(Please forgive me if I am using inaccurate information... I'm just using
there as an example.)
Not necessarily. Take Ocean as an example. I believe they have links with
UUnet for their bandwidth. If a small company has a 256K leased line with
them, there is no much point shipping their traffic, destined for an IOL
customer through England or some other European country. They should use
And just because they (the Big Telco) are linked into INEX does not mean
people will be able to use their bandwidth free.
Small Irish ISP - 10MB link to INEX - 10 MB link to Europe or States
Big Telco - 10MB link to INEX - 100MB link to Europe or States
If a client of the smaller ISP wants to get to a European website, the
smaller ISP will not be allowed (unless they have agreements) to ship the
data through the Big Telco, via INEX. But they will get the advantage of
decreased latency to one of the Big Telco's customers down the road.
Small customers still sometimes have links to the big people. It's a lot
cheaper to link to a local Telco with a 2MB link, than a 2MB link to outside
