Bandwidth is the capacity available to receive and send data over a certain network connection.

There are a few important concepts around bandwidth:

  • Available bandwidth fluctuates dynamically over time
  • Sending (outgoing) and receiving (incoming) bandwidth are asymmetric in nature
  • In VoIP and WebRTC, our purpose is to estimate the available bandwidth in as much accuracy as possible – the better the estimate, the better the media quality are be able to provide
  • The estimation we make derives the maximum bitrate that we can send or receive
