A system for communicating between Radio Access nodes includes a Radio Access Network (RAN) comprising a plurality of Radio Access nodes and a backhaul system interconnecting the Radio Access nodes. The backhaul system identifies at least some paths belonging to the backhaul system, each path interconnecting a pair of Radio Access nodes belonging to the RAN. The backhaul system ascertains, per path, at least one type of Traffic Engineering (TE) metric associated with transporting data between a pair of Radio Access nodes, and convey, per path, the TE metric, to the pair of Radio Access nodes. Optionally, the pair of Radio Access nodes perform a real-time data exchange, provided that the TE metric, conveyed to one of the Radio Access node of the pair, indicates that such an exchange is viable using the path. Optionally, at least some of the paths comprise wireless data links.
