Did I read the ICASA document right? NO more bandwidth shaping?
The local bandwidth thing wasn't really a plus because we had free local bandwidth up until oct 2005, but the traffic shaping is a step forward no?
Yes but, there is nothing in those regulations which require Telkom to maintain the "quality" of the unshaped bandwidth. I have noticed over the past few months that on my shaped account i can pull full speed on torrents etc, the difference with unshaped is lower latency and jitter. I fear what will happen is telkom will abandon unshaped accounts and tell you that what you have currently is unshaped.
explain
I thought i just did!
well
wat i mean is I can find out all the info for my self ( i know the numbers of some specialists in TI - i dont waste my time with there dum agents). but im not sure what u mean.
**thinks you mean that they gonna make everyone’s shaped accounts unshaped**

What Daveogg is saying is that rather than Telkom upgrade everyone to a higher standard, they will simply lower the standards. Not sure if they can do that, because that would mean that current unshaped users would be "degraded" and people would notice. Not that that has stopped the evil force before...
Gangstar, sorry this is what i mean. Currently we have shaped bandwidth with certain protocols given priority over others. Shaping is an attempt by service providers to have higher contension ratios while maintaining service quality on certain popular protocols. Icasa has now ruled shaping unacceptable so Telkom will drop shaping, but in order to maintain service quality Telkom would have to drop contension ratios ie provision more bandwidth on the ADSL service. Unfortunately there does not seem to be any provision in the regulations which require Telkom to maintain the quality of service(except for some lofty statements that subscribers must negotiate a SLA with telkom).
So what i see happening is a dropping of shaping, with current bandwidth provision and a degraded service for everyone.

No currently its not in the public domain. In the regulations Telkom is suposed to declare the"contension ratio" quarterly on its web site, but of course Icasa fail to state what they means by contension ratio. Understand there is contension on your local dslam (100 1mpbs adsl lines but only 2mbps from the exchange to edge routers) contension on the ATM network. Contension on local access and contension on international bandwidth. So if telkom state their contension is 50:1 what will it mean?
Personally what would be great to know is the total amount of international bandwidth allocated to ADSL / total adsl connections.

And, to that you can add another "contention ratio". You can have x users on 1 line, or you can have x BW utilised on 1 line. In other words, if the line can support 2MB and you have two 1MB users "abusing" he line, you are fine - if you have 4 such users, each user only gets 50% service - on the other hand, in another area you may have 100 users using the line for email only, and they would get 100% service. Apples with oranges.
As I'm sure you'll know Telkom will have to publish key performance indicators including packet loss, average latency and jitter - as well as publishing contention ratios. Hopefully this will indicate if they're intentionally degrading the service.

again, useless info (not an attack on you, but an attack on Telkom).
50 WHAT users? 384/512/1024? What is a "line" - is is a standard entity? Is the cable "quality", distance etc a factor? Where does the line end? Is it from the DSLAM to a central point? Can the "second" line support the convergence of 10 * 50 user lines?
Smoke and mirrors.
Yes but how is that data going to be obtained. The beast is going to be reporting on the beast.
See gangstar this is exactually what i mean.
You are quoting contention at the dslam - that may or may not be relevant. I think more important is the contention on international bandwidth. Icasa by simply stating Telkom must provide "contention" ratio's and not specifying what they mean by that leaves it up to Telkom to interpret as they want, and quote the most acceptable figure whereas in reality there is a contention bottle neck further "upstream".
The ideas in the regulations have merit - no local cap, no shaping, performance critera etc, but they are so poorly thought out and so ambigious that Telkom can effectively do as it wishes.

even though the line/BW costs are the same? Doubtful.
I agree - that doesnt make sense.
Its is funny tho cause they using every possible way to decrease the load on international yet the international cost alot.erm.... dont insult the telkom mans intelligence
it is less. TRUST ME I KNOW
oh and the pice being the same... that is the biggest fu*kup telkom has done i dont know what they were thinking. but if u get the chance upgrade to business
