The third tab window labeled “Advanced” is for Quality of Service. With the proper configuration, the

limit bandwidth can be took full advantage. 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 8 (0~7) levels of “user priority”. Homeplug AV

powerline allows for 4 levels of Channel Access Priority CAP 0-3)). Therefore, the 8 levels of VLAN

Ethernet tags must be mapped to the 4 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 while CAP 1 and CAP 0 are used for data. Mapping VLAN tags to CAP levels is

easily done using the VLAN Priority Mapping function on the QoS tab window.
