**1. Number of Updates per RIS Peer per 24 hours**

An *update* is either a withdrawal or an announce in BGP. This
measurement also unpacks the BGP message, so that, for example, a
withdrawal message that withdraws 3 prefixes counts as 3 "updates".
The plot is per RIS peer per day, using a color for each RIS peer.
As there are in excess of 150 RIS peers here, the plot has a strong
resemlblence to a Jackson Pollock work. There is also a PDF with a
larger resolution referenced below the image.

**4. Number of Updated Prefixes per RIS Peer per 24 hours**

An *Updated Prefix* is described in one or more announce or withdrawal
messages. The number of BGP events per prefix is not plotted here, but the number
of prefixes updated per peer is shown.

**5. Number of Convergence Events per 24 hours**

A *convergence event* is defined here as a sequence of
updates (withdrawals and announces for the same prefix which have
been received within 130 seconds of each other.
