2. Vitina, 13-14 March, 2008 2RURAL WINGS IP Network usage & reliability monitoring system  Network activity monitored at hub level using SSPs monitoring tools.  Key achievement of RP2: implementation and validation (through the First Test Run periods) of a homogeneous Network Usage monitoring system and procedures for the 3 RW SSPs (Avanti, Hellas Sat and TTSA) coordinated by Astrium.  Steps:  Metrics identification  Graphs definition  Procedures and deadlines  Platform implementation / adaptation  First Analysis of results  Recommendations for next periods

3. Vitina, 13-14 March, 2008 3RURAL WINGS IP Metrics identification  Network usage metrics: In & Out (typical Internet traffic asymmetry)  Traffic volume: total consumed bandwidth  Applications & Protocols: volume distribution between different applications  Data rate: instant measure of the throughput  System reliability indicators:  Time evolution of anomalies  Mechanism of incidents notification  Concerned network segment and equipment  Type of incident  Solution applied  Intervention  Resolution time

4. Vitina, 13-14 March, 2008 4RURAL WINGS IP Graphs definition (1/2)  Raw data collected continuously  Simple treatment to obtain synthesis graphs and charts  Network usage graphs (Monthly basis)  1A Traffic volume per site  2A Global traffic volume per month  3A Detailed IN traffic volume per month  4A Detailed OUT traffic volume per month  5A Inbound Protocols distribution per site  6A Outbound Protocols distribution per site  7A Inbound protocol distribution per month  8A Outbound protocol distribution per month  9A Average IN Data rate per site and per month  10A Average OUT Data rate per site and per month  11A Histogram of sites average data rate

9. Vitina, 13-14 March, 2008 9RURAL WINGS IP Avanti Traffic Monitoring Platform  Main tool: Allot NetEnforcer/NetXplorer  Bandwidth management: rules  Network performance statistics: dedicated software, export to statistical package  Most common statistics: BW, hosts, pipes, protocols  Raw data: .csv  Macros  Pivot tables  Agreed format

10. Vitina, 13-14 March, 2008 10RURAL WINGS IP TTSA Traffic Monitoring Platform  Main tool: Allot NetEnforcer(Turin Hub)/NetXplorer(Secure Hosting Platform in Paris)  Architecture  Traffic curves made available to users (NCs) via MedSky client application.

11. Vitina, 13-14 March, 2008 11RURAL WINGS IP Hellas Sat Traffic Monitoring Platform  Main tool: Packeteer Packet Shaper 1700  Max BW: 45 Mbps  Configuration:  In & Out traffic detection  1 group per RW Pilot site based on IP addressing detection  Raw data: .csv files directly stored to database connected to Packeteer device

12. Vitina, 13-14 March, 2008 12RURAL WINGS IP First Test Run results – Traffic volume  Monitored period: Dec 07–Jan 08  Increase in the RW Pilot sites activity  RW usages evolving and Internet access usage increasing  Download (In) >> Upload (Out)  Top sites per SSPs: Dezna (TTSA) – 80.3 GB/362.5 GB Cilcennin (Avanti) – 25.9 GB/3.2 GB Parakentro (Hellas Sat) – 13.3 GB / 0.4 GB (Janv08)

13. Vitina, 13-14 March, 2008 13RURAL WINGS IP First Test Run results – Protocols  « All other » category: protocols not included in previous categories. Usually corresponds to P2P  Important presence of « All other » category in RW pilot sites.  P2P control policy implemented?  TTSA included QoS rule for this type of protocols in Dec, decrease in P2P volume detected in Jan.  Important volume of http:  Intensive web browsing  http downloads  P2P using port 80  To be followed closely

14. Vitina, 13-14 March, 2008 14RURAL WINGS IP First Test Run results - Anomalies  Registered Anomalies:  Avanti (Dec 07- Jan08): 7  Hellas Sat (Dec06-Jan 08): 9  TTSA: 0 (?)  Notified through SSPs Help Desk  Avanti: hub platform migration  Sat modem distant reconfiguration required (< 1 day)  Hellas Sat:  ODU on site intervention (5-10 days)  Sat modem remote reconfiguration (< 1 day)

15. Vitina, 13-14 March, 2008 15RURAL WINGS IP Recommendations and Next Steps  RW Monitoring platform: validated!  Improvement on throughput statistics to come  P2P activity to be supervised closely by all SSPs  RW Pilot Sites Maintenance procedures crucial for successful site operation  R oles to be clarified for SSPs, NCs & end-users  Anomaly report to be used also by NCs?  For next periods:  Correlation with the number of end-users per site required (1 user = 1 PC)  Further correlation with NCs and end-user system experience
