Claim:
1. A method, comprising: receiving, at a network device, physical layer information from one or more nodes along a communication path in a network, wherein the physical layer information indicates a first set of nodes of the one or more nodes communicate over an radio frequency (RF) connection with respective neighboring nodes, a second set of nodes of the one or more nodes communicate over a power line communication (PLC) connection with respective neighboring nodes; receiving, at the network device, self-interference information from the one or more network nodes regarding at least the communication path traversing a first pair of the second set of nodes, wherein the self-interference information indicates that the first pair of nodes using a first electrical phase for PLC over the communication path interfere with a second pair of nodes, the second pair being traversed by another communication path and using a second electrical phase different than the first phase, due to cross-talk between the first and second electrical phases; identifying, by the network device, one or more packets to be sent along the communication path; and altering, by the network device, a transmission strategy, the altering comprising instructing the first pair of the one or more nodes to communicate the one or more packets over an RF connection instead of a PLC connection based on the identified self-interference and the received physical layer information.
