4.5.2 VLAN Parameter
Quality of service is particularly important for the transport of traffic with special
requirements. In particular, much technology has been developed to allow computer
networks to become as useful as telephone networks for audio conversations, as well
as supporting new applications with even stricter service demands.
1) 802.1Q
The IEEE 802.1Q standards define architecture , services , protocols and algorithms for
Virtual Bridged LANs.
No Quality of Service mechanisms are defined in this standard, but an important
requirement for providing QoS in this standard, e.g. ability to regenerate user priority of
received frames using priority information contained in the frame and the User Priority
Regeneration Table for the reception Port.
2) 802.1p
IEEE 802.1p standards, Traffic class expediting and dynamic multicast filtering:
It describes important methods for providing QoS at MAC level. IEEE 802.1p is very
effective. Packets will be sent according to the priority level. IEEE 802.1p describes no
