What is IPC and how does it work?

Are these questions too difficult or shouldn’t I have asked them? :)

Lynx_ZA highlighted a contentious topic with regard to the purchasing of IPC.

  1. How often does ISP’s review their business model to be in line with the number of customers they have?
  2. Is it possible for ISP’s to purchase additional IPC on short notice to address shortfalls they may have?
  3. Does Telkom Wholesale limit the minimum amount of IPC which can be purchased?
  4. What is the minimum period IPC can be purchased for?
  5. Does Telkom Wholesale allow ISP’s to purchase additional IPC for specific days when they expect to encounter shortfalls? (e.g. Month ends or with special events)
 
Yup, even more questions. :)
  1. Does limited IPC affect ping rates?
  2. If I do a speed test with ISP “A” and ISP “B” and the results are totally different can it be contributed to insufficient IPC?
  3. Does correct routing play an important role in IPC?

1. Most definitely.
2. Yes. (one of the reasons)
3. Yes.

Thank you MickeyD.
Would you mind elaborating what the other reasons could be for different results?

There can be a hundred. Depends on the network architecture, and you won't get that sort of info from anyone as it is proprietary information.

Thank you Crystal Web. :)

I didn’t know that it is privileged information. Does my questions with regards to the acquisition of IPC fall in the same category?

Which one? You've asked dozens so far. :D

Review? Hourly. But this isn't a business model review. Reviewing a business model is something completely different to reviewing capacity. I say hourly, but this is dependent on the ISP.
Short notice IPC? Um, yes and no. Far too complex to answer simply
IPC limit? This was covered already afaik - you can buy what you like if you and Telkom both have the infrastructure available to provision the capacity
Minimum period? This is a contract question and one that is proprietary
Specific days IPC? No.
 
Thanks again Crystal Web for your valued input. :)

My earlier question established the maximum limit whereas the latest one was aimed at the minimum.

From all the answers I’ve received in the thread it seems that ISP’s will have a difficult task to balance the expectations of their customers and the sustainability of their business.
I wish you only the best and may you be very successful.

The ISP's do have a tuff time I do agree...but, they all here to make the $ so don't only blame Telkom for your poor internet experience

If you an ISP the mandate is simple...generate as much revenue from your purchased capacity as possible. The only difference in my opinion between ISP's is how they go about achieving this mandate.

I started this thread understand how IPC works and I did not blame Telkom for poor service. All references to Telkom was made to find out how they manage and sell IPC to ISP’s.
 
The older Telkom Distrobution Boxes run copper all the way back to the main exchange, However DSLAM's and MSAN's run fibre directly from the main exchange to the DP Box at the end of the road.

Wait, stop. Does this mean that all SDCs will get a DSLAM/MSAN? Right now my copper length is about 7km to the exchange, but 200m to the SDC. Does that mean there is hope for me?

Edit: I mean DSLAM or MSAN, not just DSLAM.

Eventually yes. We get planned work requests every day for ME upgrades at the exchange level. Slow but its happening.
What a glorious day that would be.

Please distribute a memo that most doctors told me that they expected me to die 10 years ago.

Time is running out for me.

Current scenario:
1. All SDCs do eventually link to a DSLAM.
2. Most DSLAMs are in the exchange building (Central Office - CO)

Future scenario:
(All exchange areas have been rated.)
1. Top exchanges: All SDCs and DSLAMs are replaced by MSAN/ISAM units.
2. Next lot of exchanges: Central Office DSLAMs are replaced with MSAN/ISAM units and some of the SDCs are replaced with MSAN/ISAM units. The remaining SDCs are linked to the closest MSAN/ISAM unit.
3. Next lot of exchanges: Only the CO DSLAMs are replaced with MSAN/ISAM units. All SDCs remain in the firld and are linked to the CO units.
4. Next lot of exchanges: Everything stays as is.
5. Bottom rated exchanges: Recover/sell everything and offer LTE as the only broadband product.
 
/SNIP

Number 5 is for areas where the number of active ports on an exchange is very low so it is not feasible to continue servicing those areas.

From what I know, They are only fazing them out when equipment goes faulty, I still haven't received EOL dates yet.

And mainly rural and deep rural, yes...

It is also coupled to the property rationalization project.
 
Thread necro! (blame the CW thread for that...)

MickeyD's suggestion that spare IPC be reduced in price and sold on is a good one. I'd actually go a step further and suggest massive ESR upgrades for the cross-connects into the metro ethernet IPC handover, and then push "spare" capacity over an exchange, like a financial markets exchange. As long as the ESRs can handle the throughput, and your own ISP/IAP core network can handle the capacity, you should be able to purchase IPC in a truly free market environment via supply and demand pricing and on an ad-hoc basis. Once done, you list your spare capacity for resale on the same market. It is after all a temporary monetisation of unused capacity, and future orders for permanent capacity deplete from this pool as well. Moreover, if ISPs connected better one could on-sell spare capacity like this on a dynamic basis. But then again, why invest in a limited lifespan product to such an extent? And why would Telkom allow this? It would replace their traditional retail model and remove their pricing control as well. So very much pie in the sky thinking here. Also some serious implementation issues I'm not bringing up.

How was that for a prediction ??! :D

Last month Telkom offered to double all ISP's IPC capacity for 15% extra on their current cost.

(eg. R100 for x and now R115 for 2x)
