Abstract
Network apparatus includes a plurality of ports for connection to respective links in a packet communication network, the ports having respective port costs assigned thereto. One or more packet processors are configured to transfer data packets between the ports. A controller is configured to select, using a spanning tree protocol responsively to the port costs, one of the ports as a root port, thereby defining a forwarding topology, to receive data with respect to a quality of packet transmission through the ports over the respective links according to the defined topology, and responsively to a change in the packet transmission quality indicated by the received data, to modify a cost of at least one of the ports so as to cause a modification of the forwarding topology by the spanning tree protocol.
