Instead, it’s an umbrella term that encompasses a wide range of mechanisms used to control traffic patterns on the network. QoS has already proven to be the go-to technology for converging voice, video and data networks. But as business needs change, so do demands for QoS technologies. This paper will cover the basics of QoS, its needs, and a few types of available QoS mechanisms.
