PATHCHIRP
-----------
pathchirp = throughput
thrumin = one value indicated in column pathchirp is average of different measured values and thrumin shows minimum of all these values
thruavg = average of all values = pathchirp coloumn
thrumax = maximum throughput 
thrustd = standard deviation of all values
epoch = Time passed since january 1, 1970 in seconds
 
TLAYTCP
-------
Tlaytcp = estimated TCP throughput
Thrumin = minimum of all measured throughput
Thruavg = average of all measured throughput = Tlaytcp
Thrumax  = maximum of all measured throughput
Thrustd = standard deviation of all measured throughput
Rttmin = minimum round trip time
Rttmax = maximum round trip time
Rttavg =average round trip time
Rttstd = round trip time , standard deviation
 
PING
--------
min = Minimum Round trip time
avg = average round trip time
max = maximum round trip time
