CSDB Fiber Module IT-CS-CT CERN IT Department CH-1211 Genève 23 Switzerland www. cern. ch/it
Introduction • CS group – Large infrastructure (network, telephony, Wi-Fi) • 3250 network equipment (switches, routers, PABX, …) • 950 Wi-Fi station • 12000 fixed phones / 5700 mobile phones – Limited staffing Automation + Simplified management + Robustness 2
Introduction • CT section (7 people) – Software for automation – Critical applications • CERN network and telephony depend on these High turnover + Flexible to new user demands 3

Introduction More than 200 tables 6
Continuous consolidation strategy • Programming languages – Java, Perl, PL/SQL, Web (JS, HTML, …) • Technologies – Web, Rich Client, command line • Architectures • Software development life cycle (SDLC) Knowledge consolidation 7
SDLC 8
Fiber management Existing system: • 990 trunks registered • 1470 channels • 22910 fibers • Focus on the function of the fibres. • What fibres exists, status, and function. • Logical paths of connections of devices port-to-port 9
Future • Starpoints not enough • Control Panels and fibres inside a building (specially CC, To. R panels). • Evolving current system and data – In-house team, flexible evolution. 10
