Network Information
This screen presents a list of all devices on the PowerLine network. Devices that are active on the current logical network will show a transfer rate and receiver rate.
QoS
Quality of Service (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 eight levels (0 – 7) of user priority.
The PowerLine HD Ethernet Adapter allows four levels (0 – 3) of Channel Access Priority (CAP). Therefore, the eight levels of VLAN Ethernet tags must be mapped to the four 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 music; while CAP 1 and CAP 0 are used for data. Mapping VLAN tags or ToS bits to CAP levels is easily done using the VLAN Priority Mapping function on the QoS tab window.
