HDX111 Powerline HD Plus Ethernet Adapter User Manual
2-12 HDX111 Configuration Utility
v1.1, March 2008
The Powerline HD Ethernet adapter offers the following QoS rule options:
• No prioritization. Do not use QoS prioritization.
• UDP priority. Give priority to multimedia applications.
• TCP priority. Give priority to database or document transfers.
• 802.1p prioritization. For QoS-configured business networks prioritize bits in Layer-2
frames.
• TOS or DSCP. For QoS-configured business networks, use prioritization bits in Layer-3 IP
packets. DSCP (Differential Services Code Point) values range from 0 to 63; the
deprecated TOS (Type Of Service) values range from 0 to 7.
3. To make a change, select a rule, and set the priority in the Rule fields. Click Apply so that your
changes take effect.
Prioritizing a Specific Application
If you want to prioritize network traffic for a specific application, you must know the source or
destination ports used, in addition to the protocol. If you do not know the protocol and ports used,
use a network protocol analyzer program

to monitor your network traffic while running the
application that you want to prioritize.
To adjust traffic prioritization for smooth playback for the application in the scenario:
1. Start the HDX111 configuration utility from the PC and wait for the utility to detect the
Powerline HD Ethernet adapters connected to the computer.
2. Select the QoS tab.
1. Not included with the HDX111 Powerline HD Plus Ethernet Adapter.
Scenario: A Storage Central SC101 is connected to one Powerline HD Plus Ethernet Adapter
and a PC is connected to another. An HDTV file is stored in the SC101, and Media
Player on the PC is used to play the HDTV file.
While the video file is being played, the PC user copies a large data file from the PC
to the SC101 and from the SC101 to the PC. Without traffic prioritization, video
playback could be delayed or interrupted.
Note: The SC101 uses UDP port 20001 for multimedia data transfers.
