Abstract
In a packet communication network comprising a plurality of nodes connected by respective links according to a routing topology, ordered metrics are respectively associated with links each connecting two nodes together directly. On detection of a modification of the routing topology, at the level of a first node connected by a link to at least one second node, a timer value associated with the second node is determined. Next, the timer is set. Finally, on expiring of this timer, a topology update message is emitted destined for the second node. The timer value is provided by an increasing function taking as parameter the metric associated with said link connecting the first node to the second node, so that the larger the metric, the larger the timer value.
