LBE/Scavenger I2 demo
  • Presentation by Lada Lhotka (CESNET)
  • Suggestion for SC2002, Nov 16th-gt

12
LBE scenario discussion
  • Where might we use LBE first?
  • (implied usage of TCP not UDP!)
  • Bulk data transfer (GRID)
  • Data mirrors, FTP servers
  • Separating production and test traffic
  • Support of new transport protocols (TCP tuning)
  • Student dormitory networks (enforced)
  • Remote network backups
  • Non-disruptive available bandwidth measure?
  • Others? Where is the real congestion?
  • Possibility to run IPv6 LBE in 6NET WP4
