Presentation Transcript

  1. ATF - WP7 - Status • 3 tools deployed on TB1 (CERN, NIKHEF, CNAF, CC-LYON, …) • Pinger (RTT + packet loss) • Iperf (TCP throughput) • Udpmon (UDP throughput) • Publication of network metrics in MDS • LDAP backend delivered and deployed for pinger • LDAP backend ready for Iperf and Udpmon

  2. ATF - WP7 - Dependencies • WP1 • WP 7 must provide a network closeness function for resource broker • CE <-> SE • WP 2 • WP 7 must provide a network closeness function for replica manager • SE <-> SE • WP 3 • WP7 is Provider of information for MDS / R-GMA • WP7 is Consumer for MapCenter / NetSaint • WP7 is Consumer for elaborated functions (closeness ?)

  3. ATF - WP7 - Vagueness • Provisioning • Streams identification (CE, SE, MS, RB, II, MDS….) • What is a SE (node, mass storage, service ??) • Traffic measurement issues (e.g. CERN testbed) TB1 functional issues TB2 performances ?? • Presentation layer : metrics / availability • MapCenter • NetSaint • Usage of networks metrics • Publication to MDS, and then R-GMA ??? • By WP1 and WP2 ? • E.g. : networkcost (SE1, SE2, Filesize)
