I think this can follow similar code path as NetworkConnectionTracker.

+mmenke@

Matt, one question came up. Where should the client-side interface of NQE live (the interface that observes state changes of NQE's service-side interface)? 

Does SystemNetworkContextManager sound right? IOThread globals owns the current in-process NQE (https://cs.chromium.org/chromium/src/chrome/browser/io_thread.cc?rcl=a60c8b678f340df16da050c0f2bc126d3e1255fb&l=780). 

It depends...Are we going to want to expose this to content embedders, or
just to Chrome code?  If it's just for Chrome, adding it to
SystemNetworkContextManager makes sense.  If we care about other content
embedders, we may want to make it owned and accessible through some content
interface, though I'm not at all confident of that.

Or if we only have one or two observers, and don't expect more, we could
even just have them directly listen to the NetworkService.

mmenke and xunjieli: Thanks for the help.

I guess I am not sure how the NQE JavaScript API would work with servicification. The same question applies for NCN NetInfo API which is currently plumbed via //content: https://cs.chromium.org/chromium/src/content/browser/net/browser_online_state_observer.cc?type=cs&q=f:browser.*online.*state&sq=package:chromium&g=0&l=15

If I understand correctly, eventually it has to be updated...right?

Oh, this is passed to the renderer?  I hadn't realized that.  We could proxy information through the BrowserOnlineStateObserver, like we do now, and have two process hopes, but that seems inefficient, so what we really should do is have renderer get a connection on creation.

The general way to get a connection to a global object is through a connector, but I don't know how to set them up, nor if a connector can give a connection to a pre-existing object (Without using globals).

Yes, currently NQE is passed to renderers similar to NCN. Here is the implementation (which is very similar to BrowserOnlineStateObserver): https://cs.chromium.org/chromium/src/content/browser/net/network_quality_observer_impl.cc

However, my understanding is that current implementation of BrowserOnlineStateObserver is not compatible with network servicification since BrowserOnlineStateObserver accesses global NCN directly from browser process. 

So, it seems that client-side interfaces of NCN (and NQE) need to live in //content. Is my understanding correct? If so, is there a good place for them in //content?

Yes, they/d need to be in content/common, since they'll be needed by both the renderer and browser process.  More important, though, is how we plumb the mojo pipes through them, and that I'm not sure of.

Thanks, in that case, I will just follow the NCN servicification path. Once BrowserOnlineStateObserver moves to content/common, I can work on moving the NQE JavaScript plumbing as well.

tbansal@, can you update the latest on this bug?

Re #14: I have started the CL on it, but it got deprioritized. I hope to get back to it next week or so.

hi tbansal@, are you looking into it?

marking it as P1 as we need this for network service canary.

@tbansal: Any updates here?

Working on it. I will send out the CL in next couple of days.

Add an API to Network Quality Estimator that can be called
to force the computed Effective Connection Type value.
This will be used in a subsequent CL.

Add a mojom call to observe network quality change events

Network Quality Estimator (NQE) is a part of Chromium network
stack, and posts notifications about network quality
change events to its registered observers. The current
architecture assumes that network service runs in the
same process as browser.

This CL adds a mojom call for observers to request network
quality change notifications over a mojom interface.
This allows us to provide notifications to the browser
process from the network process.

NetworkQualityTracker class lives in the browser process,
receives notifications from the network process, and in turn notifies
its own registered network quality observers.

commit 8649d8eef08028ba6b4cb2cc864a1073cf5ce731

Reland of NQE servicification of data saver proxy

Use network quality tracker instead of network quality estimator (NQE)
to obtain network quality in data reduction proxy component.

Network quality tracker can provide network service when network
service is enabled as well as when network service is disabled.

data_reduction_proxy_service.h receives network quality
estimates on UI thread from network quality tracker.
On receiving estimates, it posts them to d_r_p_io_data
which lives on IO thread, and consumes the estimates.

PS#2 is the original CL that got reverted.

Thanks!
