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

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

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.

Conclusions and lessons learned


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)

4. Outbound (upload) protocol per month

« All other » category: more present in the upload that in the download More flexibility in the outbound for the P2P and globally less traffic.

Avanti: Cilcennin spam problem in June 2008 under control. High P2P increase in summer 2009.

Hellassat: P2P represents more than the 60% of outbound traffic.

TTSA: same progressive decrease on P2P traffic trend as in the inbound. High mailing activity in May and June 2009.
