Column explanation:

This graph and the numbers above represent traffic leaving the SWITCHlan network. The output bytes on router interfaces leading to different sites connected to SWITCHlan, as well as to SWITCH's upstream providers and peering partners are counted.

In the above table, the columns labeled 'ETHZ/CSCS/EPFL/PSI', 'UNIs', 'UAS', and 'other' show the amount of data transmitted to the ETHs (including CSCS and PSI), the Universities, the Universities of Applied Sciences and a few other organisations also connected to SWITCHlan.

The column 'SWITCH Servers' shows the amount of data transmitted to the central SWITCH servers located at ETHZ and the University of Lausanne (ie. News Server, SWITCHmirror, SourceForge.net download server, Akamai).

The column 'leaving SWITCHlan' shows the traffic that left the SWITCHlan network towards organizations somewhere else on the Internet via upstream providers and peering partners.
