This issue is related to:  http://crbug.com/563644 

Would you say how?  I suspect I should be taking that issue into account in my work, and at the moment I'm not clear as to what the right way to do that is.  Is there a design doc for the work described in  issue 563644 ?

A straw-person argument against the relationship: As I understand devtools throttling, it's increasing latency and limiting bandwidth on a per-request level to whatever the target network is estimated to have.  That doesn't currently affect the choices that are made as to whether or not to dispatch network requests.  Eventually I want to look at how to adaptively throttle based on experienced network bandwidth, and I should make sure that that adaptive throttle includes devtools throttling, but that's work not covered by this bug.

I tagged this to make sure the people working on this issue knew devtools has needs that are related to netstack and throttling and maybe our needs align at certain points.

A quick overview of devtools problems with throttling:
   We are wrapping HTTP factory in browser and throttling the data at the browser level. The problem with this is that we cannot throttle things that are handled on the netstack level like handshakes, WebSockets, RTC, exc.

See: go/devtoolsthrottling (internal doc, use chromium account)

commit 5eb6fbc3c9488ec131081ac9090696af47125ae7
Author: rdsmith <rdsmith@chromium.org>
Date: Fri Oct 21 17:36:08 2016

Add a new priority level, THROTTLED, below IDLE.

THROTTLED is used when the consumer is expecting that low priority
requests will soon be followed by higher priority ones.  It directs the
network stack to reserve resources to handle the coming requests.  In
practice this will mean that only a very small number of THROTTLED requests
may be outstanding at any given time.

Implementation of network level throttler.

NetworkThrottleManager serves throttle objects to consumers (currently
HttpNetworkTransaction) that inform the consumer of their throttled state
and let the throttler track their lifetime.
