FIELD: physics, communications.
SUBSTANCE: invention relates to prevention of a transient loop in a packet switched communication network. The method comprises the following steps: receiving a message at a network interface which contains information on a change in topology of the network; blocking forwarding of traffic to each neighbouring node of the network at the network interface by a processing unit; agreeing by the processing unit on the topology with each neighbouring node by exchanging description of the topology database or digest of the topology database; and unblocking the forwarding of traffic when the neighbouring node has information about the topology which is the same as the information about the topology stored in memory.
EFFECT: preventing the onset of all possible loops, which could emerge during a transient process in a network.
