Minutes of Working Group Meeting

IfA, Hilo

December 7, 2000




  1. Current Network Status
  2. There are no problems to report. During the revolving power outage on the Big Island, the IfA building's UPS was able to keep the network up at all times.

    There was a delay in the ordering of the backup serial card, but shipping is expected in a couple of weeks. This serial card is to be installed in the HP router as a backup for the 45 Mbps ATM link.

    We encountered more problems with the fiber connection between HP and the visitor station. SMA is getting more equipment to help us resolve the problem.

  3. DCHP server at HP
  4. Ryusuke Ogasawara of Subaru has set up a DHCP server at HP. Since all of HP is sharing one subnet, the server will be available for guests of all organizations. However, Subaru does not have enough IP numbers for everyone. Anyone who has some IP numbers to spare were asked to contact Ryu.

  5. Hilo Based Network Support
  6. There are three applicants this time around. None of the applicants has the experience that we would like. The decision was to withdraw the position and hire one of the applicants as a student help for now. The applicant, Ms Miranda Hawarden-Ogata, cannot be hired as a full-time employee due to her full-time-student status at UH. The position will be re-advertised at a later date.

  7. Summary from the MKO Users' Committee Meeting
  8. Pui Hin Rhoads gave a summary of her report at the 2000 MKO Users' Meeting on the future of MKOCN and its connection to the Internet. Here are the main points:

    1. The Summit loop

      • existing OC3s should be sufficient for a while
      • existing cable plant will serve us for a long time, advancement in optical networking, e.g. Dense Wavelength Division Multiplexing, will allow very high bandwidth on existing fibers.

    2. HawTel SONET (10-year contract expires in August 2008)

      • pricing remains competitive in the short term
      • in the long term, bandwidth depends on termination equipment
      • Ryusuke Ogasawara asked how many of the 11 1/2 DS3s are still available.

        Here's the current status:

        One DS3 is allocated to each organization: CFHT, Gemini, IfA/IRTF, JAC, Keck and SMA.

        One DS3 is reserved for contingency.

        One DS3 is used to complete the Internet access link from the summit to Manoa.

        Keck has requested a second DS3.

        This makes a total of nine leaving two spares available to any organizations which wish to buy a second DS3.

    3. Big Island to Manoa

      UH-ITS has procured a microwave system that will provide OC3 services to Maui and the Big Island. The termination point on the Big Island is at UH Hilo. Pui Hin is working with UH Hilo to pull fiber between the IfA Hilo building and UH Hilo in a joint project.

    4. To the Mainland

      UH has procured two OC3s from Oahu to the Mainland - the first one will be available April 2001; the second one will be available later in the year.

  9. Wireless Network
  10. Pui Hin reported that several facilities have expressed an interest in using the wireless technology for their in-building local-area networks at the Summit, mainly in shop areas where laptops are often moved around. The specific hardware being considered are the Cisco Aironet 340 Series Client Adapters and Access. Data sheets were passed out to everyone. Pui Hin asked if anyone present knows enough about this equipment to determine whether they will interfere with the radio and submm telescopes. Henry Stilmack said he will check with his colleaques. Pui Hin explained that Bob McLaren has been informed of these interests and he will be soliciting comments from the directors.

  11. I2 Technical Meeting - Astronomy BoF
  12. An I2 technical workshop will be held at the East-West Center January 28-31, 2001. If there's enough interest, a BoF for remote observing will be held on Wednesday, January 31st. Registration fee is $100 for the workshop. There will be no charge for anyone who just wants to attend the BoF.

  13. Next Meeting
  14. March 8, 2001, 10:00 a.m., at CFHT
Frank Dagosti of Cisco gave a presentation on optical networks following the meeting.
