Presentation And Fault Localizer Interactive Disturbance Localisation 2009 02 V03

  1. 1. Advanced Network Design AND FaultLocalizer Interactive Localization of Network Disturbances D. Kelly, 27 February 2009 AND – A technical introduction
  2. 2. Why network monitoring? Reduce maintenance costs  Detect Fault ASAP  Resolve network fault ASAP  Maintaining reliable multimedia networks  Comparison with incumbent telcos  Keeping customers online ...  ... keeping customers AND FaultLocalizer
  3. 3. AND FaultLocalizer Introduction Interface to network monitoring systems  Visualises alarms in network documentation  Alarms generated by NMS  Alarms manually generated in AND network documentation  Table overview of current alarms (filtering possible)  Alarm hotspots - geographical overview of current alarms  Comparison of performance data with AND calculations  Combines AND network simulation with live information  AND FaultLocalizer
  4. 4. Alarming & Monitoring Solutions Manual tracing for common cause failure  Transponder monitoring  Statistical analysis monitoring  Others  AND FaultLocalizer
  5. 5. Common Cause Failure Tracing in AND documentation Select problematic outlets  Colour coding denotes number of customers affected  Identify suspect device at common point  Change component’s operational status to disturbed  Alarm table is automatically updated  Corresponding hotspot alarm is activated  AND FaultLocalizer
  6. 6. Monitoring Solutions Transponder Monitoring Functions  Transponders strategically placed in active network components  amplifiers, power supply units, etc.  Pre-defined tolerance values stored in transponder  Network component monitors own performance  NMS polls transponder or trap is set in transponder.  If value lies outside tolerances NMS generates warning message  Market examples  ROSA, Cisco/SA  EMS, Teleste  KOM, Kathrein  Promptlink  Proxilliant (ingress measurement)  AND FaultLocalizer
  7. 7. Monitoring Solutions Statistical Analysis Monitoring Functions  Gather and analyse network traffic & performance data  Typically via cable modems and CMTS  Detects network issues based on analysis results  Market examples  ServAssure from Arris (previously Stargus, C-Cor CableEdge)  Auspice (recently acquired by Arris)  Visum from Teledesign, Brazil  AND interfaces  Provision of network structure data  Collected or exported?  Reception of alarm data  AND FaultLocalizer
  8. 8. Monitoring Solutions Other Solutions PathTrak, JDSU  Enables operator to identify ingress issues in upstream  Alarm information limited to fibre node  Handled similarly to transponder monitoring solutions  Hunter, Arcom Digital  Uses radar technology to identify location of network issues  Marker known as common path distortion (CPD)  Handled similarly to statistical analysis monitoring  CPD alarm with affected node and zone information  Ingress alarm with affected narrow zone information  Outage alarm based on node return signal processing  AND FaultLocalizer
  9. 9. AND FaultLocalizer IT Overview NMS Alarms Transponder Monitoring HFC Alarms NMS Network Statistical Analysis Monitoring NIS NIS CRM DaCo Interface SOAP I/F CRM AND SmartServer Database AND Data- Legend DaCo = Data Collector base NIS = Network Infrastructure = data flow between AND and NMS AND FaultLocalizer
  10. 10. AND FaultLocalizer Alarm Data Alarm ID (from NMS)  System ID (from NMS)  Component ID (from NMS)  Alarm message (from NMS)  Severity level status  Low (default), Medium, High  Alarm hierarchy status  Primary (default)  Secondary (i.e. follow-on alarm)  Alarm counter  Alarm acknowledge  AND Localizer
  11. 11. AND FaultLocalizer Alarm Table Functions Filter alarms to show specific region  e.g. Munich South Edit alarm states  Delete alarms  Search alarms  Acknowledge alarms  Hide/unhide  Secondary alarms  According to severity levels  According to NMS  Sort alarms  AND FaultLocalizer
  12. 12. AND FaultLocalizer Alarm Table AND FaultLocalizer
  13. 13. AND FaultLocalizer Alarm Hotspot Overview AND FaultLocalizer
  14. 14. Alarm Filtering Area filter for monitoring stations  Zip code  Determine monitoring source  Colour coded (user definable)  Hide/unhide alarms according to NMS  Determine severity level  Low (default), Medium, High  Hide/unhide alarms according to severity level  Distinguish between primary and secondary alarms  Evaluation by AND  Hide/unhide secondary alarms  AND FaultLocalizer
  15. 15. Alarm Management Provisioning monitored components in AND  Monitored Component ID  System ID of NMS  Uniqueness of Component ID verified  Informing service staff  E.g. E-mail to service staff on priority issues  Informing call desk  Determine affected subscribers  Address forward to CRM  Keeping customers updated  AND FaultLocalizer
  16. 16. Future Developments Populating transponder with threshold values  Network documentation updates taken into consideration  Real time level queries  Real-time values comparison with AND calculations.  Calling up NMS from AND  Accessing further information  AND FaultLocalizer
