Abstract: A method performed by a first node. The first node operates in a communications network. The first node determines, based on a header of a packet, a first number of hops. The first number of hops are the hops the packet has to traverse in the communications network to reach a second node in the communications network. The header of the packet indicates a second number of hops between the second node and a third node in the communications network in a first path. The first node obtains a wired backhaul connection to a core network of the communications network from the third node. The first node then initiates routing the packet towards the second node based on the determined first number of hops.
