What two layers ? Are you saying then that BigTelcos don't sell
direct to end customers ?

What about mister huge global corporate software company that has
a policy of only buying bandwidth from BigTelco... where is his
local peering in Ireland ?
He doesn't qualify as an ISP so he can't join INEX... and anyway
why should he have to join INEX to get national peering - why
can't his ISP do that for him ?
Anyway - you can't split the network into 'big' and 'small', and force
all the customers to buy though 'small'..
So while your point is argued well, your basis is flawed. There are no
layers.. It might be fair to talk about layering in the USA context, but
then you're dealing with USA national traffic... and 'Tier 1' designations
apply... but the Internet doesn't only exist in the USA... so within the
context of Ireland Mr BigTelco is (as you rightly point out) not building
a national network... so he needs to do in Ireland - what the Irish ISPs
have to do in the USA... go to someone who has a national network and
buy Irish transit from them... but it doesn't work that way - cause the
big guys just bully their way around - and refuse to play fair with the
In the Irish context the national 'tier one' networks are the Eircom
(Eircom Net / Indigo), the Esat (Esat Net, IOL/PostGEM) and the HEAnet
Arriving into a country, connecting up two customers locally and then
claiming that you are servicing the country but can't route traffic
locally within the country is what caused the erroneous statement from
microsoft in the first place.
Are you claiming that 'BigTelcos' peering at LINX and AMS-IX is somehow
more efficient that them peering at INEX ?
