back to article Virgin Media introduces P2P throttling

Virgin Media will for the first time target peer-to-peer traffic for throttling on its cable network, joining most DSL broadband providers. In a phased introduction due to be completed by next summer it will cut the bandwidth available to peer-to-peer protocols and Usenet at peak times, for all customers. Until now the firm …

    Well.....

    ....that'll be me off to another provider. How can you charge so much and then have the bare faced cheek to throttle. At least with BT Infinity you get a 10meg upload and only have to pay 27.99 a month. With Virgin they pretty much force you to have three services to get the 50MBit down to a near tolerable price but still much more than the competition.

    Only problem with BT infinity is the cap on how much you can download, ~500GB a month.

    Mine is the one with the two BT Lines and a bonded line in the pocket.....

      You're right...

      It's ridiculous they can assume all p2p traffic is sharing copyrighted material and even if it's true they have no right to throttle your connection.

      Why pay for internet if the isp can control what you download, how, and where you download from?!

        Not all P2P traffic is illegal!

        Just 99.999%

        This tired old argument about the 'legitmate' uses of P2P is just FUD. Two examples are usually trotted out - World of Warcraft upgrades and Linux ISOs which account for an infinitesimally small proportion of P2P traffic. Besides, anyone with sense grabs the latter from an FTP/HTTP mirror where they experience 10-100x the speed.

        Only the most desperate of freetards (when did we stop calling them thieves?) describe 'bittorrent' as a means to download anything but stolen content. Stop pretending that you're an innocent bystander who is being caught in the crossfire, it's just embarrassing.

          Virgin still provide mirrors of all the major linux distros on the old blueyonder address. Making the downloading of iso's and updates a fast business.

          Maybe you should consider what life will be like when every song ever created as an mp3 can be stored in a memory device that anyone can afford. Add to that, internet speeds of 10s or 100s of Gb/s. How do you possibly think that today's rules on what can and can't be shared between individuals can be controlled to the level the media industries want? It will be like trying to monitor the thoughts of everyone on the planet.

        OK, apart from you downloading your linux distributions and maybe iPlayer, 4OD etc pretty much everything else using torrent is copyrighted material and as for them having the right, of course they have as long as it's in the contract and you have signed that contract then they have the right.

        Now then, it ISN'T right of course but given that Virgin (and pretty much every ISP) sells "Unlimited" broadband that they have no hope of supplying they have to find some way to make sure that most users get a useable broadband connection most of the time

        @Tigra 07:"It's ridiculous they can assume all p2p traffic is sharing copyrighted material"

        P2P hammers networks whatever you're sharing, doubles the traffic (if you aim for a 1.0 ratio) and avoids any attempt to cache that traffic. P2P is almost a DDOS on network infrastructure.

        Copyright infringement is a totally different issue.

      5. The Avangelist

        nobody said anything about copyright

        Peer 2 peer capping has nothing to do with materials you are downloading. It is a matter of data and overheads.

        If you go on the sole assumption that it is whether Warner or Miramax are upset you are watching poor dvd rips you're quite mistaken.

        That would be reputation. From this side of the fence, who in their right mind would want to sign up to an ISP that has no problem shafting its customers whose only crime is using the service they paid for. (I presume you're aware that downloading 1 hour of HD content per day uses around 45 GB).

        Oh and there's that thorny issue known as PHORM - you'd have thought that the prospect of the UK taxpayer having to pay Virgin's unwritten fines might just cheese off a few people. But hey, as current Virgin customers obviously care nothing for privacy (or reduction in public services just to pay government fines), they're unlikely to change ISP, so your original premise is probably correct.

What, exactly, would be the point of moving from an ISP because they have started throttling P2P traffic only to move to another ISP who's been throttling P2P traffic for ages?

      look before you leap

      Before changing look into it carefully, the cap is for restricted speed at peak times for 30 days not the hours as on Virgin.

