* Use Seque in ops queue.
Standardizing some uses
- Change OpsQueue to use Deque so that it can grow/shrink as necessary and
need not worry about channel getting full and dropping events.
- Change StreamAllocator and TelemetryService to use OpsQueue so that
they also need not worry about channel size and overflows.
* Address feedback
* delete obvious comment
* clean up
* Participant traffic load.
Capturing information about participant traffic
- Upstream/Downstream
- Audio/Video/Data
- Packets/Bytes
This captures a notion of how much traffic load a participant is
generating.
Can be used to make allocation decisions.
* Clean up
* SIP patches
* reporter goroutine
* unlock
* move traffic stats from protocol
* check type
* Use a worker to report signal/data stats.
Was checking if reporting is needed on every update.
The check is wasted work if volume of signal/data messages is high
as reporting happens only once in 10 seconds.
Changing to a worker based on a timer. And also aligning with
telemetry reporting interval which defaults to 30 seconds.
* Remove unused constant
Because we aren't able to get CPU count/load info on Windows, they are
stubbed out to return placeholders. This restores compatibility to run
on Windows.
* send min/median connection score along with avg
* guard against divide by zero for avg score calculation
* update median calculation

UpdateSubscription had a shortcoming where when it couldn't find the
participant, it ignored the request.
This PR further removes the reliance of current publisher state from
subscribers.
- SubscribeToTrack only takes in a trackID
- Introduced RoomTrackManager to maintain all published tracks to a room
- Added TrackUnpublished event to clearly indicate when a track has been removed
- SubscribeRequested event no longer include information about the publisher
Sometimes the initial selected node could fail. In that case, we'll give it a few more attempts to locate a media node for the session instead of failing it after the first try.
Added a new manager to handle all subscription needs. Implemented using reconciler pattern. The goals are:
improve subscription resilience by separating desired state and current state
reduce complexity of synchronous processing
better detect failures with the ability to trigger full reconnect
* add prometheus stats for rtt/jitter/packet loss
* add track source to metrics
* better packet loss bins
* add track type to metrics
* remove source from AnalyticsStat
* regenerate telemetry service fake
* compute loss from per stream packet count
Related to livekit/protocol#273
This PR adds:
- ParticipantResumed - for when ICE restart or migration had occurred
- TrackPublishRequested - when we initiate a publication
- TrackSubscribeRequested - when we initiate a subscription
- TrackMuted - publisher muted track
- TrackUnmuted - publisher unmuted track
- TrackPublish/TrackSubcribe events will indicate when those actions have been successful, to differentiate.
* initial commit
* add correct label
* clean up
* more cleanup on adding stats
* cleanup
* move things to pub and sub monitors, ensure stats are correctly updated
* fix merge conflict
* Fix panic on MacOS (#1296)
* fixing last feedback
