Selective topology routing for distributed data collection

摘要

In one embodiment, a device, such as a network management server, determines a traffic matrix of a mesh network, where the traffic matrix indicates an amount of traffic per type of traffic transitioning between the mesh network and a global computer network via one or more current root devices. One or more optimized root devices may then be selected for corresponding directed acyclic graphs (DAGs) based on the amount of traffic and type of traffic. As such, a DAG formation request may be transmitted to the selected root devices, carrying a characteristic for a corresponding DAG to form by the respective selected root devices that indicates which one or more types of traffic correspond to the corresponding DAG.

1. A method, comprising:
selecting one or more optimized root devices from a plurality of capable devices in a mesh network for corresponding directed acyclic graphs (DAGs) based on an amount of traffic and type of traffic transitioning via one or more route devices; and transmitting a DAG formation request to the selected one or more optimized root devices, the DAG formation request carrying a characteristic for a corresponding DAG to be formed by the respective selected optimized root devices that indicates which one or more types of traffic correspond to the corresponding DAG.
