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 RURAL WINGS IPVitina, 13-14 March, 2008

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

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

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 Roles 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
