The document describes a peering simulation game where players take turns rolling dice to expand their transit networks and negotiate peering agreements. In the sample rounds: - ISP A expanded its network to 9 squares, peered with ISP C to reduce costs, and had $9,000 in revenue after round 1. - ISP B had no revenue after round 1. - ISP C had $3,000 in revenue after round 1 and $5,000 after round 2 where it peered with ISP A. - ISP D had -$13,000 after round 1 from paying high transit fees. The game teaches peering strategies and terminology.

4. 3 Rules
1. Goal: Maximize bank holdings. Make money by
acquiring customers and reduce transit costs by
peering
2. Play: Roll the dice and expand your network by
selecting that many adjacent “squares” of
customers
Gain transit revenue of $2000 for each customer
square you own
Pay transit fees of $1000 for each square of traffic
that other ISPs own
3. If at Exchange Point, two ISPs can negotiate
peering:
– $2000 recurring cost and loss of 2 turns, ISPs
negotiates who covers the costs of peering Quick round…