      1. leexgx

        speeds

        quite sure BT hidden Monthly cap is around 100GB (if you do it over 2-3 months) very sure on BT option 3 as my friend was getting billed for going over 100GB an month on an 2-3mb connection lol

        do consider you can do around 50-100GB an Day on virgin and not get shafted as much (not that i am asking you lot to do that thought as i like my 50MB fast as it is) yes you do have day limits but not that bad all they are doing is lowering the speeds for users that send to much (50MB) and slowing speeds down for 10mb and 20mb depending on download amount

        bout time they uped the upload speed for 10mb users (256KB upload before cut back) as when that was nocked back 75% it was like 96kb {8-9KB/s} to slow for torrent's to work correctly and other services at the same time (like using the internet) as they need 128kb (or 10-15KB/s} to work (not an issue if your on 20mb as upload cut back was to around 200kb {20-25KB/s} so most users do not notice it)

        if you are an VM user do note

        they have Set the limits so they are download cap trigger takes aprox 15-20 mins to happen if your downloading at Full speed (not 50mb),

        if your Uploading data at Full speed for aprox 30mins (it may be 1hr or longer now as they put the upload cap not far off the download cap limits guess they did this for legit P2P TV apps) that will also set the second trigger off unless the first one has all ready happened, if upload or download cap has been hit it affects Both upload and download speed for 5hrs from when it happened and can only ever be triggered once as it lasts for 5hrs (it can be twice if you did the morning trigger as well but that takes 2x longer to hit them caps aprox 30mins down @ Full rate)

        (50mb not sure what happens to download speed, they better make sure it only affects the upload speed)

        still there is no monthly cap on virgin services just daily limits that lower the speed (still think 75% is a lot thought on 10mb it is any way still you can still keep on downloading about 50gb an day even with that limit in place)

        -----

        bt be funny if they do an 100gb cap on an 24-100mb service (when they say its unlimited again when its not)

        BT Inifinity will be usable for Most of the UK as its FTTC (cab) not FTTD (Door or House) once its rolled out in your area's (1-5 years) if your Exchange is enabled for 21CN more likely to get it sooner then later (as the cables and fibre has been upgraded at that Exchange to support FTTC later on, as 21cn makes bugger all dif for ADSL1 or 2 users, FTTC is what its used for)

        fibre to the cabs (or DP) in this case that's norm Only between 100yards (40-100mb users VDSL) or less then 500 yards away (up to 24mb ADSL2 tech avg most likely 15-20mb) from you all them poles goto an Point that norm Close to the streets they all merge up to that then goto the main Exchange the Fiber box going to be fitted next to the DP box where your ADSL or VDSL will be servied form if you take BT inifinity

          Existing traffic management

          leexgx, Not quite sure about the point you were making with your post. It seemed to be that you supported the current traffic management system at Virgin, where your speed is capped temporarily if you download a certain amount at peaks times. I completely agree the system was fair and did not discriminate against anyone. You download a certain amount of data during peak times your speed is cut for 5 hours. Great, nice and transparent.

          They then extend the peak time to be during the day as well, which I did not support. But this is one step too far. Now Virgin instead of offering a dumb pipe now discriminates against certain traffic. And most people on the forum are falling for the spin of, well this traffics is used for illegal reason's, or it uses a lot of our networks capacity. That's bull.

          What is really happening is that Virgin's network is not fit for purpose and they don't want to upgrade it, so instead they put in even more restrictions (these new restrictions now last till midnight instead of 9pm).

          Not that these restrictions will have much effect as freetards now get movies, etc from file sharing sites like rapidshare etc. So the network will still be slow.

          Do I use P2P or newsgroups, not really, so it does not affect me. So why am I angry, because if it is P2P and Usenet now what will it be next? Virgin have already stated they want to give priority to people watching streaming TV. So Virgin and other ISP's get to decide what you are going to do with internet connection. This is different to the current system that cuts your speed no matter what data you used to hit the limit, P2P or TV or Skype.

