Dynamic routing metric adjustment

An apparatus, comprising:

• one or more network interfaces;
• a processor coupled to the network interfaces and 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:
• set one or more routing update parameters for a directed acyclic graph (DAG) in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation;
• propagate the routing update parameters to nodes in the DAG;
• gather one or more network statistics of the DAG during operation based on the routing update parameters;
• determine at least one adjusted routing update parameter based on the gathered network statistics in response to gathering the one or more network statistics;
• propagate the adjusted routing update parameter to the nodes in the DAG,
• adjust the routing update parameters to a less-aggressive route update policy when specific nodes are running low on power;
• and
• adjust the route update parameters to a more-aggressive route update policy when the specific nodes have sufficient power.

A tangible, non-transitory, computer-readable media having software encoded thereon, the software when executed by a processor on a device operable to:

• set one or more routing update parameters for a directed acyclic graph (DAG) in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation;
• propagate the routing update parameters to nodes in the DAG;
• gather one or more network statistics of the DAG during operation based on the routing update parameters;
• determine at least one adjusted routing update parameter based on the gathered network statistics in response to gathering the one or more network statistics;
• propagate the adjusted routing update parameter to the nodes in the DAG;
• adjust the routing update parameters to a less-aggressive route update policy when specific nodes are running low on power;
• and
• adjust the routing update parameters to a more-aggressive route update policy when specific nodes have sufficient power.

A method, comprising:

• receiving one or more adjusted routing update parameters for a directed acyclic graph (DAG) at a node in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation;
• configuring operation of the node according to the one or more routing update parameters;
• collecting one or more network statistics during operation of the node based on the routing update parameters;
• in response to collecting the one or more network statistics, transmitting the collected network statistics toward a decision device for the DAG to be used to adjust the routing update parameter;
• receiving an updated adjusted routing update parameter from the decision device;
• adjust the routing update parameters to a less-aggressive route update policy when specific nodes are running low on power;
• and
• adjust the routing update parameters to a more-aggressive route update policy when specific nodes have sufficient power.
