This document describes how to assess the current network conditions.

When you have a video call on WeChat under poor network conditions (for example, when you are in an elevator), WeChat displays a message indicating the current network quality is poor. This document describes how to use TRTC to implement a similar interaction in your own application.

Call Guide

TRTC provides the onNetworkQuality callback to report the current network quality once every two seconds. It contains two parameters: localQuality and remoteQuality.

• localQuality indicates your current network quality, which has six levels: Excellent, Good, Poor, Bad, VeryBad, and Down.
• remoteQuality is an array indicating the network quality of remote users. In this array, each element represents the network quality of a remote user.

You only need to listen for onNetworkQuality of TRTC and display the corresponding prompt on the UI.

import TRTCCloud, { TRTCQuality } from 'trtc-electron-sdk';
const rtcCloud = new TRTCCloud();
function onNetworkQuality(localQuality, remoteQuality) {
switch(localQuality.quality) {
  case TRTCQuality.TRTCQuality_Unknown:
    console.log('SDK has not yet sensed the current network quality.');
    break;
  case TRTCQuality.TRTCQuality_Excellent:
    console.log('The current network is very good.');
    break;
  case TRTCQuality.TRTCQuality_Good:
    console.log('The current network is good.');
    break;
  case TRTCQuality.TRTCQuality_Poor:
    console.log('The current network quality barely meets the demand.');
    break;
  case TRTCQuality.TRTCQuality_Bad:
    console.log('The current network is poor, and there may be significant freezes and call delays.');
    break;
  case TRTCQuality.TRTCQuality_Vbad:
    console.log('The current network is very poor, the communication quality cannot be guaranteed.');
    break;
  case TRTCQuality.TRTCQuality_Down:
    console.log('The current network does not meet the minimum requirements.');
    break;
  default:
    break;
}
for (let i = 0; i < remoteQuality.length; i++) {
  console.log(`remote user: ${remoteQuality[i].userId}, quality: ${remoteQuality[i].quality}`);
}
}
rtcCloud.on('onNetworkQuality', onNetworkQuality);
