Participants are divided in teams, simulating simple network infrastructures (eg. computers connected by an hub and a switch). Every player has a role: a PC or mobile phone, an HUB, a Switch, a Router, and must communicate with the others following the associate specification (eg. an hub should broadcast message to every neighbour, a switch should populate the mac address table, ...) The team which is faster in exchanging messages wins.
