8.4 HomePlug AV QoS
Your PLA450 can send different kinds of traffic through your powerline network at different
speeds depending on the priority you give it. This feature is called Quality of Service (QoS).
• You can configure your PLA450 to give priority to powerline network traffic depending
on its destination ( MAC Address or IP Port Number Priority ).
• You can also map the priority settings (VLAN or ToS priority settings) of traffic from
outside your powerline network to priority settings for your powerline network ( Priority
Mapping ).
• Priority can also be assigned according to traffic type such as IGMP ( Default Priority ).
Powerline traffic priority can be set at Highest , High , Mid and Low . The following priority
settings are guidelines. The requirements of your powerline network may differ.
8.4.1 QoS Based on IP or MAC Address
You can prioritize traffic passing through your PLA450 based on the device it is intended for.
Do this by setting the MAC address or IP address of a device(s) on your network and the level
of priority of network traffic going to that device.
For example, if you have a digital media adapter such as the DMA-1100P on your network set
up to play movie files on your T.V., you can set this device to
High . This is because if video or
music traffic is delivered too slowly, quality problems may occur.
8.4.2 Mapping other QoS Priority Settings to HomePlug AV QoS
Wired networks use QoS priority settings such as VLAN priority settings or ToS (Type of
Service) settings to help network traffic flow more smoothly. However, powerline devices
cannot use these priority settings unless they are mapped over to HomePlug AV QoS priority
settings.
(VLAN priority settings are not to be confused with VLAN ID. The VLAN tag contains both
priority settings (0~7) and ID information (1~4095).)
DAK Password The DAK Password (DAK stands for Device Access Key), is used to verify that
