Claim:
A method for sharing a quantity of resources Q total between several users in a telecommunication network or a computing system, starting from a given date, said method comprising an updating of a tree, wherein each node of the tree represents a time period, the tree containing at least one node representing a time period that includes the given date, each node being a parent node of a set of daughter nodes representing a portion of a time period of the parent node a concatenation of the time periods represented by a daughter node being equal to the time period represented by the parent node, the updating of the tree includes, to record a reservation period P of a quantity Q r of resources by a user in the tree, a step of adding nodes to the tree in such a way that a root node of the tree includes a start date of the reservation period P, and said method further comprises a step of adding nodes to the tree including adding all minimum nodes of the reservation period P, a node being a minimum node of the reservation period P if: when the reservation period P is a non-permanent period with an end date, said minimum node represents a time period included within the reservation period P and the parent node of said minimum node represents a time period not entirely included within the reservation period P; and when the reservation period P is a permanent period with no end date, said minimum node represents a time period included within the reservation period P going from the start date of the reservation period P up to the end of the time period represented by the root node of the tree.
