Real Time Media

• Real time applications are best suited for UDP

• • Voice, music, and video in particular
  • Low end-to-end delay is extremely important
  • Small amounts of loss are tolerable
  • • Some loss can be hidden by the codec
  • VoIP, live music, and live video

• Streaming audio and video (RealPlayer, Windows Media Player, etc.) also use UDP

• • Receiver-side buffering hides some delays and jitter
