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
