The NBI (NBP) is now going to have a minimum speed of 500 as well. That leaves Eir, Vodafone, Airwire and Pure Telecom still with the 150 option available.

If every user was on 500 the total amount they download probably wouldn't change much but there would be higher spikes in usage for the ISP. Wouldn't it be additional cost to the ISP to upgrade to support these spikes?

shaveAbullock wrote: » Because they would be upgrading every customer. Where all the traffic meets on the ISP's backhaul would have to be upgraded wouldn't it? The contention ratio should never be obvious to the customer if done right.
limnam wrote: » What I mean is. If the minimum required to provide to a 1gb customer is 60mb and everyone is say on 150mb profile and they move them to a 1gb profile. They still only have to provide 60mb. The network would surley withstand that anyway.

shaveAbullock wrote: » No because that never happens in reality and it's not what an ISP would aim for because people will not pay full price to only get 60Mbit. When you go from most people on 150 to most on 500 then you have all the OLT's frequently coming close to max of 2GB, not an issue at the local level. But when all these lines of 32 customers are close to maxed more often that all connects at the ISPs backhaul and they would have to provide more bandwidth or people will see contention even if no one else on their 32 user line is active. Upgrading backhaul costs money driving up cost.

limnam wrote: » But it is the reality of the contention ratio no ?
oscarBravo wrote: » No. Contention ratio is a meaningless number. Nobody in the industry ever talks about it. Networks are designed and managed (by decent ISPs) to avoid congestion. The wholesale provider monitors the DSLAMs and OLTs to make sure that individual ports don't regularly exceed a given percentage of their capacity. Backhaul networks are similarly monitored, and any link that shows signs of reaching capacity is scheduled for upgrade. At least, that's the theory. No competent ISP - wholesale or retail - lets congestion affect customer experience and just ignores it because it fits within the parameters of a notional contention ratio.
