What is QoS (Quality of Service)?
QoS is a measure of the quality and low latency (delay) of the video and audio connections. Connecting H.323 video conferences over the commodity Internet are always considered “best effort”. Even with enough allocated bandwidth between your endpoint and the other site, you are competing for the same bandwidth that all the other data traffic on the Internet. with nothing to prioritize the traffic. Multiple router “hops” can cause latency and jitter making successful video conferencing not always possible.
