Timeline• 2010.02 – Project started• 2010.08 – Visit in HP Montreal• 2010.11 – Technical report, change of scope, first
collection system, initial performance metrics• 2011.11 – Radio channel counters added by HP,
change of scope• 2011.12 – First rule based diagnostic engine• 2012.10 – Technical report, findings, deliverables• 2012.11 – Visit in Canada, knowledge transfer• 2013.01 – WIND as a tool for network engineers
Global perspective of WLAN deployment
• User perspective of the network (with history)
• Remote diagnostics• List of probable problem causes• Broad range of problems detected
• Assessment of WLAN health:– Reduced number of site surveys– Proactive monitoring (interference, rogues)– “What-if” analysis– Without probes!
WIND saves time, resources and money!
• State of the art WiFi monitoring and diagnosis tools
• Extensive feedback to WiFi Service manager• Valuable feedback to HP• Two technical reports, procedures,
suggestions, know-how• WIND as a service for WiFi monitoring and
troubleshooting
WIND’s legacy
• Big thank you to HP for an excellent collaboration
• Big thank you to CERN CS group for:– tolerating our experiments – help and ideas provided– testing of our tools
