networ>, an * rame arrives at the receiver earlier than service pac>ets in the measurement period. As a result, some
pac>ets are not measured or more pac>ets are measured.
"% %* v2 uses the coloring D window detection solution. The time when an * rame is received is not used as the time
when pac>et measurement ends.
The preceding igure shows the principles o the solution! The sender divides "% pac>ets into two types 8the * rame isused to delimit the "% pac>ets9 and color the two types o pac>ets! all pac>ets in the previous rame are in Cyc A and all
pac>ets in the later rame are in Cyc +. The characteristics o the two rames rotate. The receiver measures data )ased on
"% path "' and Cyc "'. "n Cyc A, the receiver only measures the data that meets the condition o "% path "' and Cyc A@ in
Cyc +, the receiver only measures the data that meet the condition o "% path "' and Cyc +. "n the overlap area o the two
measurement windows, the overlap time should )e greater than the possi)le networ> out=o=order value.
