Minutes of Working Group Meeting

CFHT Base Facility, Waimea

September 9, 2004




  1. Current Network Status
  2. There were a number of problems to report:

    On July 15th the connection to the Internet was disrupted by routing problems. The problems started around 4 pm and lasted for about 50 minutes.

    On August 19th the connection to the summit was lost at about 12:30 pm due to the on-going problems with the CFHT router. The only difference this time was that none of the usual tricks worked. The problem was temporarily solved by removing the CFHT router from the ATM switch. The CFHT router was replaced that evening. Miranda's assistance at the summit until well after 10:00 pm is greatly appreciated.

    On September 1st, a DOS attack originating from the Manoa, Kauai, and Leeward campuses caused sporadic network outages. It started around 12:50 pm and lasted for about 10 minutes.

  3. Southern Cross 10Gbps dual rings -- Connection to MK Observatiories
  4. While still waiting for the outcome of the NSF proposal submitted by UH-ITS in conjunction with USC and UW in May, a second funding opportunity has turned up. CANARIE Inc. -- Canada's advanced Internet development organization -- is very interested in taking advantage of the Southern Cross Transport to improve the connection between CFHT and Canada's National Research Council; where all of CFHT's archiving is done. CANARIE, UH-ITS, and AARNet plan to meet in early February to hatch out a cooperative effort to improve the connection to the MK Observatories.

    Using the latest pricing from Verizon -- and assumming some funding from NSF and CANARIE -- Pui Hin discussed various ways the summit, Hilo and Waimea might be connected.

  5. Wireless Implementation at HP
  6. Pui Hin reported that the connection to the VIS hasn't had any problems after the Eucalytus tree was cut down in June. It remains to be seen if the problems reoccur during the winter months.

    For the common area, Pui Hin continues to have routing problems with NAT. However, the wireless implementation without NAT is fully functional. The installation is currently open for public use. More work will be done, perhaps with additional equipment, for a NAT implementation. Again, the wireless network is completely separate from the wire based network and is restricted to 10 Mbps bandwidth.

    For the dormitory -- because of the problem of getting wireless signals through the dormitory walls -- Pui Hin has looked into other technologies such as Ethernet over powerlines and phones. Her conclusion is that these technologies are not suitable for HP. She recommended installation of fiber between the main building and the dormitory buildings and Cat6 cables into the rooms. A wired network is also more secure and easier to maintain for remote management. This suggestion was endorsed by the group.

  7. Extension of Mauna Kea Observatiories DS-3 Verizon Services Agreement
  8. Pui Hin distributed handouts with revised pricing for the Verizon VON service. The pricing for Hilo has gone down even more than before while pricing for Waimea has gone up a little. The explanation from Verizon is that they made an error on their earlier mileage calculations for Waimea. For Hilo, the price for 100 Mbps Ethernet is now lower than a DS-3. Interested observatories should contact Verizon directly to make upgrade arrangements.

  9. Next meeting
  10. December 9th Thursday, 10:00 AM at Gemini, Hilo
