Agenda

This meeting has 3 main sections and then a Developers section which is optional for those not interested in the hardcore tech issues.

SOWN Projects Group (SOWN-PG)

• Progress on:
  • VOIP
  • 802.1x
  • Location Tracking

Other Issues

• SOWN press release
• SOWN Polo Shirts
• Response to emails for problematic nodes.

Lead Developers

• Email list for node admins

• Power problem with XR5s on a Cigarette-Lighter-socket powered-node
  • Can we power these boards over POE?
  • How can we do range testing? (Separate car-battery | Generator? | Other-battery-pack)

• Throughput problem for IPv6 on home-nodes, will this degrade user-experience?
  • This isn't a CPU-load problem, it barely hits 20% usage.
  • Do the University/Janet honour a differential-services 'assured-forwarding' class?
  • Test results:

AF	v4	v6
NO AF	182Kb/s	40Kb/s
AF22	219Kb/s	45Kb/s
AF11	179Kb/s	46Kb/s

• • Conclusion: no desirable change. I assume we have an efficiency problem with v6 packets in Openvpn v4 tunnels, perhaps the MTU needs tweaking. Further investigation required.

• AOB
