[e2e] Losses unrelated to congestion on wired networks

just got some.
To one of port monitored ( Cisco4006, 10/100Mbps
interface working at 10Mbps full duplex),
in past 7 days we have the following statistics:
Port Bandwidth utilization:
Max Recv bit rate: 159075.33bps
Min Recv bit rate: 3563.3bps
Max Trans Bit rate: 3971732.25bps
Min Trans Bit rate: 543255bps
Packet loss rate:
as the measurement is still going on, we have not do
more analysis on those raw data. Also, the above
measurement is based on RTT measurement every 20sec
by fping 20 packets to remote end from measurement
station. The packet size we use is 56bytes. To current
situation, the packet loss rate from measurement
station to access router is kept to 0%.

|<----------- RTT ---------------------->|
Anyway, we are trying to modify our software to
meausure directly from access router.
