"End-to-end" could, for instance, incorporate home and enterprise networks, and the impact of peering, caching and Content Delivery Networks (CDNs). > > > >>> - 3.1, 1st para: > >>> > >>> Can you provide a definition or reference for "mean opinion score"? > >> > >> Not addressed. > > > > If a reference is really needed, then i guess > http://en.wikipedia.org/wiki/Mean_opinion_score will do. > > > > On a quick search, it looks like that's at least discussed (and maybe > defined) in ITU-T P.800. > > http://www.itu.int/rec/T-REC-P.800-199608-I/en I'll add whichever reference you prefer - wiki or P.800 which is specifically about telephony.

"Probe" has many meanings. Context might be enough for some > readers, but possibly not all. In S3.1 probe is first mentioned. So then I'll add this text:- NEW (A probe is a device or piece of software that makes measurements and reports the results, under the control of the measurement system. Implementation options are discussed in Section 5.) And in S5 OLD One way involves a special hardware device that is connected directly to the home gateway. ... Another approach involves implementing the measurement capability as a webpage or an "app" that end users are encouraged to download onto their mobile phone or computing device.
