Fluxoscope is a system used by SWITCH for measurements of our external network traffic. One of its products are graphs which represent, for each external connection, the protocol distribution of traffic over time. The example graph shows the traffic distribution on our connection to UUnet (our main US transit provider) over a period of a week. The "positive" part of the graph shows incoming traffic (what we receive from the US), the "negative" part corresponds to outgoing traffic (what we send them).
