Responsibilities

Providing DebConf13 with all needed technical infrastructure, in collaboration with Debian and DebConf ressources

• Network infrastructure
  • Secure high-bandwidth network connectivity at the venue
  • Consider backup options with multiple uplinks
  • Local networking (wired and wireless)
  • Local network services (DNS/DHCP, mirrors, storage, video team, ...)
• Talks infrastructure
  • Network for Video Team
• Website
  • Technical side of the coin

Schedule of the work

Ask LeCamp for:

• Contract details with ISP (hug working on it)
• Find space for a few servers (no special requirements, "1 room")

Ask ISP for:

• Existing RJ45 cabling between rooms, especially around the talk rooms (→ separate video team network)
• Plan of network setup (switches, APs)
• /22 public IPs for the wireless network (around 700-1000 devices)
• /29 to /27 public IPs for the server stuff (no firewall!)
• Is running our own DHCP/DNS servers (e.g. for the wireless) fine?
• Routing between Wireless and Wired must be local for video streaming
• SLA? How to make sure we have internet over the weekend. Are they willing to support us or should we run the network ourselves?
• Can we have native ipv6

Answers from ISP: (unfortunately not more than the following info)

• current setup: 64 IP addresses (contract says 1 IP though), ipv4-only
• 100MBit symmetric over fibre
• Wireless has multiple SSID and they could configure one without captive portal

Ask Thomas Krenn for:

• Server sponsorship (Ganneff will do)

Needed resources

(Necessary resources, as well human as financial or technical)

• Non-firewalled IPv4-Uplink with at least /29, preferably /27
• Nice to have non-NATted /22 IPv4 network for participants (/23 is ok, too)
• (optional) native IPv6 uplink with /48
• Switches (Hacklab: per table 8-16ports PoE, distribution per room 16port PoE injector, core)
• Separate Video-Team switches (separate STP and subnet)
• Space for 3-5 servers + switches

Offered resources

• Chaostreff Basel asked if they should lend us (wired) network infrastructure hardware. They have at least 10x 48 ports 100 MBit switches with 1 GBit upstream, plus gbic modules and fibre cables. (Axel's contact at Chaostreff Basel: Obri)
• CCC EventWLAN via CCC Basel https://eventwlan.cccmz.de
• Brocade switches and laser wireless hardware (contact: hug)

Connections with other subteams

(How does this team interact with others: what are his expectations and what will it provide to other teams.)

• DebConf.org (including sub-domains) infrastructure
  • Getting access
  • Being allowed to hack :->
  • Technical support in both directions
• Talks infrastructure
  • Making sure needs and expectations are clear in both directions
  • Getting to know precisely what hardware is needed / is provided / has yet to be provided
  • support the video team to deliver videos to the world

Team Meetings

• (list of meetings, to be created as subpages of the subteam)
