While I was at Williams College and napster was just getting big (probably 4 years ago now) the school limited bandwidth consumed by the napster traffic specifically. They had some complex traffic shaping stuff they were using to accomplish this. In my estimation this is probably a pretty common thing at schools around the nation...

Second offense, same thing, third offense, it's 56K till the end of the semester. Unpleasant, yes. Although I've heard recently that there's a new program called NeoModus that lets users download from each other over a WAN - ie, the entire PSU network, all over PA - without affecting their 'internet' usage - since the bandwidth availability inside the internal network is of course much greater than that which has to pass through the NAP bottleneck to the outside world... this is all hearsay, of course, since I'm not in the dorms at PSU.. (I'm living in my parents' basement right now.. *sigh*.. but soon I'll be upgraded to cablemodem, which is at least a bit better than dialup...) -Danny --- Date: Thu, 13 Feb 2003 21:47:29 -0800 (PST) From: Brandon Dorman Subject: Re: FC: Kent State student paper says school will rate-limit P2P users To: declanat_private In-Reply-To: <5.1.1.6.0.20030213221001.016568b8at_private> (if posted, please delete my e-mail address.

Big bandwidth gets expensive. I would imagine it will be configured so that as long as max bandwidth isn't reached, traffic will be unrestricted. The prioritization simply sets the heavy bandwidth traffic such as P2P at a lower priority. If there is contention for the available bandwidth, the higher priority traffic goes first. This effectively slows down low priority traffic during peak times, while improving performance of higher priority traffic. During non-peak times, there will be no difference. --- From: "Yoder, Wm. Douglas" <yoderwat_private> To: declanat_private Message-ID: <3E4C8B16.9060900at_private> Date: Fri, 14 Feb 2003 00:22:14 -0600 The Milwaukee School of Engineering has been doing this for a year and a half. The school's bandwidth is paid for, in part, by a State of Wisconsin grant, which allows for internet access for educational purposes. The school has bandwidth-capped the popular P2P ports, and installed some queing software on some of the main campus routers. Before they did this, it took 5 minutes to check your email, even though the school had almost 25Mbps of bandwidth at that time. Now, things are much better, and the school only needs 18Mbps. The Computer Communications and Services Department doesn't make a point of telling the students about this (I had a friend who was a unix admin for the school). If a student complains, they are told "the Internet access is free for you, but the state is paying for it for educational purposes only. P2P is not an educational purpose", and that that is the reason for the bandwidth cap. If I remember correctly, the bandwidth cap for P2P services is about 5KB/s. -Doug Yoder Milwaukee School of Engineering Computer Engineering student --- From: "BobCat To: <declanat_private> References: <5.1.1.6.0.20030213221001.016568b8at_private> Subject: Re: Kent State student paper says school will rate-limit P2P users Date: Fri, 14 Feb 2003 01:24:50 -0500 (remove address please) : "In attempt to the curb Internet slowdowns and network instability ...

Lots of colleges are using various methods (packet shaping is common) to throttle student traffic. I know that Merrimack College (where I teach) and Babson College (where I used to teach) are doing this. The public reason is the limited bandwidth, but the target always seems to peer2peer, music file sharing, not other bandwidth hogs. I would guess the schools are worried about legal threats. In suport of this, I have seen access to student disk space shut off when the students are known to have software like kazaa on their laptops. This is certainly not a bandwidth issue. Someone may want to look at college IT outsourcing companies (like Collegis) to see if they do this at all client sites to see if they are a contributor to this trend or whether colleges are adopting this approach on their own. cheers, bob On Thu, 13 Feb 2003, Declan McCullagh wrote: >... > University officials want to stem bandwidth-sucking programs like Morpheus by > implementing packeteers, a combination of hardware and software that > prioritizes Web activity. ------------------------------------------------------------------------- POLITECH -- Declan McCullagh's politics and technology mailing list You may redistribute this message freely if you include this notice.
