Device for shared management of a resource between several users

Device for shared management of a resource (1) between several users, of the type comprising:

• a work memory (3), able to store user identifiers (ui), as well as several share parameters (Di), and several amounts (Ei) capable of advancing,
• a decision means (6) for allocating a chosen service slice (Qi) of the resource to a user selected(uS) as possessing the least advanced amount (Ei), and for subsequently advancing the amount (Ei) of this selected user (uS) according to a chosen increment (dEi),
• a memory link means (5), for associating a share parameter (Di) and an amount (Ei) with each user identifier (ui), while defining user queues of the “first in-first out” (FIFO) type, such that the identifier at the head of a queue always designates the user having the least advanced amount (Ei) in this queue,
• characterized in that the work memory (3) is able to store in addition a limited number of values of increments (P(c)), in that the memory link means (5) is contrived, on the one hand, so as to associate one of these values of increments (P(c)) with each user, and, on the other hand, to define the said queues on the basis of the said values of increments (P(c)) in limited number, and in that the decision means allocates the selected user (uS) a service slice (Q(uS)) associated with a pair (D(uS)), P(c)) represented by its share parameter (D(uS)) and the increment of its queue (P(c)), according to a predetermined law.
