Wrong Dude. Here is how it works :
WBS pay for :
Local Access circuits to UUNET
Port Charge
Local Peering access
International Bandwidth
By default, up till recently, the ISPs peered with each other with no charges incurred, other than sharing the cost of the leased circuits. This peering agreement basically forms the network that is the SA Internet - and costs here are low for the ISPs. Telkom are trying to change this at the moment - check out what they are doing to IS - they are trying to get them to pay a fee for the peering link.
The port charge covers the infrastructure charge for the ISP (Router, local circuits etc etc).
International Bandwidth is charged as per needs basis, depending on what you are after. You have a couple of choices :
Carrier technology (Whether you want your international bandwidth to go via fibre or satellite or a combination of the two).
The CIR (Committed information Rate) that you require for international browsing.
The multiplexing ratio on that CIR.
To unpack this a bit. Say you want a 1mbs service. You install a 1mbs leased circuit to your ISP. You then decide that you want 256kbs provisioned for international traffic. (CIR). You will then have to decide what sort of response you are after, and buy international bandwidth accordingly. Obviosly, the closer you get to a 1:1 multiplex ratio on fibre the more expensive it gets. There are also some other options available nowadays like MPLS that have varying degrees of guarantees, and you pay accordingly.
My GUESS is that WBS are doing what most corporates do : monitor what volume of traffic is going internationally, and buy a CIR accordingly. international traffic is expensive, so that is why they shape - to get the best utilisation of what they already have. They have also had a look at what sort of response times their competition give, and have decided on fibre. As far as multiplexing is concerned, again a guess, but i would put it on a 1:1 contract if i was shaping - you want to run the service as close to 100% as you can and you cant do that if you are sharing the line with another ISP - your own QOS will go for a ball.
By the way, i have proposals from UUNET, IS and TELKOMSA sitting on my desk and they are ALL more or less the same wrt the service they offer (fibre, sat, multiplexing ratios etc etc).
Debate closed?

I hate it when a thread is closed
Although it is still assuming that WBS did buy that bandwidth in that manner lol

Added: BTW I have been assuming for some time now that WBS do not have a leased line type whatsit to carry our traffic from WBS to UUNET SA. My assumption is that they have equipment installed at the UUNET SA operations centres in Jhb & CT (the reason why Luis is always at UUNET SA when there is a network problem - WBS equipment is mostly there?).

Or to argue for a bigger pipe
when their current pipe is at capacityIn one of my conversations with Shaun it was mentioned at one stage they had a 53Mb pipe in use . Dunno how true that is now
could very well be that they are connecting for rf technology. not too sure.... you only have to use telkom if you are passing public property or if you dont have a rf license. wbs have a license, so it would save them big $$$ to go rf... it still doesnt detract from the fact that they have to buy int bandwidth though...

I was just thinking that WBS probably are not using a peering leased circuit from themselves to UUNET SA NOCs to carry iBurst traffic (maybe they have a pipe/leased circuit between themselves & UUNET for non-iBurst traffic & plan to dump it or something - the force is not strong with me right now, so mind reading of WBS beast is at an all time low
).If this suspicion is true then both WBS & UUNET must be saving on not needing a leased circuit peering link, how much do these links actually cost? charged according to capacity, yes?
ic said:Totally interested
ok - have mailed the relevant account managers of the different ISPs asking if i can post a breakdown of their costs. So far, only Telkomsa have come back to me and they said NO!!!! IS and UUNET - still waiting. However, I will post the circuit prices tomorrow - dont wont to post the pricing we get because we are on the rate stability program with telkom and they charge us substantially less than what the man on the street pays.
and slimothy - you are wrong dude
there is SUBSTANTIAL difference in pricing on international connectivity depending what connectivity option you select. I will tell you this - a 512Mbs 1:1 Fibre link is over twice as expensive as a 1Mbs 1:6 Satellite link. Phone and ask DaveBuchanan1337
