  1. Peering Simulation Game AFIX Technical Workshop Session 9

  2. Peering Simulation Game • Goal is to maximise bank holdings: the ISP with the largest balance at the end of the final round wins. • Make revenue by acquiring customers (squares on the game board). • Reduce transit costs by peering. AFIX Technical Workshop: Session 9

  3. The Board AFIX Technical Workshop: Session 9

  4. How to play • Roll the die and select that many adjacent squares (customers), starting from your own corner. • Each customer square you occupy gives transit revenue of $2000. • You pay transit fees for each square that other ISPs own. • When they reach an exchange point, two ISPs can negotiate peering. • The cost is two lost turns and $2000, which recurs at each turn. • ISPs can negotiate how this monetary cost is allocated. • Starting at the next turn, peering ISPs do not have to pay transit costs for each others’ squares. AFIX Technical Workshop: Session 9

  5. Let’s Play!

  6. How is this game different from peering reality? • The board is always visible so there is no bluffing during peering negotiations • ISPs move serially in the game, while in the real world action is parallel. • Squares are “overloaded” – they represent regional coverage and corresponding revenue, a quantum of traffic generated, and a quantum of traffic transitted to all others. In real life all customers are not equal in revenue, traffic, etc. AFIX Technical Workshop: Session 9

  7. Game vs Reality II • In the game customer transit revenue gained does not cause any additional financial load for the ISP. • Traffic quantum is a vague notion that ignores the asymmetric nature of traffic today. • Shared squares should cause revenue and costs to be divided. • Everyone starts with the same number of squares. • Everyone is financially backed to support infinite periods of financial loss. • If ISPs fail to peer they must pay transit to get access to other ISPs’ squares. In reality, content multi-homes allowing alternative paths to the same content. • Business motivations to sell transit instead of peer are ignored. AFIX Technical Workshop: Session 9
