checking
Any of the RTCIceTransport s are in the checking state and none of
them are in the failed or disconnected state.
connected
All RTCIceTransport s are in the connected, completed or closed state
and at least one of them is in the connected state.
completed
All RTCIceTransport s are in the completed or closed state and at least
one of them is in the completed state.
checking
The RTCIceTransport has received at least one remote candidate and
is checking candidate pairs and has either not yet found a connection
or consent checks [RFC7675] have failed on all previously successful
candidate pairs. In addition to checking, it may also still be gathering.
5.6. enum RTCIceTransportState
connected
The RTCIceTransport has found a usable connection, but is still
checking other candidate pairs to see if there is a better connection.
It may also still be gathering and/or waiting for additional remote
candidates. If consent checks [RFC7675] fail on the connection in use,
and there are no other successful candidate pairs available, then the
state transitions to "checking" (if there are candidate pairs remaining
to be checked) or "disconnected" (if there are no candidate pairs to
check, but the peer is still gathering and/or waiting for additional
remote candidates).
completed
The RTCIceTransport has finished gathering, received an indication that
there are no more remote candidates, finished checking all candidate
pairs and found a connection. If consent checks [RFC7675] subsequently
fail on all successful candidate pairs, the state transitions to "failed".

TODO
4.4.4 RTCIceConnectionState Enum
failed
Any of the RTCIceTransport s are in the failed state.
disconnected
Any of the RTCIceTransport s are in the disconnected state and none of
them are in the failed state.
closed
The RTCPeerConnection object's [[ isClosed]] slot is true.
5.6. enum RTCIceTransportState
new
The RTCIceTransport is gathering candidates and/or waiting for
remote candidates to be supplied, and has not yet started checking.
failed
The RTCIceTransport has finished gathering, received an indication that
there are no more remote candidates, finished checking all candidate pairs,
and all pairs have either failed connectivity checks or have lost consent.
disconnected
The ICE Agent has determined that connectivity is currently lost for this
RTCIceTransport . This is more aggressive than failed, and may trigger
intermittently (and resolve itself without action) on a flaky network.
The way this state is determined is implementation dependent.
Examples include:
Losing the network interface for the connection in use.
Repeatedly failing to receive a response to STUN requests.
Alternatively, the RTCIceTransport has finished checking all existing
candidates pairs and failed to find a connection (or consent checks
[RFC7675] once successful, have now failed), but it is still gathering
and/or waiting for additional remote candidates.
closed
The RTCIceTransport has shut down and is no longer responding to STUN requests.
