Cichlid visualizing IP packet length distributions over time.
The above graph shows a graph of a bucketed IP packet length distribution. The eight X coordinates represent the eight bucketing ranges that were chosen. The Z axis represents the number of packets seen in that size range for a given time interval. The Y axis is time; as each new distribution is displayed, the old one is shifted one coordinate in the Y direction.
This demonstrates the "client shift" feature of Cichlid. The server is only sending a 1-D vector of values, each a packet length distribution, and the client is shifting the matrix by one (discarding the oldest slice) each time a new slice is received. This cuts bandwidth required to animate the graph by 1/Y_SIZE.
