Abstract: A node for a packet-address-switched or label-switched communication network comprises i) signaling means responsible for exchanging signaling messages with other nodes of the network in order to reserve resources of connecting paths each associated with a connection identifier and beginning at the node, and ii) control means responsible for, on the one hand, forming intervals of use of connecting paths to be set up between the node and at least one output node and, on the other hand, for commanding the signaling means to transmit to nodes that will have to participate in each of the connecting paths to be set up signaling messages containing connection identifiers of the connecting paths in which they have to participate and programming data representing their respective intervals of use and requesting them to prereserve resources at the level of their control plane necessary for setting up the connecting paths during time ranges that are a function of the intervals of use.
