– Aim to integrate results into full QOS-2003 paper• Notification of acceptance by Nov 20th

Limerick resolutions

• Joint meeting including Internet2 people– Special TNC2002 BoF session

• Proposals– Agree common DSCP (001000)– Implement transparency GÉANT-Abilene– Suggest DSCP usage “policy” to IETF(!)

• DSCP (8) and transparency achieved• Seeking demonstrator for GEANT to I2

– Demonstrate bulk data transfer– Simultaneous “live” application use

LBE/Scavenger I2 demo

• Presentation by Lada Lhotka (CESNET)– Suggestion for SC2002, Nov 16th->

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
