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.
