  1. Using Volunteer Computing for monitoring Broadband QoSE Chanuka Wattegama and Nilusha Kapugama This work was carried out with the aid of a grant from the International Development Research Centre, Canada and the Department for International Development, UK.

  2. Agenda Monitoring Quality of Service Experience (QoSE) : possible approaches Monitoring QoSE: through demand-side testing Volunteer Computing for data gathering Results: from USA and India Conclusion

  3. We measure QoSE: from the demand (user) side, objective and quantifiable QoSE: Quality of Service Experience An objective measure of user’s experience of delivered quality with or without reference to promised levels. Quality of Experience Quality of Service

  4. Possible ways to monitoring quality +++ High ++ Medium + low - none

  5. Relevant metrics for testing +++ Highly Relevant ++ very relevant + relevant - not relevant

  6. Available Software Applications monitor… Application Developed by IIT-Madras uses 6 Metrics

  7. Methodology contd… Software freely available for download Multiple measures of each metric taken during a day The time and day is recorded and reported to check for Peak/Off peak variations Location is recorded to measure regional variations The metrics are measured in three domains; ISP, National, International

  8. The 3 test domains… Internet 203.208.151.xxx Network Solutions (USA) Singtel (Singapore) Yahoo 220.247.232.xxx 222.165.130.xxx 66.163.169.xxx ISP (Sri Lanka) User 8 National Server (Sri Lanka) 202.69.200.xxx

  9. Results on uploaded to www.broadbandasia.info

  10. Methodology depends on a hybrid of Volunteer Computing to get sufficient data Uses computer processing and storage resources of the general public (volunteers) for computationally intensive projects (Anderson, 2009)

  11. Users in USA get more value for money Download from International Domain Download from National Domain

  12. Latency to national level similar but diverges at International level * Limits specified by the Singapore Regulator IDA for national and International network latency 300 ms* 85 ms*

  13. Does the model Work? Methodology has potential – but adoption levels need to be improved. Number of volunteers lower than expected Many register/download software; but few complete Possible ways to increase adoption: More publicity (More volunteers from Sri Lanka and India where awareness work (workshops, public lectures) was done Incentives (free software for highest number of readings contributed etc) Seeing positive results (through operator and policy makers taking actions based on results)
