Inside the World's Largest LAN Party

MrSeb writes "Last weekend, over 12,000 LAN party goers turned up at DreamHack Winter 2011 in Jonkoping, Sweden with a PC under the arm, on their back, or packed carefully in the trunk of their car. Every single attendee is squeezed into just three massive halls — the largest holding 5,000 computers — or four days, only taking brief breaks to sleep or check out one of the many stages (including some of the largest e-sport tournaments of the year). Being the largest LAN party in the world, DreamHack's infrastructure is suitably monumental: it takes days to lay the thousands of cables, and at the heart of the network is tower of Cisco routers that interface with a 120Gbps internet connection provided by Telia."

He would make some space in the living room by moving a couch to the side and getting one or two large tables in with some chairs. Ideally he would also stock up the fridge with drinks and have a hub or a switch (With at least 12 ports).

On very rare ocation we would decide during organisation stage on what games would be installed, but in majority of cases everyone would just bring their entire collection of CDs and external hard drives with pirated games. Some extra cables also come in handy because as a rule at least someone will forget a power strip or a network cable.

    First half of the day would consist of assembling everyone's machines and installing/copying whatever games we decide we will be playing. Normally everyone would have their drives fully shared, so after the software are installed everyone just browses each other's PCs and external drives for anything interesting to copy (Movies, games, music, porn, etc). Once everyone finishes installing the games/had their fill of copying the we start plaing games. Starcraft, Quake 2, Counter Strike, Total Annihilation were very popular choises.
