Network Traffic

Cambridge JANET traffic raw accounting data information

Each traffic accounting page contains a link to download a CSV version of the data. There is one line for each charging group where the format is:

    group, protocol, Mbytes-in, Mbytes-out

The Mbytes-in and Mbytes-out fields are simply the total traffic (measured in megabytes) incoming to, and outbound from, computers in the charging group. The protocol field is historic and will have a value of 0.

The group numbers are matched to descriptions by the itemdesc.csv file. Each line in that file comprises the group number, the institution group identifier and then the description of the group.
