Re: [OK] Cox doesn't mess with Bittorrent traffic, does it?
I am starting to think that Cox is using Sandvine in a testing phase in certain markets, OKC being one of them. I personally know of four people that are noticing BitTorrent slowdowns (significant) on Cox in OKC. When I was running Cox and AT&T side by side for a few days, I started one torrent on my AT&T connection and was able to max out my connection with it. The download on Cox was stuck at 80KB/sec.
I have no proof that Cox is doing anything...just observations.

Easy to verify if you use utorrent, view the clients and if you see them connect and immediately disconnect, its sandvine or similar quality of service degradation service.

said by MarkyD :I am starting to think that Cox is using Sandvine in a testing phase in certain markets, OKC being one of them. Actually, I brought up the topic because I suspect that Cox is interfering with my connection.
I recently had the rare need to provide a file to my team via Bittorrent. This time around, I noticed all sorts of problems (individual upstream connections going to 0kB/s after 10 seconds). And all sorts of randomness, rarely able to even come close (not to mention sustain) my self-imposed cap of 30kB/s.
I would have suspected a problem with up my upstream path, but my FTPs are 100% rock solid. Back to Bittorrent... I tried downloading off of a public torrent server, and was able to download just great, but my upload throughput was weak and random.
Example FTP stats...
> 9558016 bytes sent in 140.65Seconds 67.96Kbytes/sec.
Has anyone from Cox answered the original question, or has a response been avoided so far? "Cox doesn't mess with Bittorrent traffic, does it?" |

»[CA] Packet Shaping, San Diego
I download IPFW and added the following firewall rule...
deny tcp from any to me 6881 tcp flags rst
...and ran another test. In a period of 5 minutes, the firewall rule detected OVER 2000 RST packets on the BitTorrent port.
I didn't run a packet sniffer on both sides of a BitTorrent connection to prove that fake RST packets are being generated, but I think I've proved to my own satisfaction that Cox is engaging in Comcast-like behavior. Even still, I want an answer from a Cox employee who can speak authoritatively on this.
The question, again: "Does Cox interfere, in any way, with BitTorrent traffic?" |

I think that you both have a good question for Cox, just you are asking it in different ways:
Assuming Cox is interfering with BitTorrent...
1] Are they doing this to partially curtail piracy on their network?
2] Or are they doing it to preserve more free bandwidth on their network? |
