Figure 5

Sample results for the DDoS early warning case study. The illustrative time series plots shown correspond to the WikiLeaks event in November 2010 (top row) and the Japan earthquake in March 2011 (bottom row). For each event, the plot at left is the time series of BGP routing updates (note the large increase in updates triggered by the event). The plot at the right of each row is the time series of the social media data, with the red curve showing blog post volume and the blue curve depicting blog entropy. Note that while post volume is scaled for convenient visualization, the scale for entropy is consistent across plots to allow cross-event comparison.
