| I wish higher upstream would be offered A friend of mine's friend pays $2000/month for a symmetrical 20mbit/sec line burstable to 45 with Cox business fiber.
I've got another friend who has a full 1.5mbit/sec T1 line via xo.net, which I believe he pays around $400/month for. I've read all these claims of how fast cable and DSL can go, yet as far as I know, not a single North American ISP offering cable or DSL gives users a shot at seeing what their line can do, especially in the upstream direction! Someone please correct me if I'm wrong, but to my knowledge the only cable provider that'll give consumers a taste of upstream potential is cablevision, with choices of either 2 or 5mbps speeds. Everyone else? Well you're lucky if providers in non-FIOS areas give you a top speed of 1mbps. In my case for example I have the fastest consumer internet I can get at 10mbps/1mbps. Why is it then, that ifI want to get 2mbps upstream, which cable can do BTW, I have to pay 5 times the price for double the speed upstream, as I can only get it on a business package?
Why is it that every single provider of cable/dsl services is afraid to even offer consumers greater upload? True not everyone will use it, but there are those that want it, and they shouldn't be excluded. Tiers of internet access should be offered from the lite user to the power user that wants upload abilities. I mean the internet is a computer network after all, and sending data should be no different than receiving it! Are the internet peering points metered lines, hence the reason every residential ISP won't even consider giving more upstream options? It's like they're even afraid to offer symmetrical speeds like 1.5/1.5 which cable could do! Why is this? What exactly is the difference between the internet I receive and the internet my friends that pay through the roof for their 1.5 and 20 meg lines get? | |

2 edits | The answer to your question... said by kd6cae:Why is this? What exactly is the difference between the internet I receive and the internet my friends that pay through the roof for their 1.5 and 20 meg lines get? The internet you get has: No SLA (ie no guaranteed uptime), may have a transfer limit (ie cap), has a lower priority of packets (versus a business line), is much more oversold, etc.
As for upstream - it's the way cable and DSL are designed:
For DSL, the best obtainable upstream speed is commonly around 1mbit or less (up to 1.5 max). This is because the "noise" of the tons of circuits going in/out of the CO interfere with the signal - now on your end you don't have 50,000 pairs running to your house so it's a moot point.
And for cable, each node commonly has 38mbit down but only about 8mbps up - shared between all users. DOCSIS 2.0 allows up to 30mbps upstream, however I am unaware of any cable providers that actually configure their systems for that.
WHAT IT REALLY COMES DOWN TO:
Downstream bandwidth is used only by user request. Most people have a practical limit to how much they can download (ie hard drive space). Meanwhile upstream bandwidth has no such limits - as is the case with P2P applications some will eat your full upstream 24/7/365 if you let them. Now imagine your cable company decides to completely uncap the lines - and two of your neighbors decide to host their favorite pr0n on bittorrent - bam your 8mbit of communal upload is saturated and everyone's experience is reminiscant of the dialup days. Sure they could advertise the service as 40/10 - but I think you'd be a little upset with their "oversell" ratio.
EDIT - Your tag line says it all: "P2P shouldn't be a crime" --- Which I agree with as long as you're not on my node

| Also, there *is* a post-GPON plan (yes, at Verizon). In addition to the BPON-to-GPON upgrade (which *will* happen VZ-wide) there are, at minimum, two more upgrades in later stages: 10GPON (factor 10 GPON) and WDM PON (VZ has also left open a possible direct migration from GPON to WDM PON, skipping 10GPON altogether). The real issue that is being discovered with the Internet, however (and it's something that VZ as a company can do little to nothing about, as it can only control part of the issue) is *out-of-network bottlenecking* (due to bandwidth constraints, QoS constraints, or a combination of the two). This is something that *I* have run into since I first got Comcast HSI, and by and large, this sort of bottleneck would *not* go away simply by switching to FIOS because the bottleneck is outside the control of either Comcast, VZ, or their respective bandwidth providers. Until this can be addressed, even GPON is adequate for non-business bandwidth needs. | |
