Path diversity with poly-phase links in a power line communication network

摘要

In one embodiment, a node in a network receives communication channel data regarding one or more communication channels available between a particular device in the network and a neighboring device. Each communication channel corresponds to one or more electrical phases over which the particular device can communicate with the neighboring device. The node also receives crosstalk data regarding an amount of crosstalk between the electrical phases over which the particular device can communicate with the neighboring device. The node then generates a routing path for the network based on the received crosstalk and communication channel data.

1. A method comprising:
receiving, at a path computation engine in a network, communication channel data regarding one or more communication channels available between a particular device in the network and a neighboring device, wherein each communication channel comprises one or more electrical phases over which the particular device can communicate with the neighboring device, and wherein the communication channel data comprises a count of single-phase channels, a count of dual-phase channels, and a count of tri-phase channels between the particular device and the neighboring device; receiving, at the path computation engine, crosstalk data regarding an amount of crosstalk between the electrical phases over which the particular device can communicate with the neighboring device; and generating, by the path computation engine, a routing path in the network based on the received crosstalk and communication channel data.