    Madness

    A GB is a GB, and network congestion is network congestion, whether it's ftp, P2P, http, smtp, or crap.

    If some freeloader is downloading 10 TB of this week's US TV output by http or nntp or ftp it causes just as much congestion as if they had been downloading it by some P2P protocol.

    OK there are some time sensitive protocols that you might want prioritised but you do that by prioritising those specific protocols not by throttling P2P.

    Bring back pay per GB.

    1. Anonymous Coward
      Anonymous Coward

      The idea of P2P?

      Isn't one of the tenets of P2P sharing that you'll get bits of data from potentially anywhere, multiple sources, and will also be sharing those back out yourself whilst doing it? It's not meant to speed downloads up, but to spread loads around in a distributed manner.

      So since you're expecting to wait a period of time for it to complete anyway (and reliant on others having completed files to seed in order to get it all eventually anyway!), it seems to me if something's gotta give it's the obvious candidate for throttling.

    2. CD001

      Ummm... what?

      If you read the article you might notice that this seems to be a shift of focus onto the upstream.

      They're increasing the upload speeds available to everyone so you can get your home videos on YouTube that little bit quicker. However, and this is the important bit, they've not said anything about illegal filesharing over P2P - merely that they're restricting the bandwidth it can consume. Could this possibly be to do with the nature of P2P, in that it uses the upstream to seed YOUR torrents?

      So ye-es, pulling down 10TB over HTTP is the same as pulling down 10TB over P2P ... except with HTTP it's a web server sending the data down (via a professional backbone connection you'd hope), with P2P it's some other twonk(s) chewing through their upstream bandwidth (on their home connection) to seed the damned thing.

      At least, that's how I read it - it doesn't appear to be about copyright infringement (which is what everyone assumes as soon as the phrase P2P appears) it's about freeing up the upstream (good for gamers).

      The question is - when do we expect they'll announce Virgin VOIP? They've got to be targeting that upstream bandwidth for something.

    3. The Indomitable Gall

      The point of net non-neutrality...

      The academic justification behind a non-neutral net is that certain applications require extremely low lag (eg streaming media, VoIP) and certain applications don't (eg bulk file downloads). The ISPs are only doing what the universities have been proposing since the 90s.

      I agree it's madness

      When the network starts getting congested, share the bandwidth between the users, independant of what they are doing. If I have paid the same as someone else, why can't I download Suse 11.3, but the kid next door can spend the whole evening streaming (illegal) TV programs, or surfing YouTube.

      It can't be hard to do; the network already knows how much congestion there is, and there are already systems in place to limit user's bandwidth (normally just dependant on tariff). I can see that this idea will fail; p2p will change their packet type to avoid the restrictions, the restrictions will change, it will just become a race.

      Just imagine the uproar if the local council said that instead of sharing out the council bills among everyone, they said that Conservative voters can pay all the bills, and Labour voters don't have to.

      Moving

      You can port your number from Cable to any other Telco..

      You can also port numbers from any mobile operator to another.

      Not sure why you think this isnt the case?...

      Moving from BT to Tiscal = Install charges, possibly new modem, and transfer of phone number

      Moving from Virgin to BT = Install charges, def new modem, and transfer of phone number

      Your argument is that VM isnt having to share their network with other operators.

      If you would even try to paritally understand the differences between HFCN's and DSL configurations you would see that for "Cable" to share would mean that any operator on the line would change the performance of everyone else on that line. So if O2 had users that were pegging the line 100% of the time 24-7 then other users could suffer.. Then the only isp's that would be "picked" would be the ones who had no traffic limits, thus screwing over everyone else.

      Do a little bit of research and thinking before you just jump in and start crying fowl..

      If they are refusing to port your number then you have an argument, otherwise.. FAIL.

        You ARE stuffed if you're on cable AND want to stay on cable... although that is changing (very) slowly as BT roll out the fibre.

