Abstract
In one embodiment, a device in a network receives a message from a neighboring device that identifies the electrical phase on which the message was sent. Crosstalk is identified between the device and the neighboring device by determining that the message was received on a different electrical phase than the phase on which the message was sent. One or more distinct communication channels between the device and the neighboring device are identified based on the identified crosstalk with each communication channel including or more electrical phases.
Claims20
A method comprising:
- receiving, at a device in a network, a message from a neighboring device that identifies an electrical phase on which the message was sent;
- identifying crosstalk between the device and the neighboring device by determining that the message was received on a different electrical phase than the phase on which the message was sent;
- and
- identifying one or more distinct communication channels between the device and the neighboring device based on the identified crosstalk, each communication channel comprising one or more electrical phases.
An apparatus comprising:
- one or more network interfaces configured to communicate in a 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 a message from a neighboring device that identifies an electrical phase on which the message was sent;
- identify crosstalk between the device and the neighboring device by determining that the message was received on a different electrical phase than the phase on which the message was sent;
- and
- identify one or more distinct communication channels between the device and the neighboring device based on the identified crosstalk, each communication channel comprising 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 a message from a neighboring device that identifies an electrical phase on which the message was sent;
- identify crosstalk between the device and the neighboring device by determining that the message was received on a different electrical phase than the phase on which the message was sent;
- and
- identify one or more distinct communication channels between the device and the neighboring device based on the identified crosstalk, each communication channel comprising one or more electrical phases.
