Daedalus Weekly Meeting, 17 Feb 95

Agenda

Quick status of Daedalus Net and plans for the week

• Latest information on WaveLAN handoffs (Srini)

Industry Meetings and Events

• Metricom contact (March 1 technical briefing on-campus)
  • Interested in collaboration, will send proposal and schedule follow-up meeting
  • Impediment to network build out is City of Berkeley -- have offered to help
• Digital contact: Dave Oran (Mobile software group)
  • Mobile desktop/middleware software
  • Reconcile-oriented file system, connection sensitive mail app, etc.
  • Possible follow-up contacts at DEC SRC
• Hughes Satellite Division
  • Direct Broadcast Satellite (VSAT for the 90's)
  • (Very) high bandwidth downlink, (very) high latency
  • Possible use of asymmetric access techniques (shared high bandwidth downlink, individual lower bandwidth uplink)
• Telesis Technology Labs (Week 2/27 or 3/6)
• BAGNet linkage (Randy meets with Bill Johnston next Thursday)
• Joe Kahn, EECS
  • 50 mbps IR downlink, developing 10 mbps system for InfoPad
  • 5 m limit for the high speed stuff, looking at even faster link speeds
  • Direct IR will be ubiquitous, 1 mbps, 4 mbps, 10 mbps speeds available
  • Handoff, spectrum re-use (time slot not frequency) is something of a problem
  • IR would have difficulty filling Soda Hall Atrium spaces
  • Further collaboration with Joe's group (Randy to make presentation)

Discussion of Security/Authentication Papers

• Some questions to consider:
  • Methods for fast authentication in overlays:
    • What is the node's name?
    • What is the registration procedure?
    • How to avoid reauthenticating back to the home systems?
  Dealing with mutually distrusting service providers
  • Limiting the amount of subscriber information exchanged across administrative domains?
  • Application may give up privacy to gain performance
