DreamHack behind the scenes: network

Published on June 21st, 2011

We got a chance to talk to two very important people of the DreamHack organisation: Karl en Rok from the network team.

They will briefly explain the layout of the network, the hardware used and the troubles they faced during the building of a complex network that has the most demanding users, which had to be build in a very short amount of time.

    Nice video, seems they worked out the traffic really good. Have been on lans it was just terrible!

    Nice video explaining all the details.
    I’m probably missing something. But on the weathermap, why doesn’t the traffic to/from the two corners/internet routers match with the internal traffic?

    Or is it simply just a partial map of some backbone switches where a large part of visitor/table switches are connected (through a few layers) directly to those two routers?

    Ive seen more activity on the Campzone network map 😛

    Alex, great observation. Exactly as you guessed this map doesn’t show all equipment connected to the core routers. In fact it lacks the main 3750E aggregaion switches for almost 2/3:s of the participents. I’m not sure why those weren’t added to the weather map, I’d guess it’s because of the new design of this event and is something that we have to do better next time.

    Very interesting.

    About your security: Can’t the sending of the key be sniffed since it’s on the open network? Then they can listen to all encrypted traffic as well.

    Wow at the 50% traffic load on those 10G links.

    @Roel

    Yes, but as I thought and Rok explained, this is not the full graph. It actually lacks most of the visitor traffic. And they do have a much bigger Internet pipe (separate, let alone combined).

    @kaazZ

    Glad to hear you liked it :)
    That is correct we use the AIR-LAP1142N-E-K9 and the AIR-LAP1262N-E-K9. For controlling them we use a WLC.
