Dude, how are you going to weigh up the costs and benefits of peering
if you don't include the "costs". I refer you back to the same
documented I referred you to yesterday...

This time look at section 4 of this huge and hard to navigate
document, "4. Peering Costs":

Loosely extrapolating:

Network transport: You need to be physically connected unless you
blagged space in the same rack and can patch in for free.

Hardware: You need tin to route packets.

Software: You need software to monitor the packet routing.

Colocation: You need space/power/cooler/security in which the tin can operate.

Staffing costs: Someone has to configure that tin.

Admin/engineering overhead: Someone has to manage the peering process

Peering port: You probably have to pay to peer.

Reseller ports: You might need remote connectivity to the LAN and
"network transport" above would refer to a cross connect to the remote
peering provider instead of directly into the IXP LAN.
