The worst thing that happens is that they come back with a good price, good service and boom, I've found a new vendor. ------------------------------------------ I would suggest that no one should buy from vendors who get email addresses from NANOG or other technical mailing lists. It will only encourage them to do it more and ruin the value of the mailing list in question. You obviously haven't had the experiences that some have had with sales folks that use this method. Some are like the little Chihuahua that won't quit trying to hump your leg. No matter how many times you tell them you're not going to "do it" they keep trying. However, the company in this case did redeem themselves and I respect a company like that. scott

Sandvine, packeteer, etc boxes aren't cheap either. The problem is giving P2P more resources just means P2P consumes more resources, it doesn't solve the problem of sharing those resources with other users. Only if P2P shared network resources with other applications well does increasing network resources make more sense.

For instance, in our data centers, we have 1Gb uplinks to our ISPs, but guaranteed service subscription (a la CIR) to a certain rate which we engineer (based on average traffic volume, say, 400Mb), but burstable to full line rate -- if the bandwidth is available. Now, we _know_ this, because it's in the contract. :-) As a consumer, my subscription is based on language that doesn't say "you can only have the bandwidth you're paying for when we are congested, because we oversubscribed our network capacity." That's the issue here. I know full well the technical arguments of both sides of the issues, the economic issues, and the difference between a circuit switched network and a pcekt network, thank you. :-) $.02, - - ferg -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.6.3 (Build 3017) wj8DBQFHIhwoq1pz9mNUZTMRAlheAJ9KlFY73/+1dxQ7Q898reknG/MxHwCcDURl i0ARgqsvoxpPQkXFVCe9ons= =NGAf -----END PGP SIGNATURE----- -- "Fergie", a.k.a.

BitTorrent swarms have a deadly bite on broadband nets
by Sean Donelan 26 Oct '07

26 Oct '07

http://www.multichannel.com/article/CA6332098.html The short answer: Badly. Based on the research, conducted by Terry Shaw, of CableLabs, and Jim Martin, a computer science professor at Clemson University, it only takes about 10 BitTorrent users bartering files on a node (of around 500) to double the delays experienced by everybody else. Especially if everybody else is using "normal priority" services, like e-mail or Web surfing, which is what tech people tend to call "best-effort" traffic. Adding more network bandwidth doesn't improve the network experience of other network users, it just increases the consumption by P2P users. That's why you are seeing many universities and enterprises spending money on traffic shaping equipment instead of more network bandwidth.

"ARPANet Co-Founder Predicts An Internet Crisis" (slashdot)
by Paul Vixie 26 Oct '07

26 Oct '07

"Dr. Larry Roberts, co-founder of the ARPANET and inventor of packet switching, predicts the Internet is headed for a major crisis in an article published on the Internet Evolution web site today. Internet traffic is now growing much more quickly than the rate at which router cost is decreasing, Roberts says. At current growth levels, the cost of deploying Internet capacity to handle new services like social networking, gaming, video, VOIP, and digital entertainment will double every three years, he predicts, creating an economic crisis. Of course, Roberts has an agenda. He's now CEO of Anagran Inc., which makes a technology called flow-based routing that, Roberts claims, will solve all of the world's routing problems in one go." http://slashdot.org/article.pl?sid=07/10/25/1643248
