The invention relates to a method for controlling a network element with a plurality of communication ports for transmitting and receiving data packets to and from other network elements in a network, wherein a spanning tree topology model of at least a subset of the network is stored in at least one database in the network element. The method comprises the steps of:-detecting an event indicating a change in the topology of the network; updating the spanning tree topology model of the subset of the network based on information derived from the topology change event, said subset including the network element, the origin of the topology change event and the network elements that are affected by the topology change, and-determining if the network element is operating as a topology handler for the detected event. If the network element is operating as a topology handler, a new spanning tree topology model is calculated based on the model resulting from the updating step, and a topology change command (TCC), including information about the new spanning tree topology model, is transmitted to the network. The invention provides an efficient reconfiguration of the network topology in the case of a topology change event. |
