  • Wifi in the keynote: This is how it is done

    Date: 2011.08.30 | Category: Uncategorized | Response: 0

    This is how it is done.

    We had just shy of 1000 concurrent users in the keynote. All the while everyone was tweeting, uploading photos and we were still getting 1-2ms pings to Charlotte Street exchange in Brisbane.

    As Borat would say, “Niiiiicee.”

  • auteched + apc 2011 Network Design

    People often ask me for more information about the network design and implementation for tech•ed and APC.

    I finished off the physical design for the MDF and IDFs a while ago and thought I would take the time to post these in case you wanted to build your own 3000 person corporate conference at home. I am only covering off the network side of things below – there is a massive HP + Microsoft private cloud solution going in at the event that will need post(s) in its own right.

    In terms of fast Internets

    • 1000 mbps of Internet connectivity provided by Telstra Internet Direct. This is a high performance e-line service back to Telstra Internet Direct in the Charlotte St exchange (i.e. it is a wholesale/service-provider quality service, uncontended back to their core).
    • An additional 500 mbps of Internet connectivity from Over The Wire as a redundancy option.
    • BGP routing under our own AS9984 to make the best use of the combined link.
    • IPv4 and IPv6.

    In terms of WiFi

    • Cisco 5508 WLC
    • 50 x Cisco Aironet 1252 access points
    • Each AP has 2 x radio interfaces (2.4 and 5GHz) for a total of 100 radios supporting 802.11a, b, g, and n

    In terms of physical infrastructure

    • 2 x Brocade CER units for core routing
    • 2 gbps LACP core trunking between the routers, core switches and wireless LAN controller
    • 1 gbps distribution network
    • 77 switches deploying 2000+ ports of connectivity
