a central high-speed glass fiber switch, with cables to sub-switches on each field. Those field switches are operated and supervised by the field admins for that particular field. Connected computers needed to manually configure a fixed IP address for the network. The core of the network, as well as many servers brought by visitors, resided in the Network Heardquarters (NHQ), a temporary air-conditioned building. Wireless network access and Internet were also available at CampZone 7 (although limited). For the next edition, an entirely new network has been designed. The new network is a routed network. Each field gets its own high-speed switch (HP Procure 9300 series) which are interconnected using 8 to 20 gigabit links. Every end-user switch has its own subnet so that network issues remain local problems and do not affect the entire network, as well as limiting unneeded broadcast traffic. Also, DHCP is used, removing the need to manually configure IP addresses. In order to allow for certain types of broadcast traffic, a custom-built system is used that relays certain packets (such as gameserver discovery packets) across the entire network. In addition, thanks to the high speeds at which fields are connected, every participant can use gigabit ethernet to connect their own PC to the network. Previously gigabit connections were available in few numbers and reserved for people who shared the link with several others. Altogether this should prove for a much more advanced, faster, more stable network. Power Since there is no normal power source at the location of CampZone, the power has to be generated there. The entire event greatly depends on trustworthy stable power, because computers and other hardware can very easily damage when the current fluctuates, or is not properly aligned or consequent. Some power usage facts of CampZone 7 (2007): 4x 250 kVA generators, which are linked together. The generators were configured so that the next one automatically starts when the other ones are at 80% capacity. 30.000 litre (7925 US gallon) diesel was used by the generators. A total of about 250 16 amp groups available for visitors (each shared by ≈5 people). power cable in various diameters. Competitions and activities During the event, many official and unofficial competitions are held. The official PC competitions are organized by the CampZone crew. All official competitions offer prizes for at least the winner, most of which are provided by sponsors. The official outdoor
