Multiple topology routing architecture in computer networks

摘要

In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

1. A method, comprising:
in a low power and lossy network (LLN) comprising a plurality of devices, creating a first routing topology, wherein the first routing topology maps one or more receiver devices that can receive transmissions from a sender device using a first type of channel; creating a second routing topology, wherein the second routing topology maps one or more receiver devices that can receive transmissions from a sender device using a second type of channel; and generating a first broadcast schedule for the first routing topology and a second broadcast schedule for the second routing topology.
