TL-PA101 85Mbps Powerline Ethernet Adapter 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'. Powerline 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-and must while CAP 1 can CAP 0 are used for data. Mapping VLAN tags to CAP levels is easily done using the VLAM Priority Mapping function on the QoS tab window. Simple Application Mapping: The group allows you to choose the type of traffic you will use your local HomePlug device for by pitching on one of the following four radios. Please select the radio type according to your demand. Advanced VLAN Priority Mapping: The group sets VLAN priority to CAP mapping and default priority.Note that in HomePlug, CAP 3 is the highest priority while CAP 0 is the lowest priority. The values shown in VLAN Tags Priority are the default settings for the first running.

85Mbps Powerline Ethernet Adapter
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’. Powerline 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-and must while CAP 1
can CAP 0 are used for data. Mapping VLAN tags to CAP levels is easily done using the VLAM Priority
Mapping function on the QoS tab window.
Simple Application Mapping:

Advanced VLAN Priority Mapping:
