1 AUGERnet definition and implementation René Bilhaut LAL-IN2P3

2 The global network infrastructure and network administration providing means of communication to the different on- site operational components : - Acquisition and detection sub-systems (FD, SD, CDAS) - CAMPUS facilities and external connection - On site voice-com facilities (VoIP ?) - Daily operations and maintenance routines What is AUGERnet ? Malargüe, April 2000 René Bilhaut LAL

3 We should follow these simple rules due to the constraints of the experiment (long time scale, minimal attendance) - modular architecture (independence between components) - standard solutions (“off the shelf products”) - open implementation (possibility to integrate new technology) How to do ?

5 Some recommendations and initial coordination Malargüe, April 2000 René Bilhaut LAL

6 passive infrastructure – within buildings --> foiled twisted pairs CAT5 (Fast Ethernet compliant) – between buildings --> fiber optic (electrical isolation) – patch panels and RJ45 plugs (common for computing and telephone connections) active infrastructure – Backbone based on a central High Speed SWITCH federating the different sub-systems (SD, FD …) and CAMPUS – In specific Ethernet segments (FD, SD, CAMPUS) SWICTH instead of HUB – Management via SNMP Agent Network infrastructure components Malargüe, April 2000 René Bilhaut LAL

7 Network administration components Basic technical coordination – definition of the IP environment – naming schemes and addressing schemes – IP routing and generic IP services (DNS, Mail, NFS, accounting …) – security policy (on the site, and with the rest of the Universe) Needs to coordinate “IP administrators” – one correspondent for each sub-system to set up a working group SD ( René Bilhaut) CDAS (Xavier Bertou) FD ( Nobert Kunka ?) Campus (Noberto Fazzini ?) Malargüe, April 2000 René Bilhaut LAL
