<DIV><FONT face=宋体 size=2>Hi Craig,</FONT></DIV>
<DIV><FONT face=宋体 size=2></FONT> </DIV>
<DIV><FONT face=宋体 size=2>We have got some flows metrics on an aggregative link
of a carrier's MAN with NetTurbo which is a network monitoring system developed
by ourselves. If these data are useful for you, we will send
more data to you including rate of flows new-adding, rate of flows close,
workload of flows. </FONT></DIV>
