question on draft-ietf-tewg-measure-04.txt

[Jing Shen <jshen@cad.zju.edu.cn>]

Hi,


in sec10.1, there is a "Delay Variation" measured at Interface, 
to my understanding IPDV is a type of measurement at e2e level or link
level. Why does the draft propose that? and how to measure it?

I'm not clear what's the relationship between "throughput" and "goodput"
used in the draft. If they all refer to the amount  of traffic
successfully
delivered,  do we need to measure network traffic sent by source nodes?


And, what about the measurement precision? I means should the accuracy
of measurement be discussed? 



regards
