[re-ECN] Evidence of slow network (WAS Re: Comments on "congestion exposure problem" document)

Hi

I change the subject line , perhaps somebody else on the list can find a
good refernce to strengthen the last sentence in para 1 section 5.1 "The
main effect of this has been that users now routinely see their network
connections running slow in the evenings"

I believe the problem exist and I am not worried about my own comments
but I can imagine that some people may claim that this WG is going to
solve a problem that does not exist. Sorry if I keep nagging but I see a
risk that the BoF discussion may evolve around the question "do we have
a real problem to solve?"

I had a look at the CoNEXT contribution, while it describes the traffic
growth I don't really see any mention about problems with people
experiencing slow networks. I guess it is perhaps difficult to find this
info (operators are not likely to publish this kind of reports
externally). 

One comment to the last version of the doc. Section 5.1, para 1 contains
a reference to a blog. I see the blog text mainly as a discussion around
traffic growth, and not about problems with slow networks, so it would
therefore be better to move the refernce to the sentence before. 

Regards
Ingemar
