A method of managing a node of a Low power and Lossy Network, LLN, the method comprising: monitoring, by a parent node in a LLN, a routing configuration in the LLN; tracking, by the parent node, a value of a triggering parameter that is used to invoke an address change on one or more child nodes (402, 403) associated with the parent node; accessing, by the parent node, a threshold against which to compare the value of the triggering parameter; comparing, by the parent node, the value of the triggering parameter to the threshold; determining by the parent node, based on results of comparing the value of the triggering parameter to the threshold, that the address change at a child node appearing in the routing configuration is appropriate; and invoking the address change of the child node based on the determination that an address reconfiguration is appropriate by generating an address reconfiguration command, wherein the triggering parameter includes at least two of: a level of processor utilization; a size of a routing table on the parent node based on a frequency at which the one or more child nodes move in a directed acyclic graph, DAG, causing topological reconfiguration; an extent of fragmentation of the routing table on the parent node, wherein the extent is the extent to which the child node has an address that falls outside of a specified range of addresses assigned to the parent node; a frequency of routing reconfiguration commands; a number of child nodes associated with the parent node; wherein invoking the address reconfiguration includes transmitting, by the parent node, a unicast signalling message to the child node, the unicast signalling message including the address reconfiguration command directing the child node to perform the address change. monitoring, by a parent node in a LLN, a routing configuration in the LLN; tracking, by the parent node, a value of a triggering parameter that is used to invoke an address change on one or more child nodes (402, 403) associated with the parent node; accessing, by the parent node, a threshold against which to compare the value of the triggering parameter; comparing, by the parent node, the value of the triggering parameter to the threshold; determining by the parent node, based on results of comparing the value of the triggering parameter to the threshold, that the address change at a child node appearing in the routing configuration is appropriate; and invoking the address change of the child node based on the determination that an address reconfiguration is appropriate by generating an address reconfiguration command, wherein the triggering parameter includes at least two of: a level of processor utilization; a size of a routing table on the parent node based on a frequency at which the one or more child nodes move in a directed acyclic graph, DAG, causing topological reconfiguration; an extent of fragmentation of the routing table on the parent node, wherein the extent is the extent to which the child node has an address that falls outside of a specified range of addresses assigned to the parent node; a frequency of routing reconfiguration commands; a number of child nodes associated with the parent node; wherein invoking the address reconfiguration includes transmitting, by the parent node, a unicast signalling message to the child node, the unicast signalling message including the address reconfiguration command directing the child node to perform the address change. a level of processor utilization; a size of a routing table on the parent node based on a frequency at which the one or more child nodes move in a directed acyclic graph, DAG, causing topological reconfiguration; an extent of fragmentation of the routing table on the parent node, wherein the extent is the extent to which the child node has an address that falls outside of a specified range of addresses assigned to the parent node; a frequency of routing reconfiguration commands; a number of child nodes associated with the parent node; wherein invoking the address reconfiguration includes transmitting, by the parent node, a unicast signalling message to the child node, the unicast signalling message including the address reconfiguration command directing the child node to perform the address change.
