Peering and Network Cost

Fri Apr 17 13:05:21 UTC 2015

One more interesting thing.

If you buy IP transit, mostly you are paying by exact bandwidth, per
megabit. If you buy IX peering port, you are paying for port. This means
Tranist ports are overloaded or close to it, while IX ports usually
always have some extra free capacity.

In practice, this mean if your customer download some file using IX way,
speed will be much higher that same file reachable by IP transit.

So more peerings your uplink use - better performance of your network
connection you have ;)
