IEEE802.1 AND Q S
P O
The DGS-1008TL Switches support 802.1p priority queuing
Quality of Service. The implementation of QoS (Quality of Service)
and benefits of using 802.1p priority queuing are described here.

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 bandwidth can be saved. The Switch has separate
hardware queues on every physical port to which packets from
various applications are mapped to and assigned a priority. The
illustration below shows how 802.1P priority queuing is
implemented on the Switch. The eight IEEE 802.1P priority levels
defined by the standard are mapped to the two class queues used in
the Switch.
2 Priority Queues
Queues:
Class-0 Class-1
0 1 2 3 4 5 6 7
Priority:
