Packet Lengths

  The range of packet lengths.

  Ranges can be configured in the “Statistics → Stats Tree” section of the Preferences Dialog.

Count
  The number of packets that fall into this range.
Average
  The arithmetic mean of the packet lengths in this range.
Min Val, Max Val
  The minimum and maximum lengths in this range.
Rate (ms)
  The average packets per millisecond for the packets in this range.
Percent
  The percentage of packets in this range, by count.
Burst Rate

  Packet bursts are detected by counting the number of packets in a given time interval and comparing that count to the intervals across a window of time. Statistics for the interval with the maximum number of packets are shown. By default, bursts are detected across 5 millisecond intervals and intervals are compared across 100 millisecond windows.

  These calculations can be adjusted in the “Statistics” section of the Preferences Dialog.

Burst Start
  The start time, in seconds from the beginning of the capture, for the interval with the maximum number of packets.

You can show statistics for a portion of the capture by entering a display filter into the Display filter entry and pressing Apply.
