The xStack DGS-3600 Series supports 802.1p priority queuing Quality of Service. The following section discusses the
implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing.

Advantages of QoS

QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for
important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web
browsing applications, file server applications or video conferencing. Not only can a larger bandwidth be created, but other less
critical traffic can be limited, so excessive bandwidth can be saved. The Switch has separate hardware queues on every physical
port to which packets from various applications can be mapped to, and, in turn prioritized. View the following map to see how the
DGS-3600 Series implements 802.1p priority queuing.
