Network end users to pull down 2 gigabytes a day, continuously?
by Thomas Leavitt 18 Jan '07

If this application takes off, I have to presume that everyone's baseline network usage metrics can be tossed out the window...

Better get yourself a non-capping ISP... I am one of Venice' beta testers. Works like a charm, admittedly with a 20/1 Mbs ADSL2+ connection and a unlimited use ISP. Even at sub-DVD quality the data use is staggering... Venice Project would break many users' ISP conditions http://www.out-law.com/page-7604 OUT-LAW News, 03/01/2007 Internet television system The Venice Project could break users' monthly internet bandwith limits in hours, according to the team behind it. It downloads 320 megabytes (MB) per hour from users' computers, meaning that users could reach their monthly download limits in hours and that it could be unusable for bandwidth-capped users. The Venice Project is the new system being developed by Janus Friis and Niklas Zennström, the Scandinavian entrepreneurs behind the revolutionary services Kazaa and Skype. It is currently being used by 6,000 beta testers and is due to be launched next year. The data transfer rate is revealed in the documentation sent to beta testers and the instructions make it very clear what the bandwidth requirements are so that users are not caught out. Under a banner saying 'Important notice for users with limits on their internet usage', the document says: "The Venice Project is a streaming video application, and so uses a relatively high amount of bandwidth per hour. One hour of viewing is 320MB downloaded and 105 Megabytes uploaded, which means that it will exhaust a 1 Gigabyte cap in 10 hours. Also, the application continues to run in the background after you close the main window." "For this reason, if you pay for your bandwidth usage per megabyte or have your usage capped by your ISP, you should be careful to always exit the Venice Project client completely when you are finished watching it," says the document Many ISPs offer broadband connections which are unlimited to use by time, but have limits on the amount of data that can be transferred over the connection each month. Though limits are 'advisory' and not strict, users who regularly far exceed the limits break the terms of their deals. BT's most basic broadband package BT Total Broadband Package 1, for example, has a 2GB monthly 'usage guideline'. This would be reached after 20 hours of viewing. The software is also likely to transfer data even when not being used. The Venice system is going to run on a peer-to-peer (P2P) network, which means that users host and send the programmes to other users in an automated system. OUT-LAW has seen screenshots from the system and talked to one of the testers of it, who reports very favourably on its use. "This is going to be the one. I've used some of the other software out there and it's fine, but my dad could use this, they've just got it right," he said. "It looks great, you fire it up and in two minutes you're live, you're watching television." The source said that claims being made for the system being "near high definition" in terms of picture quality are wide of the mark. "It's not high definition. It's the same as normal television," he said. -- "Private where private belongs, public where it's needed, and an admission that circumstances alter cases." Robert A.

How big a network is routed these days?
by John Smith 17 Jan '07

17 Jan '07

Hello, my organization is considering PI addresses as a way to multihost. Having read the archives regarding disadvantages and alternatives, my question is how big a network must one have to be reasonably sure the BGP routers will accept the route? regards, JS

IPv6 section of ARIN Number Resource Policy (Sec 6.5.1.1.c)
by Nicolás Antoniello 17 Jan '07

17 Jan '07

Hi, This question is about the IPv6 section of ARIN Number Resource Policy Manual. >From the manual (Section 6.5.1.1.c): ----- 6.5.1.1. Initial allocation criteria c. Plan to provide IPv6 connectivity to organizations to which it will assign IPv6 address space, by advertising that connectivity through its single aggregated address allocation ----- We have a problem with this policy and we would like to know if any other ISP experienced the same... The problem raises when a RIR assign a /28 prefix (for example) to an ISP which has 3 internet links with 3 different carriers (tier 1 carriers, for example) using BGP publications. Acording to ARIN (and most other RIRs) policy, the ISP must advertise through all the 3 links the /28 without the possibility of dissagregation. The problem with this policy is that by doing this, the ISP loses control of the traffic, not being able to distribute the traffic over the 3 different links. A /28 prefix may have a lot of incoming traffic associated to it, so I believe the dissagregation (subnets) of the prefix should be allowed by the policy. What do you think? Do you have a similar problem? Thanks, Nicolas Antoniello.

Comment spammers chewing blogger bandwidth like crazy
by Thomas Leavitt 16 Jan '07

16 Jan '07

A friend of mine operates a blog at seeingtheforest.com, and he pays for traffic over a (fairly minimal) cap. He posted this comment recently: http://www.seeingtheforest.com/archives/2007/01/eating_bandwidt.htm Eating Bandwidth Last month something ate up a tremendous amount of bandwidth at Seeing the Forest, costing me a lot of money. So now I regularly check bandwidth use. Why has 209.160.72.10, HopOne in DC, been eating a HUGE amount of bandwidth? Gigabytes! What are they doing? (I banned them.) Why has 220.226.63.254, an IP in India, been eating a tremendous amount of bandwidth? What are they doing? Why has 195.225.177.46, an IP in Ukraine, been eating a tremendous amount of bandwidth? What are they doing? Why has 62.194.1.235 AND 83.170.82.35 AND 89.136.115.220 AND 62.163.39.183 AND 212.241.204.145, all from the /same company/ in Amsterdam, been eating a TREMENDOUS amount of bandwidth? What are they doing? Why is 206.225.90.30 and 69.64.74.56 and Abacus America Inc.eating a TREMENDOUS amount of my bandwidth, *** One of the comments said: Yeah, I've seen a huge bump in my blog's traffic, I haven't figured out what they're doing, but it ate like 4Gb of bandwidth last month. Now that you mention it, I checked last month's stats and yep, there's 209.160.72.10 producing 62% of my blog traffic. I did a little checking around the web and they're an obvious spam host. Banned. *** They also chew up a lot of CPU (comment filter code). At few times, myself, I've had to simply take code offline that was getting hit too heavily... seems like the IPs (and their ilk) listed above are good prospects for a "bad behavior" blacklist, at a level below that of "collaborative spam filter" (which doesn't prevent traffic or CPU cycles from being consumed). Given the volume of traffic mentioned, this must be a real problem for some hosts and networks... although, on the other hand, if their marginal use rates are high enough, they might actually be making money off this.