        I've been on cable since it was Telewest; it's a better technology than ADSL so I'd be loathe to switch to another provider because doing so would mean that I lose cable, so yes, I am forced to use VM IF I WANT A CABLE SERVICE - which is what, I think, the OP was trying to say.

I live down in the South West so to be fair any kind of throttling will just bring it in line with that of other providers in the area, another point would be that the true bottle neck is that of the peers in the swarm, I have only seen close to 10mb in the past and that was off a fast server no doubt...

    So how will this affect all the users with Secure FTP's and VPN TUNNELS?

    I was sure they rolled this out ages ago. My transmission speed through a VPN varies greatly depending on what time I connect.

    As for torrent.... that is so 90's and well past its use by date. Nice to see no Virgin customers ended up on ACS:LAW's list so they can't be all bad. SKY/PLUSNet I wouldn't be jumping ship to them if you want good download speeds. Could be a poison chalice

  19. Neill Mitchell

    Depends on how the do it

    If they actually throttle the speed then it's not so bad. However, if they continue to achieve their "throttling" as they currently do, namely by massively increasing the packet latency, then this will be a disaster. The time I triggered the "throttling" (after downloading a Linux distro I hasten to add) my link was totally unusable until it lifted due to the massive packet latency they'd applied. 75% speed cut my arse.

    As someone else said, it's nice to hear this via a news website rather than Virgin themselves. They are very bad at publicising their usage policy. It's not mentioned when you sign up. I only got directed to their policy web page after phoning them up about it.

    Good news about the upload speed increase though. All providers rely on Joe Public ignorance about MBit/sec versus MByte/sec. 512MBit or 64MByte/sec theoretical upload is actually pretty crap when uploading home movies etc.

        No need for MITM

        They don't even need to do a MITM attack. With torrents, any IP address in the world could be a peer, so you'd have to throttle the protocol and hope they don't use encryption. With Usenet, there is only a limited number of servers worth downloading from. So if I'm connected to ssl-eu.astraweb.com, VirginMedia can be pretty certain of what type of traffic that is, even though it's encrypted.

    If you actually *use* your connection at its headline rate for 10 (ten) minutes, you get throttled down to 25% for the next 5 hours.

      why as your upload is going from 1.5mb (that i am on now) to 5mb even with 65% cut back after you have done 6GB of upload would only be droping to 1.75mb for that short time that in no way would affect download speed unless you was trying to send more 1mb/s (100KB/s) of data when trying to download at full speed (need about 60KB/s upload for overhead when downloading at 50mb {5MB/s})

      personally less users who use 50MB better for me as my service will be better (lower ping more stable connection, but i am in an none congested area so none issue for me any way)

      set utorrent set to 50KB when downloading {10-20MB users set it to 11KB when downloading} (download should not be affected that still run at 50mb {that info Needs checking thought as it does not state if the download is also affected })

      "I pay for access to the internet at a specific speed. I do not pay for a tiered level of access that is decided by someone else when they feel like it."

      Actually this is a pretty clear indication that you do, indeed, pay for a tiered level of access that is decided by someone else when they feel like it. Since this is a capitalist economy, you are free to vote with your feet and move to another provider, who also provides a tiered level of access decided by them when they feel like it.

      If you don't like it, you are also free to start up your own ISP providing truly unfettered humungo bandwidth to the UK consumer with no restrictions whatever. :)

      Only downside is that you will also have to abide by all the laws governing ISPs including (but not limited to) keeping all the emails that ever traverse your network in an easily accessible archive, allowing officials to install whatever monitoring kit they feel like so they can be a man in the middle when investigating "crime", providing remote and on-site access to said officials at whatever time they feel like turning up so they can investigate said "crime", and all the other niceties of providing a service that get abused by "criminals" (definition yet to be properly defined) every second of every day.

      You may also end up liable for any infractions by your end users that were facilitated by your product. They keep changing their mind about whether ISPs are liable for facilitating illegal downloading, spam and other "enabled" crimes seemingly on a weekly basis.

