hi,
is there any work or research on measuring method
for subscriber (customer)side feelings of network
service?
It seems that e2e ping delay, packet loss may miss
some important factor when we consider subscriber's
feelings.

Although zero packet loss is a sign of very low jitter, you can't
generalize that if there is packet loss. Since jitter is important to
VoIP and some media streaming, you might want to measure that directly.
Of course, if your ping delay measurement is fine-grained enough, then
you can calculate the jitter based on the difference between the maximum
e2e ping delay and the minimum over a period of time. It's better if
the period of time is short enough so that you can learn what your most
likely jitter vaues are, not just the worst case.

We have been doing a lot of work on how to measure the subscriber
"experience" of a network. e2e ping delay actually is quite a good
measure so long as you use it correctly. However we found that using
tools such as iperf to take periodic measurments of TCP throughput, UDP
throughput and packet loss was far more interesting.

You might also find this OWAMP (One Way Active Measurement Protocol)
AKA "One Way Ping" implementation to be quite useful for that sort of
thing.
