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
