Through what ports does the Glasnost communicate with the measurement server Through TCP port 3001 whilst the measurement is taken on the port of the service chosen by the user Specifically BitTorrent 4662 Gnutela 6346 POP 110 IMAP4 143 HTTP 80 SSH 22 Flash Video 8080 10 Why does the Glasnost measurement take so long up to 8 minutes whilst with the NDT it takes only 30 seconds The two tools serve different purposes The Glasnost needs to carry out multiple tests with different traffic profiles in order to detect possible changes in network behaviour which is why the measurement lasts longer 11 Can I use the Glasnost with WiFi Yes because the important thing is not the measurement in itself but rather the differences between the various measurements Since all the measurements are conducted on the same link in an ideal situation where there is no width restriction they should all give similar values 12 Which factors have a negative effect on measurements conducted with the Glasnost As with the NDT anything which generates traffic during the measurement Firewalls that check traffic high usage on the computer s central server and faults in the network cable can also act as additional negative factors as mentioned in answer no 3 13 How accurate is the evaluation by the Glasnost Whilst under ideal circumstances the measurements reflect the actual connection status there are cases where the width may mistake
