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

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

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
