RE: Comcast blocking p2p uploads

Has anyone (any lawyers here on the list?) investigated the legality of this action? With the FCC eliminating common carriage limits on ISPs, it seems that blocking traffic to/from particular IP addresses, etc., is acceptable. But from this description of Comcast's activities, it appears that they are using active measures to interfere with their customers' actions (fooling their customers' equipment into believing the machines at the other end have terminated the interactions). Could not this be construed as violating DMCA and a dozen other laws that have been invoked against malicious hackers?

I live in Atlanta and have seen this happening for about the 3 months, but I have friends in the suburbs that have (or had) no issues. I imagine they have been deploying their traffic shaping in more and more headends. Here is some actual operational details: It is reported that Comcast is using an application from Sandvine to throttle BitTorrent traffic. Sandvine breaks every (seed) connection with new peers after a few seconds if it's not a Comcast user. This makes it virtually impossible to seed a file, especially in small swarms without any Comcast users. Some users report that they can still connect to a few peers, but most of the Comcast customers see a significant drop in their upload speed. The throttling works like this: A few seconds after you connect to someone in the swarm the Sandvine application sends a peer reset message (RST flag) and the upload immediately stops. Most vulnerable are users in a relatively small swarm where you only have a couple of peers you can upload the file to. Only seeding seems to be prevented, most users are able to upload to others while the download is still going, but once the download is finished, the upload speed drops to 0. Some users also report a significant drop in their download speeds, but this seems to be less widespread. Worse on private trackers, likely that this is because of the smaller swarm size Although BitTorrent protocol encryption seems to work against most forms of traffic shaping, it doesn't help in this specific case. Comcast is making no effort to determine if the traffic they are blocking is legal or not. No one blocks all web traffic because some sites have illegal content or questionable/undesired material. Personally I think this is inappropriate behavior for an ISP and I hope it causes a mass exodus of Comcast customers. -Scott -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Clinton Popovich Sent: Friday, October 19, 2007 3:02 PM To: 'Steven M.

240/4
by Randy Bush 19 Oct '07

19 Oct '07

vince, thanks for your presentation on 240/4. i agree with it all. two points do not hard-code address boundaries and special addresses, as we are likely to regret doing so. two sub-lessons, ula and any other bright ideas. "Those who cannot remember the past are condemned to repeat it." -- George Santayana my first thought on how to use it revolved around the idea that the devices inside my site are more diverse than those on the transit internet. therefore, if i can use 240/4 internally, certainly we will all be able to transit it. where this died was the realization that, if i want to transit 240/4, i am expecting all the devices in *your* network to be able to handle 240/4, which is not reasonable. so i guess i come down on the private use side of the how-to-use decision. i would be interested in hearing counter-arguments. again, thanks for the preso and the work. and i presume my ciscos will soon be able to handle 240/4 at no additional hardware cost. :) randy

Anyone else having major difficulty with service with ICG/Level3 circuits in Ohio/Cleveland? We've had a circuit down for 10 hours and just two hours ago they notified us that they're having a major outage in our region and have not provided __any__ further information. TIA, -Drew

Re: 240/4
by BELLEVILLE Ray 18 Oct '07

What ever happened to pushing on the traditional class A owners to free up their address space? I can't help but think that the issue has always been mis management of the early assigned address blocks. Look at Nortel's block for instance... How many addresses are actually reachable directly from the internet? /22 subnets as a standard block with 100 addresses assigned.... They MAY have had an argument 8 years ago when they had 120K employees, but at 25K now, its a bit ridiculous. Hundreds of addresses per employee? How many other blocks are unallocated? V6 is a nice idea, but it only deals with the symptoms, not the cause. ----- Original Message ----- From: owner-nanog(a)merit.edu <owner-nanog(a)merit.edu> To: nanog(a)merit.edu <nanog(a)merit.edu> Sent: Wed Oct 17 18:41:39 2007 Subject: RE: 240/4 > the other point as was mentioned later in the thread is that > this buys you very little in terms of time before v4 is gone. On average, it buys everybody very little time. But that assumes that 240/4 is being released as a general solution for everybody. This is not the case. We want to release 240/4 as a solution for those organizations that are in a position to control enough variables to make it useful. For those organizations, 240/4 space could buy a LOT of time, maybe even years. And for the rest of us, the IPv4 addresses that are NOT used by those organizations, do indeed buy only a little extra time. But the point is that we are not gods. We cannot foresee all the variables. We cannot engineer a set of solutions that will work for everybody. Therefore, even if 240/4 only gives us a few extra months before IPv4 is exhausted, it is still worthwhile because it is likely to help some more organizations get their IPv6 transition completed before hitting the brick wall. Since the value of the Internet, IPv4 or IPv6, is in the near universality of access, it is to the benefit of everyone's bottom line for more organizations to complete the transition to IPv6 before IPv4 runs out. We cannot cop out on releasing 240/4 just because it is no magic bullet. How would you feel if your arguments against 240/4 and other half-measures resulted in them not being carried out. And then we hit the brick wall of IPv4 exhaustion and some businesses start to lose serious money? --Michael Dillon P.S. and how will you feel if those businesses trawl the record on the Internet to discover that you, and employee of one of their competitors, caused 240/4 to not be released and thereby harmed their businesses. You will be explaining in front of a judge. We should do everything we can to remove roadblocks which would cause IPv4 to run out sooner, or would cause some people to delay IPv6 deployment.

more-specifics via IX
by Bradley Urberg Carlson 18 Oct '07

18 Oct '07

I have a few customers' customers, who appear at a local IX. Due to the MLPA-like nature of the IX, I hear their prefixes both at the IX and via my own transit customers. I normally use localpref to prefer customer advertisements over peers' advertisements. There is a customer's customer who is advertising more-specifics at the IX (and using a different source AS, to boot). I can think of a couple ways to prevent hearing these, but thought I should ask for suggestions first. -Bradley
