This invention relates to a method and system for the discovery of suitable AAP nodes to provide bonding functionality in an operator network. The presented solution uses multicast AAP discovery messages send by the bonding client for the discovery of AAP-Nodes in the operator network. These AAP discovery messages are send by the bonding client over all available links which are intended to be used for bonding. The AAP-Nodes within the network will receive a multitude of the AAP discovery messages from the same bonding client. Upon this event the AAP-Nodes will reply using an AAP reply message. The bonding client will receive a multitude of AAP reply messages and will be able to reconstruct the logical network topology, in particular the location of cross over nodes, based on the information contained in the multitude of AAP reply messages.
