HDX111 Powerline HD Plus Ethernet Adapter User Manual
HDX111 Configuration Utility 2-11
v1.1, March 2008
Prioritizing Traffic on the Powerline Network
By default, the Powerline HD Ethernet adapter QoS (Quality of Service) rules give priority to
multimedia network traffic. This is so that multimedia playback is smooth, even if document files
are being transferred over the network.
In general, multimedia applications use UDP (User Datagram Protocol) for data transfer. For such
applications, the on-time arrival of the data is more important than the data itself. If a packet
cannot be transferred in time, it will be dropped. For applications where the integrity of the data
takes precedence over the data timing, such as database applications, TCP (Transmission Control
Protocol) is used for data transfer.
To view or change the QoS rule settings:
1. Start the HDX111 configuration utility from the PC and wait for the utility to detect the
Powerline HD Ethernet adapters on the network.
2. Select the QoS (Quality of Service) tab.
The default settings in the Rule fields are UDP priority and UDP high priority. These
settings give priority to give priority to multimedia transfers.
Note: QoS settings are applied to every detected device shown on the Main tab.
