Abstract

See full text

In one embodiment, one or more routing update parameters may be set for and propagated to nodes of a directed acyclic graph (DAG) in a computer network, the routing update parameters indicative of when to perform a corresponding routing update operation. A decision node (e.g., a root node of the DAG, application in a head-end, etc.) may gather network statistics of the DAG during operation based on the routing update parameters, and may accordingly determine at least one adjusted routing update parameter based on the gathered network statistics. This adjusted routing update parameter may then be propagated to the nodes of the DAG, such that the nodes operate according to the (adaptively) adjusted routing update parameter.
