Hash-based multi-homing

Apparatus for communication, comprising two or more network nodes, for deployment in a communication network serving at least first and second nodes, the two or more nodes comprising multiple communication ports and are arranged to accept an assignment of the ports to serve as member ports of a multi-homing group (MHG), each of the member ports associated with a different, respective alternative communication path between the first and second nodes via the communication network, to accept a frame transmitted from the first node to the second node, the frame having a header comprising header fields, to select a single port from among the member ports over which to forward the frame by applying a hashing function to one or more of the header fields at each of the two or more network nodes, and to forward the frame via the selected port over the respective alternative communication path that is associated with the selected port.