      So if you do start up your own ISP providing proper 1:1 contention symmetric fibre-based connections of the >100Mb/s truly unlimited and no throttling ever variety, I'll take one of your top package please, my current DSL is limited by the legal obligations of my ISP and it's harming my ability to download... linux distro's :)

        It is not Virgin's legal obligation to throttle its customers bandwidth for downloading over an arbatery amount over a period of time. In fact I would think that it is the oposite, it is their legal obligation to provide the service that was advertised at the time the contract was entered into.

      Well, a 1hr HD show on BBC iPlayer is roughly 1.15GB.

      If you're downloading/streaming video (iPlayer, 4oD, demandfive, lovefilm, etc), you need a high download limit. However, none of these services require a download speed of over 2Mbit/s, so even a throttled connection is usually fast enough.

        Not to mention the fact that if you're with VM anyway you can pull iPlayer and 4OD down directly through the set-top box and watch it on your TV anyway - odds are that if you're going to pull down an hour's worth of iPlayer, you're not going to be doing it on your PC ... well, unless maybe it's a laptop and you're in bed.

    About time...

    A while ago my Virgin internet connection became unusable due to high upstream utilisation. I live in a student area, and they were buying the uncapped 50mbit service and torrenting 24/7.

    It was partly Virgin's fault for overselling the network, but also the fault of those who were behaving like gluttons selfishly gobbling up all the food in an all-you-can-eat buffet, leaving crumbs for everyone else. My connection was eventually fixed, and has been fine since.

    Though I'm not glad to see this P2P throttling being introduced, I can appreciate why Virgin have decided to do it, given my past experience.

    get it right will you

    Virgin have increased the upload speed that many users have been asking for.

    They have also looked at the useage of the traffic on their system and have concluded that the vast majority of their users would get a much better service if they restrict the bandwidth used by P2Pers and Newsgroupies during peak times.

    This means that the vast majority of their subscribers will get the service they are paying for and the freeloaders will have to accept that they must change their downloading habits or try to find another supplier who will provide the speeds they are used to and don't shape traffic etc. (Good luck with that).

    Get over it, you have had it too easy for too long already downloading illegal stuff at the expence of my internet usage.

    I'm sure i saw a little while back that P2P etc was using the majority of all traffic on the net.

    Just set your downloads to overnight and use the net for live streams etc etc or go away and leave me with more bandwidth that I can use.

    Slingbox

    I have to (due to living in a restricted building area) use a Slingbox streaming (VM upline) Sky+ to my flat (on BT down-line) on the other side of London, so initially I am happy that my up speed will increase from 700K to 2MB!

    I wonder how VM see the data coming from my SlingBox, I doubt its P2P, more lilely HTTP (encrypted) but the upload caps might now work out to be a little awkward. I have worked out the SlingBox would only broadcast for 30ish minutes before reaching the 3gig cap (at 2mbs). If I understand this correctly does that mean that the 75% cap would then reduce my upstream to 500kb after this until (between for example 3.30 - 8pm?)....

    I might have to upgrade to the 50mbit line PURELY for the upload speed to keep a watchable connection when the 65% cap is put in place!!

    Anyone else using a SlingBox with VM?

      still want to know if there is an download limiter in play but i guessing VM would not do that on the XXL service (the link does have N/A on it so i assume its upload lowering only)

      and also this title is Very miss leading from the register as well as its NOT P2P throttling if it was there be No daly cap it be like Tiscali and there lame 4KB/s bit torrent speeds at peak times (something like 1pm to midnight lol)

    The issue with P2P

    Broadly speaking, network components share network resources amongst users on a per TCP connection basis. UDP transfers are typically expected to be brief (e.g. DNS queries) and therefore, insignificant. This works fine with traditional applications like http and ftp, where a single TCP connection or a few TCP connections are used per application. However, P2P applications effectively "cheat the system" by establishing large numbers of distinct TCP connections with multiple destinations. Many P2P applications also use UDP, again using multiple "connections" with multiple destinations. The end effect is that P2P applications grab way more than their fair share of available network resources, resulting in poor performance of other non-P2P applications and complaints from the affected users.

