Avanti: Up to 17 deployed sites in June 2009. General increase of activity:
Highest activity peak in July 2009. Evolution of average volume: from average 30 GB consumed in Jan 08 to 60 GB registered at the mid 2009.

1. Traffic volume per month (2/3)
Hellas Sat: Up to 34 deployed sites in October 2008. General increase of activity following deployments:
Evolution of average traffic: 110 GB/month in 2008 against 200 GB/month in 2009.
Since most of the sites are school, traffic is very related to school periods (decrease of volume during holiday periods: summer, Easter)

TTSA: Up to 63 deployed sites in January 2009. General increase of activity following deployments:
Evolution of average traffic: < 25 GB/month in 2008 against > 150 GB/month in 2009.
A lot of sites were schools so here again traffic is very related to school periods (decrease of volume during holiday periods: summer)

3. Inbound (download) protocol per month
« All other » category: protocols not included in previous categories. Usually corresponds to P2P.
Avanti: web browsing is the major usage of the service (70%). P2P traffic has increased during summer traffic peak 2009 P2P monitoring is constant activity. Hellassat: web browsing (40%) and streaming/instant messaging (40%). P2P stabilized around 20% since 08 Stable P2P rules.TTSA: main applications include web browsing (40%) and streaming (30%). P2P volume almost disapeared. Very controlling P2P rules
Other most common protocols: Streaming: DBC server, video on
demand sites Instant Messaging, videoconferencing Mailing

4. Inbound (download) protocol per site (1/3)
Avanti UK sites using larger set of applications. Hungarian sites mainly drown by web browsing and some mailing. Bewholme and Biggar are the responsible for the high P2P activity
registered in summer 2009.
Closely follow high P2P sites

pilot sites Interesting to provide particular QoS for this service. “All others” is present in all sites, more important in less active sites.

5. Throughput evaluation
Throughput is a very particular metric: measured instantaneously and so difficult to analyse average values.
Example: Manso site (sat+wifi:25 users, 3rd top site for TTSA), devoted monitoring tool for throughput.
350 Overall activity in October 2009Average per day.
Zoom on one day from 11 to 12 am.Average per 30 seconds.

Test Run results – Anomalies (1/3)
Registered Anomalies (traced by SSPs Help Desk): 123 anomalies for 116 monitored sites during a total cumulated period of operation of 1790 months
1 anomaly per site every 15 months of operation: very low nb of anomalies
Very important role of the Help Desk and the maintenance procedure in order to ensure the success of the operation.

Typical learning curve for the anomalies: slow begin, peak during deployment peaks and 1 or 2 months later and final reduction in incidents once the deployed solution is mature and users are used to the technology.

Conclusions and lessons learned
17 RURAL WINGS IPBrussels, 18th March, 2010
Conclusions & lessons learned
Complete success of the traffic and reliably methodology defined early in the project: it enabled us to closely follow the pilot sites activities and consequently adapt RUW services.
Global increase of Rural Wings usage observed since 2008. Following pilot sites deployment Maintaining activity during the whole project Full set of applications used (Streaming, File transfer, Instant
messaging…) however the main application is WebBrowsing. QoS rules must follow this network usage.
Keep adapting rules for particular traffic: streaming, http navigation
In general P2P has been controlled Very low incidence of anomalies Crucial role of the Help Desk and the overall maintenance
procedure.

3. Ratio IN/OUT (1/3)
Standard asymmetric usage of the bandwidth
Ratio IN/OUT = Inbound traffic / outbound traffic measure the asymetry of the usage. Explained by applications used :- symetrical applications (videoconference, instant messaging...)- asymetrical application (web browsing, downloads, P2P...)Typical ratio between 5 and 20 ( higher = to be checked)
