Okay, so to state the obvious for those who missed the point... The congestion will either be directly in front of user because they're flooding their uplink or towards the destination (beit a single central network or a set of storage clusters housed at, say, 6 different locations off 3 different providers.) It is very hard, in my experience, for something like this to congest the general network. The congestion occurs where either bandwidth drops off--such as with the edge dialup, DSL, or cable modem link--or traffic concentrates. Just like someone broadcasting a concert. Either you as a user can't receive the feed because your pipe isn't big enough for the stream or the network/servers sourcing the traffic get bogged down and, generally, the rest of the folks out there not watching the feed don't know there's a problem. If you're not participating in that traffic, the likelihood that you'll be impacted by it drops off dramatically. Yes, the PTP model will behave a little differently but in that case, you're more likely to see individual users having issues (either hosts or clients) rather than everyone as a whole and it *still* won't impact the broader network. The more central clusters you add, the more the traffic pattern will start to behave like the PTP scenario and the lower the probabilty of broad impact. My point was simply that if you think it through, there really isn't any reason to be concerned about it.

What would be obscene about that is from a design POV it would be a waste of resources. Music and TVcontent are from a small number of sources, and there are a massive potential number of users. What should happen is instead of transmitting large video files... block checksums should be transmitted, and only files that are completely foreign should be transferred. Whereas everything else being backed up is just an assignment of account access to existing blocks that would already have been stored on the content servers. And then also, a user storing 10GB of music would probably take only a few megabytes of their account space, once the space used is evenly divided by the number of users that have that block saved, since a majority of music files backed up would be file-identical with material someone else had already backed up, and identical to material already in the iTunes store (which they could pre-seed their database with). -- -JH

Re: iCloud - Is it going to hurt access providers?
If you're worried about the problem of tens of thousands of users simultaneously trying to upload files to a central point then I'm not the slightest bit concerned about the network as a whole. In this circumstance, one of two things will happen and possibly both, depending: either a) the users will screw themselves by flooding their uplinks in which case they will know what they've done to themselves and will largely accept the problems for the durration or b) (and far more likely) the links apple is using will become flooded or the systems overloaded in some way or another in which case the customers will say, MAN, this *SUCKS* and likely whine at apple. Because the nature of the traffic isn't much different than, say, a windows patch release, the traffic won't be *all of a sudden* but will be spread out over hours and days. The probability of it causing disruptions anywhere but at the immediate source or within the near vicinity of the desination is low, as I see it. IMO, the only ones who really need be concerned are Apple's bandwidth prodivers because traffic will be concentrating within their networks and especially in the nodes apple connects to. -Wayne On Sat, Sep 03, 2011 at 11:20:13AM +, Skeeve Stevens wrote: Hey all, I've been thinking about the impact that iCloud (by Apple) will have on the Internet.

I've not bothered to look too deeply at dns and packet traces myself. I'm guessing that all these things are going to hurt the DSL providers more than the docsis/fttx/pon based providers. Those folks have broader capabilities by pushing updated configs to the devices. The DSL based providers are more limited in my experience and likely to see a poorer ratio of up:down. SDSL was just not common enough, so most A/VDSL based providers have something like 15:1.5 whereas comcast (for example) has 22:5. I've seen the 22:5 service burst (or should that be buffer/manage the queue) to around 80Mb/s down in some cases.

From what I can see there are some key issues: * Users with plans that count upload and download together. * The speed of Asymmetric tail technology such as DSL * The design of access provider backhaul (from DSLAM to core) metrics * The design of some transit metrics So basically the potential issue is that a large residential provider could have thousands of users connect to iCloud, their connections slowed because of uploading data, burning their included bandwidth caps, slowing down the backhaul segment of the network, and as residential providers are mostly download, some purchase transit from their upstreams in an symmetric fashion. In my opinion. Home networking (including personal clouds) have to change the brain damaged model of asymmetric tail technologies. Giving back the original peer-to-peer nature of networking the asymmetricity of the access technologies will not be tolerable in such a level (1:10) we have today. Maybe 1:2 should be more acceptable. You don't have to worry bout this changes, but access provider cannot claim any longer 100MBps (while upload speed ~10 Mbps), but probably 60-70 Mbps (with upload ~ 30 Mbps) They have to retune access services.

Re: iCloud - Is it going to hurt access providers?
I'm not 100% certain and have no references to back it up but I recall reading an article which described the Apple cloud music strategy as being one where for existing identified music it merely stores a reference of some kind against your account rather than actually storing an additional copy. Presumably for the sake of sanity it would be implemented in the application where it saves the end user the cost/time of uploading as well, if for no other reason that said cost/time/cpu resource would also be a real cost to Apple directly or indirectly. Mumble-something about even for your own music you have ripped-not-purchased, pay $nominal-annual-fee and it magically becomes a legal licensed object (which obviously they did because then it becomes something they have one single stored copy of with references on remote accounts).

What would be obscene about that is from a design POV it would be a waste of resources. Music and TVcontent are from a small number of sources, and there are a massive potential number of users. What should happen is instead of transmitting large video files... block checksums should be transmitted, and only files that are completely foreign should be transferred. Whereas everything else being backed up is just an assignment of account access to existing blocks that would already have been stored on the content servers. And then also, a user storing 10GB of music would probably take only a few megabytes of their account space, once the space used is evenly divided by the number of users that have that block saved, since a majority of music files backed up would be file-identical with material someone else had already backed up, and identical to material already in the iTunes store (which they could pre-seed their database with). -- -JH -- two eyes to tease, an aargh ... an oh there's a pie in there somewhere
RE: iCloud - Is it going to hurt access providers?
The copper technologies of DOCSIS and xDSL are well established in residential deployments and they are asymmetric by design. I don't think near-symmetric speeds are on the CableLab's and Broadband Forum's short list of future features. Even GPON is 1:4. As more fiber is deployed, I believe deployments will eventually migrate to some variation of EPON where symmetricity is built into the design. In the meantime it is what it is. Somewhat tangential, has anyone graphed out the upstream/downstream ratios of the various technologies (various generations of dial-up, DSL, fiber, etc)?

That's as may be... but the real question, I think, is this: What's the asymmetry of the *intermediate* networks? It wouldn't make sense for cablemodem providers to provision symmetric transport inside their MANs if they didn't have to... so if they *don't* have to, how hard can the push it with the way they're provisioned now? Or is the transport natively symmetric, as I suspect, and they're just letting it all sit there on the return side. Must gall their sisters... :-) Cheers, -- jra -- Jay R.