    VPNs or applications using nntp, ssl or ssh on single TCP connections are limited by the normal mechanisms, won't grab unreasonable chunks of available resources and are therefore, unlikely to attract attention for reasons of bandwidth usage.

      STM and Shaping are different things

      I don't think you are understanding the difference between STM and Shaping.

      For NNTP and P2P these types of traffic will be shaped, regardless of how much you download/upload based on the total load on VMs network.

      I think I read NNTP and P2P will be restricted to a MAX of 20% of the network traffic.

      So yes, usenet users will be affected by this.

    No guarantee of upload speeds shown

    I've called Virgin Media customer service on many an occasion as my upload speed hovered around the 0.01Mbps mark (when I had the 10Mbps service and then the 20Mbps service), in the end the solution turned out to be getting 50Mbps!!! No other option as I couldn't get out of the 12 month contract, apparently even if I could prove the broadband was faulty the TV and Phone worked fine so I'd have to buy out of those services.

    On many of my calls the agents insisted that they couldn't do anything about upload speed as it's dependant upon the site you're uploading to. They wouldn't guarantee upload speeds, so goof luck if you switch to Virgin hoping for a good upload speed!

    Contention

    I invite everyone to remember that you're paying for a consumer grade service with a contention ratio of (at least) 20:1 or 50:1. While all ISPs try to give people something that looks like the service they're paying for, they've never been under any obligation to actually deliver it 24/7.

    Offcom's investigations into broadband speed have always been to do with actual achievable speed and not usage.

    So you might have a 50mbit, or 8mbit service, but unlimited has never been unlimited. Their actual obligation to you is to provide 1/20th or 1/50th the service you signed up for. This has always been the case.

    Traffic shaping and AUPs are just an attempt to spread the pain more evenly over their entire network, otherwise some shit down the road from me who's a US tv/every other linux distro/super pirate who tries to max out his connection 24/7 is going to cause me and the other 18+ people on the same line to have some serious issues. Screw him is what I say.

    Overall most people get waaaay better than that minimum. Anyone who thinks that for their £20 - £60 / month they ought to be getting an uncontended, unlimited service please go to your doctor and ask for some anti-delusion pills.

    so stop bitching they have now Given you 1mb upload for 10mb and 20mb services (was 256kb and 756kb upload before and an massive 5mb upload on the 50mb DW thats Faster then Most ADSL connections Download speed that i ever see when i service PCs) that will benefit more then 10mb users as the connection was buggered due to the limited upload speed you got when Traffic Management came into play on the upload speed

    and on top of that they have 2x the upload cap on the day limit before it was quite low and would only take 20-30 mins to take affect (setting off the upload trigger sets the download limit as well or vis versa)

    id say 98% is not legit traffic for the heavy downloaders :) 90% seem not very realistic to me

    Only they seem to have shown way more teeth than Ofcom on this.

    Just use Be broadband... especially if you are on an LLU exchange. 2mbit upstream, practically no download cap (They have a Very Fair Use Policy), no traffic shaping whatsoever. Just a good old fashioned network connection. Use Andrews and Arnold if you want ipv6 and no shaping, but they charge an arm and a leg for download allowance...

      Nor do they seem to want to run a traffic snooping system using Chines hardware like some of their competitors.

    Whoop!

    Yey! 2MB/s upload on my 20MB/s connection? Sweet! About time too! Better to me working from home sending emails and using Skype video conference and VOIP.

    Bandwidth hogging P2P users to be throttled and most likely to leave to another network? There's no bad here. Let them go. Just means lower peer-contention for those that stay. Win, win.

    Freetards are not thieves

    To AC above.

