CARNET meter

CARNET Bandwidth Meter is a meter that allows users of the CARNET network to measure the data transfer rate to and from the CARNET network.

The results of data transfer rate measurement vary depending on:

  • the number of users who use the network at the same time
  • the type of user access network
  • the load of the user’s computer
  • the load of CARNET servers, etc.

The measurement results also depend on the internet browser that is used. CARNET’s recommendation is to use the Mozilla Firefox browser.

Measured values shall always be slightly lower than the nominal values published by user’s Internet access providers, since the meter measures only user useful data, but not protocol add-ons.

CARNET Bandwidth Meter is for personal use only and cannot be used for other purposes. CARNET reserves the right to restrict access to users of commercial internet access service providers.
