Question on 95th percentile and Over-usage transit

*//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

The fact that the NomCom is so closely coupled with the existing leadership has an unfortunate appearance that suggests a bias.  I'm unable to say whether the bias exists, is recognized, and/or is reflected in the slate of candidates.  But it seems like an easy enough thing to avoid.

I have my own opinions on why this is, but they aren't worth elaborating at this time - in fact, I suspect many ARIN members here on NANOG can speak for themselves if they wanted to.  In any case, this is just my impression.  If you would rather share some statistics on member participation, election fairness, etc, then such facts might be more useful.

For these reasons I previously noted that "ARIN has a pretty good governance structure" and I continue to think so.  It could be improved by increased member involvement, as well as broader involvement from the community. (For instance, policy petitions should include responses from the entire affected community, not just PPML.)  But my criticisms should be interpreted as constructive, and are not an indictment of the whole approach.

It takes almost no effort to join PPML, support a petition, and then leave PPML if you are that determined not to participate. Further, I think that it is reasonable to expect at least a modicum of participation in the policy process in order to participate in the petition process. Requiring supporters to be on PPML at the time they support the petition seems like a reasonable threshold to me. Finally, absent some mechanism such as requiring a PPML subscription, it might be somewhat difficult to avoid petition stuffing.
