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

  11. 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
