Abstract: A method for sending data packets encapsulated according to the MPLS protocol, and a sending device of an IP/MPLS network configured to implement the method. The sending method includes obtaining an identifier representative of a group of data packets having at least one data packet, inserting the identifier into at least one part of a data field associated with an entropy label of the MPLS protocol of the at least one data packet, and sending the at least one data packet in the IP/MPLS network.

Abstract: The invention concerns a method for routing a packet in a packet switching network in disconnected routing mode, implemented by a router, comprising the following steps:—receiving (E1) the packet;—reading (E2) a field, called the longevity field of the packet, intended to be decremented when traversing a router;—decrementing (E5) the value of the longevity field using a step of a predefined value, called the decrementation step;—deciding (E6) on the routing of the packet on the basis of the value of the decremented longevity field, the packet being destroyed (E7) when said value is less than or equal to zero; the method further comprising, prior to the step of decrementing, the following steps:—obtaining (E3) at least one item of information from a group of items of information comprising an item of information relative to routing conditions of the packet and an item of information relative to parameters of the packet;—determining (E4) the value of the decrementation step on the basis of at least the obtained information.

Abstract: A communication method implemented by a first router of an autonomous system using an interior gateway protocol. The method includes determining at least one flow control parameter for sending messages of the interior gateway protocol to the first router, the at least one flow control parameter being determined based on capacity of the first router to process the messages of the interior gateway protocol; and announcing, in a message of the interior gateway protocol, the at least one control parameter to at least a second router of the autonomous system, which is a neighbor of the first router.

Abstract: A method for prioritizing a packet flow. The method is implemented by a router node connected to a receiving node and includes: receiving a message containing an expected value of a protection parameter, from a device associated with the receiving node; and prioritizing packets containing the expected value of the protection parameter.

Abstract: A method for protecting a stream of packets in a network composed of packet router nodes and stream transmitter and receiver nodes. The receiver node is connected to a router node handling routing of a packet to the receiver node according to an expected value of a protection parameter included in at least one field of a packet of the stream. The method is implemented by a device associated with the receiver node and includes: transmitting to the router node connected to the receiver node a message containing the expected value of the protection parameter. A method is also provided for filtering a stream of packets, which is implemented by the router node connected to the receiver node and includes: receiving from a device associated with the receiver node a message containing the expected value of the protection parameter, and filtering packets not containing the expected value of the parameter.

Abstract: A method for determining a termination point of at least one tunnel or segment in a packet switching network. The network includes a set of routers and links between them, the routers and links forming a previous network topology, a transit router receiving packets intended for an output router, an event modifying the previous topology into a subsequent network topology, and a backup path between the transit router and the output router being calculated for the subsequent topology. The method includes calculating, prior to the event, for each router, an initial tree based on the previous topology, which has as a root the router and has as branches paths of minimum cost between the root and the other routers. A termination point of a tunnel or segment is obtained to prevent packets transiting between the start router and the output router from entering into a micro-loop caused by the event.
