Installing the Powerline HD Ethernet Adapter 2-17
v1.1, November 2006
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 (Tranmission Control
Protocol) is used for data transfer. The easiest way to give priority to multimedia traffic, is to
assign high priority to UDP transfers. To give priority to database applications, assign high priority
to TCP transfers.
To set the priority of data transfers by the type of protocol:
1. Start the HDX101 Configuration Utility from the PC and wait for the utility to detect the
Powerline HD Ethernet adapters connected to the computer.
2. For each device where “No” is displayed in the Configured column, click the device name to
select it, and then click the Configure button.
3. When the Configured column indicates “Yes” for all detected devices, select the QoS (Quality
of Service) tab.
4. In the “Advanced QoS Options” section. To give priority to multimedia transfers, select UDP
priority and UDP high priority in the Rule list boxes.
Otherwise, to give priority to database or document transfers, select TCP priority and TCP
high priority in the Rule list boxes.
