Methods are disclosed for forming a network (1) of nodes (A-H) from a plurality of nodes (A-H) and a plurality of potential transmission links (2) between respective nodes (A-H). Methods are also disclosed for adapting an initial mesh communications network configuration to a final mesh communications network communications configuration. Methods are also disclosed such that at least some of the changes to the initial mesh communications network configuration that are required as part of the adaptation to the final mesh communications network configuration form a group of changes such that all of the changes within the group can occur substantially simultaneously. Various other methods useful in or to a mesh communications network (1) are also disclosed herein.
