Here is an example of the results of a ping flood command on a linux system:
[root@xxx164151 ~]# ping -f -c 10 X.X.160.9
PING X.X.160.9 (X.X.160.9) 56(84) bytes of data.
 
--- X.X.160.9 ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 162ms
rtt min/avg/max/mdev = 0.120/0.341/2.267/0.642 ms, pipe 2, ipg/ewma 18.048/0.770 ms

In these results what does ipg/ewma stand for?

Hi jrblair!

I've found two good reference articles from Wikipedia which go in
depth as to the meaning of these acronyms:

IPG stands for the "Inter-Packet Gap":

http://en.wikipedia.org/wiki/Interpacket_gap

EWMA stands for the "Exponential Weighted Moving Average"

http://en.wikipedia.org/wiki/Moving_average_%28finance%29#Exponential_moving_average

Please do not hesitate to request clarification before rating this
answer, if anything is unclear.

Thank you for a quick answer.  I'm actually ashamed that I didn't
think to look these up through Wikipedia myself.

Thanks for the tip, and glad I could help!
