What is Guaranteed Quality of Service (QoS)?
Guaranteed QoS is a necessity for deploying new services such as broadcast quality IPTV. “Real time” data such as this is often streamed to a customer’s home for display on a TV screen without interruption. Unlike computer data, the nature of the real time data does not allow it to be re-transmitted if it is in error. It must also arrive at the display device when it is required to avoid glitches on the screen. With Guaranteed QoS, data is sent to the client with a predetermined error rate, jitter and latency.
