to help more folks use their paid-for adsl service in any way they feel like - the local dc++ hub would appear to be at ibust.kicks-ass.net

You are wrong there. Say you rent a line out to users and the capacity of the line is x. Shortly after reaching your 5:1 ration, all 5 users start to download at maximum, reducing the quality of service. You upgrade the line at your own cost, but its still not enough because the users continue to push the limits. What do you do? Surely you can't tell me that the abuse on your line from your subscribers is not going to impact you?munwaal said:Abuse is relative - local traffic (as pointed out by SpamTheMan) costs telkom absolutely NOTHING, either in traffic costs or maintenance costs.
And likewise it's up to each of us to be fair to the infrastructure (service offered) i.e. not to try and suck the network dry.MaD said:At the end of the day one can only hope for them to be fair and improve the pricing structure so as to have everyone not feel like they've been had.
Silent_Bob said:lol...... i wouldnt mind if adsl got capped at like 50 gigs then if local is also capped. the crux of the matter is telkom is happy to give us a MERE 3gb and once that is used it is **** YOU. they keep comparing us to international isp's etc, but no other company worlwide offers a (according to telkom) HUGE cap of 3gb, TO SUITE EVERYONES NEEDS. Telkom couldnt care about any of us, i guesss we just get used to it, the goverment will realize one day that they are killing all the decent people of there money and is holding the country back. WELCOME TO OUR LOVELY COUNTRY: SOUTH AFRICA.
PLEASE TRY KILL ANYONE WITH MONEY AND WASTE HUGE AMOUNTS OF MONEY ON DIEING PEOPLE.
That is Mbeki for you.
End of story: **** THE WHITE MAN
This is hysterical! Another post which has been hijacked and for some obscure reason (yes, it is obscure because somebody read their own prejudice into a vague statement), has been turned into a race row.killadoob said:tibby dude you lost the plot
what does being white have to do with high adsl prices
do black ppl get it cheaper?
With talk about capped accounts being restricted for local access as well, I wonder what has brought this on.
I saw on a forum a couple of days ago, somebody hinted that there are home users downloading 100GB per month. Surely that kind of usage warrants a leased line rather than ADSL? 100GB must be classified as abuse for a home any home user, running maximum upstream and downstream for 24x7. And yes, there is an impact on network resources, despite what some people may think. I must say, that these few who do this kind of thing may have hurt the others who keep their usage within reasonable limits, albeit high.
An analogy could be drawn along similar lines to the Cape water crisis of recent months.

You do not seem to grasp the way our internal (South African) telecoms network functions. By 2001 Telkom had succesfully rolled out their nationwide ATM network. This network spans the entire country (more or less) and is the backbone of our telecoms infrastructure. The reason Telkom implemented this technology was to carry their existing voice and data transmissions and to allow for later expansion. Each local Telkom exchange is connected to this network. If your exchange allows ADSL lines it is because there is a DSLAM connected to the ATM network present at that exchange.
Now Telkom already had enough reason to install an ATM network and the maintenance of that network is a fixed cost (which I do not know). That cost is unaffected by the volume of traffic passing passing through the network. The ATM network runs on Fiber Channel hence it does not suffer from wear and tear due to usage. A single ATM link, 135 Mbit/s, is capable of carrying 270 simultaneous 512 Kbit/s ADSL connections. Given that Telkom charges R599 line rental per 512 Kbit/s ADSL line they would be making around R 161 730 a month, and given that fiber optical cable is relative cheap (approximately $0.30 per yard = R 2300/km) it would make sound financial sense to expand the capacity of any exchange that did serve that many customers.
So traffic on Telkom's own network essentially pays for itself (just in terms of line rental, let alone the savings made by not having to send traffic over the SAT3 cable), but what about local peering with other ISP's? Well local peering is normally an agreement between two parties who have a great deal of traffic flowing between each others networks. An example would be SAIX peering with IS or UUNET. A peering agreement is basically this, both parties agree to split the costs of the line linking them and they typically agree to expand that line dependant on traffic. Now let's use IS and SAIX as an example. The two agree to set up a peering link and put a line in between the two ISPs. A Telkom line. Which costs SAIX virtually nothing given that that line will simply be a virtual circuit on the ATM network. Telkom will then assign a monetary value to that virtual circuit and expect IS to pay half that cost. So local peering costs Telkom virtually nothing either.
Your analogy was false in that local bandwidth is not a commodity that can just run out. It's not like there is a limited amount of fiber available in the world, if a link becomes saturated then it is already making enough money to pay for an upgrade.
I hope you've learnt a bit reading this, if you'd like to learn more about Telkom's ATM network give some of this a read. People who are using the maximum amount of bandwidth possible locally are in no way affecting your connection. If we where talking about international bandwidth then you would probably have a point, but since Telkom have already prevented any issue with people unfairly monopolizing international bandwidth by implementing the cap, you don't.

noone said:Oh and btw, seems everyone here fails to grasp the idea of a contention ratio and STILL applies linear maths to everything. Shame. You can run close to 4000 users (uncapped I might add) all on a 1meg connection and use barely 70meg of bandwidth if the contention ratios are correct.
By the way you're thinking, 4000 users will use 4000 meg or something.
