Re: [aqm] floating a draft charter

Hi Wes,

thanks for writting up the chapter. The text reads really well.

I'm in favor of using AQM and ECN, but when I was asking on the mailing list, 
why ECN is not used, the main answer was it's too complex (that relates to 
AQM) and doesn't give large benefits (as operators focus on low loss rates 
and high utilization only). 

I believe the key to get AQM (and ECN) deployed is a very simple AQM scheme. 
And with simple I don't only mean simple to parametrize (like Codel) but also 
a simple and easy to understand algorithm. E.g. a step function like proposed 
with DCTCP (but higher threshold slightly below the may buffersize) to 
incentive deployment of ECN. Loss-based connections would experienced the 
same DropTail behavior than today, while ECN-enabled connections could 
benefit. If more connection support ECN in future the threshold could be 
lower. That's just a very brief idea (on deployment). 

But my point is, we should not only to standardize more and more AQM 
mechanisms because that's a large research area which maybe even should be 
homed in the IRTF, but we need to find actually deployment strategies. Having 
a working group on AQM will already help to make people aware of the topic 
and maybe think about using AQM. But only standardizing more and more AQM 
queue, might end up in investing a lot of working that no-one will ever use.
