QoS
Quality of Service (QoS) requirements are different for various data
types, such as streaming video or music, voice and raw data. To provide
higher QoS for streaming data, priority levels can be set using tags at
the beginning of data frames. Virtual Local Area Network (VLAN) 802.1p
priority tags on Ethernet frames are used to specify eight levels (0 – 7)
of user priority.
The PowerLine HD Ethernet Adapter allows four levels (0 – 3) of
Channel Access Priority (CAP). Therefore, the eight levels of VLAN
Ethernet tags must be mapped to the four levels of CAP priority, where
CAP 3 is the highest priority and CAP 0 is the lowest. CAP 3 priority
might be used for voice and network management frames; CAP 2 is
used for streaming video and music; while CAP 1 and CAP 0 are used
for data. Mapping VLAN tags or ToS bits to CAP levels is easily done
using the VLAN Priority Mapping function on the QoS tab window.
