a US server and the speeds did return to normal. i guess that confirms that streamyx is shaping, since the international connectivity was obviously still there. but the VPN crapped out after 15 minutes. i guess you get what you pay for 
anyone got idea what device TMNet is using for the bandwidth shaping? or how to bypass it? |

| sashad,
Google for "netenforcer". It is just of the increasing # of devices able to do deep packet inspection. So, simple RC4 encryption just do not cut it anymore.
Like your experiment proves, real total encryption like VPN or SSH is the only way.
But I'm curious- u said ur speeds returned to normal after VPN to US server. Our latency to US already bad enough, so i'm curious 2 know what speeds were u getting with the free VPN ? |

VPN will never be throttled as doing 'deep fondling' on VPN packets may bring official charges of 'rape' by users. No box vendor will want to go there...
So, you get unfondled speeds all the way to US.
This is my major tiff with them about their throttling. They dont do dynamic throttling, they employ blanket throttling. Heck care if the gateway is unused, if day time, just simply whack. What I had expected is for the throttling to behave like a priority based service. So, I believe that he was using the VPN when there was no congestion on the Intl route, altho all of us were being capped to high heaven.
SSH dont grook. Unless you are able to use dynamic ports, they're already waiting to throttle you at the default port nos... And they employ 'wholesale throttling' if they see you there, even if you're trying to do normal browsing. Be prepared for 1.5 KB/sec/stream. Try it, and SSL too, you might not like the result.
I wont discuss what works, I'd just discuss what wont work so as to save you guys time...
