Abstract
In one embodiment, a device receives connected phase data from a neighboring device indicative of one or more electrical phases to which the neighboring device is connected. A determination is made, based on the connected phase data for the neighboring device, whether to transmit the message to the neighboring device over a single electrical phase at a higher output power or over a plurality of electrical phases at a lower output power. The message is then transmitted to the neighboring device over the determined one or more electrical phases.
Claims19
A method comprising:
- receiving, at a device, connected phase data from a neighboring device indicative of one or more electrical phases to which the neighboring device is connected;
- updating, at the device, a stored neighbor table with the connected phase data received from the neighboring device;
- determining, using the stored neighbor table stored on the device, whether to transmit a message to the neighboring device over a single electrical phase at a higher output power or over a plurality of electrical phases at a lower output power;
- and
- transmitting the message to the neighboring device over the determined one or more electrical phases.
An apparatus comprising:
- one or more network interfaces configured to communicate in a power line network;
- a processor configured to execute one or more processes;
- and
- a memory configured to store a process executable by the processor, the process when executed operable to:
- receive connected phase data from a neighboring device indicative of one or more electrical phases to which the neighboring device is connected;
- update a stored neighbor table with the connected phase data received from the neighboring device;
- determine, using the stored neighbor table, whether to transmit a message to the neighboring device over a single electrical phase at a higher output power or over a plurality of electrical phases at a lower output power;
- and
- transmit the message to the neighboring device over the determined one or more electrical phases.
A tangible, non-transitory, computer-readable media having software encoded thereon, the software, when executed by a processor, operable to:
- receive connected phase data from a neighboring device indicative of one or more electrical phases to which the neighboring device is connected;
- update a stored neighbor table with the connected phase data received from the neighboring device:
- determine, using the stored neighbor table, whether to transmit a message to the neighboring device over a single electrical phase at a higher output power or over a plurality of electrical phases at a lower output power;
- and
- transmit the message to the neighboring device over the determined one or more electrical phases.
