The invention relates to a method for mesh-wide capacity management in a mesh network (1), in particular comprising mesh links (2a, 2b) of different link technologies/with different local properties, the method comprising: signalling from at least one link resource manager associated with a mesh link (2a, 2b) or a group (3) of mesh links of the mesh network (1) to at least one network capacity manager (5) information about a calculation model to be applied for calculating at least one flow performance characteristics, in particular a resource consumption, for establishing at least one packet-based traffic flow on the mesh link (2a, 2b) or on the group (3) of mesh links. The invention also relates to a link resource manager, to a network capacity manager (5), to a signaling system, and to a mesh network (1).
