Abstract: An aircraft turbomachine including a mechanical reduction gear including one sun gear, a ring gear, planet gears which are meshed with the sun gear and the ring gear, each planet gear including a first toothing for meshing with the sun gear, and a second toothing for meshing with the ring gear, the first toothing of each planet gear having a diameter greater than that of the second toothing of the planet gear, and a planet carrier, wherein the sun gear is coupled to a first rotor shaft of the turbomachine, the planet carrier is coupled to a second rotor shaft of the turbomachine, the ring gear is fixed to a stator of the turbomachine.

Abstract: A planet carrier for a speed reducer of an aircraft turbomachine, the planet carrier including a cage carrier and a cage. The cage can have two parts: a first part having a wall and bridges, these bridges projecting axially from a face of this wall and including first axial ends connected to this face and second free axial ends; and a second part having another of the walls, this other wall including a face to which the free ends of the bridges are applied. The two parts of the cage can be attached together by screws.

Abstract: A data packet transmission network comprises a stream of packets of data sent by a first terminal passes in transit through at least one network equipment with which there is associated a stream measurement unit; wherein the first terminal and the measurement unit are connected to a collection unit. The measurement method comprising the following steps: the first terminal sends a specific stream of packets, each having a different determined size, the sizes being such that in a set of r packets, r being a positive integer less than or equal to the number of packets of the stream, there are not any two subsets of the set of r packets comprising the same number of packets and having the same cumulative total size; the measurement unit analyzes at least one packet and at most r packets of the stream passing in transit through the network equipment.

Abstract: The device for access control between ATM networks, comprises signaling analysis means (4) and traffic analysis means (20, 21) linked to an ATM switch (3) configured so as to steer via the signaling analysis means, ATM signaling messages exchanged between internal and external ATM networks, and so as to steer via the traffic analysis means, traffic-bearing ATM cells exchanged between the internal and external networks within the framework of ATM connections established by means of said ATM signaling messages. Access control management means (7) dynamically configure the traffic analysis means (20, 21) as a function of an access control policy and of information gathered by the signaling analysis means (4) in such a way that the traffic analysis means filter each ATM cell in accordance with the access control policy.

Abstract: In a system for the regulation of information trains for packet switches, there is provided one queue per path in each input module liable to be driven by an arbitrator placed in each of the output modules bearing these channels.
