Re: Question on 95th percentile and Over-usage transit

[Pradeep Bangera <pradeep.bangera () imdea org>]

*//Sorry for the earlier misguiding email subject//*

Dear All,

Thanks for all the replies! I would like to see more, to learn more!

Since I (Research Assistant) am not from network operations and
management domain, I am trying to model the transit pricing function. In
my research work, I am using a pricing model from this work! This
pricing model is as follows:-- Transit price = Constant * (aggregate
traffic)^0.75, which is exactly similar to the one described by Ryan
Malayter in his earlier message. Hence I am wondering, whether the
pricing should be a linear(CDR*[95th peak]) or sub-linear (like the
above)?

With Regards
Pradeep