    We stopped calling freetards thieves because they aren't thieves. I recommend you learn some law and in particular, I point you at the Theft Act 1968 which says, in S1(1):-

    A person shall be guilty of theft if he dishonestly appropriates property belonging to another with the intention of permanently depriving the other of it.

    Since copying intellectual property does not normally deprive the other of it, it is not theft.

    So there.

    Rapidshare etc FTW

    Since the new restrictions solely apply to uploads (at least for XXL users like me), the use of file sharing sites like Rapidshare will not be affected.

    Although download managers like jdownloader are not as pleasant to use as decent bittorrent clients like Transmission (my personal choice) they are a perfectly reasonable alternative.

    They never stop me, mwah ha ha...

    PS Virgin don't give a crap about illegal filesharing, they just don't want to invest to enable heavy users to get what they pay for. This is nothing to do with piracy and everything to do with load management.

    heard it all before

    had BT out in Surrey and was throttled back most evenings to the point of not even being able to browse for an "unlimited" connection apparently 300-400GBper month was excessive, to some maybe but I beg to differ.

    Throttle USENET also though?? dont virgin provide USENET hosting of Warez? I know that wont account to real network traffic as its "internal", but P2P is a major bw hog.

    Now in London and on a 19Mbps service with NO FUP nor throttling of any kind...

    and I was very dubious of getting Sky

    just the one question remains -if I am on the some recent released list ;)

    RIP BBC and Sky Players then

    I may not have got the term right, cos' I have never used them and have no intention of using them; but they are effectively dying.

    Why does nobody ever mention....

    Ummm, why don't the ISPs cough up, pay for infrastructure and then give everyone QoS over their pipes and make sure that every person has an "even" tube. That way, they can only use bandwidth given to them.

    Oh, sorry. That way ISPs still get away with selling connections well above the capacity of their networks whilst still advertising whopping speeds. And then when their infrastructure groans under the weight at peak times, because all of the iphone users out there are using youtube they can conveniently blame it on the filesharers and P2P users and their heinous, subversive and illegal practises. All Traffic Equal in equal tubes. Just saying.

    Chatty

    All those of you rabitting on about bandwidth (even the ones of you using the term incorrectly) are missing the point by a country mile. There is more to network performance than bandwidth usage. To stay away from technical terms P2P conversations are very chatty and therefore keep the network hardware busy. A router or switch dealing with a lot of P2P traffic will tend to have a high processor usage. A network dealing with lots of P2P users will suffer performance problems because it's routers and/or switches will be working too hard.

    I can give you a parallel if you like. Imagine a premise LAN made up of old switches that don't support spanning tree. Now imaging somebody creates a loop on that network. We've all seen what happens next, in next to no time the LAN is brought to it's knees by a broadcast storm. Everything is maxed out by relaying broadcasts that are coming in through the looped ports. Imagine that upstream of this there is a multilayer switch on the other end of a fibre link to head office. The layer 2 network stops at the port on this switch, beyond there it's layer 3. Somehow, however, everything else connected to this switch starts having problems. This shouldn't happen, those layer 2 broadcasts should stop at that port and go no further. So what's the problem? Check out the switch's CPU utilization. It's huge because the switch is having to look at each of those broadcasts and make a decision on each one. Broadcasts coming in as fast as a 100Mb EES circuit can carry them are using up all the switch's decision making capacity. Until you switch on some sort of broadcast storm control you're stuffed. Limit broadcast storms to, say, 10% and suddenly everything is back to normal.

    P2P traffic is a lot like those broadcasts. From a network hardware POV chatty applications are a pain in the arse. This is why ISPs don't like P2P. As home broadband speeds get faster so P2P can put more load on the network hardware. So more and more ISPs who are increasing the speed available to subscribers will start to restrict P2P traffic.

    A lot of people think that P2P is really clever coding. Most network engineers will tell you it's shite coding because it is done with no consideration of how networks actually work.
