Franck Bonnassieux- WP7- n° 1 WP7 Budapest Collaboration with Dante Monitoring & R-GMA GridFTP Logging Network Cost Function MapCenter & TopoGRID Future plans

Franck Bonnassieux- WP7- n° 2 Close collaboration with DANTE DANTE expects stress traffic from experiments and performances cross-analysis with EDG Since July, WP7 has PCs in 3 POPs of Geant to test purpose : Network QOS : Scavenger (QBSS), IP Premium Bulk Transfers

Franck Bonnassieux- WP7- n° 3 Monitoring & R-GMA u Tools deployed on one node o f each testbed site, accessible by Web browser n Edg-pinger, edg-iperf & edg-udpmom u Publication of network metrics in MDS is done in release1.2 u Tests ongoing on publishing metrics in R-GMA (TB2) n Producer and Consumer has been set-up, Archiver is the next step

Franck Bonnassieux- WP7- n° 4 GridFTP logging Get actual end-to-end network transfers performances Logging of all file transfers (on RB, CE, SE) UI-RB RB-CE CE-SE (data access) SE-SE (data replication) Publication of metrics in MDS in release 1.3 R-GMA in release 2 Will be used by network cost function

Franck Bonnassieux- WP7- n° 5 Network Cost Function Function used by Resources brokers and Replica Managers to optimize grid resources usage getNetworkCosts(SE1, SE2, size) = time (and confidence level) Used by GetAccessCost (RB) and GetBestFile (WN) of WP2 Already delivered to WP2 and tested Close collaboration on-going Currently compute from TCP throughput measurement (iperf), and also from GridFTP logging for next release

Franck Bonnassieux- WP7- n° 6 MapCenter & TopoGRID (ccwp7.in2p3.fr) MapCenter New automatic version Queries each night from MDS/RB DataTAG, LBONE TopoGRID Compute from traceroutes Static & automatic version

Franck Bonnassieux- WP7- n° 7 WP7 Future Plan End Of September GridFTP logging End of October NetworkCost Function improvements (robustness and gridFTP logging usage) End of RGMA Testing End of December All network metrics (GridFTP included) in R-GMA. First quarter of 2003 NetworkCost from R-GMA Large usage of R-GMA possibilities (MapCenter, flows matrix…)
