摘要： The invention relates to a method for determining a termination point of at least one tunnel or tunnel segment in a packet switching network, the network comprising a set of routers (A, B, C, D, E, F, G) and links between them, each link having an associated cost, the set of routers and links forming a so-called previous network topology, a transit router (RTR) included in the set receiving packets intended for an output router (RSO) included in the set, an event modifying the previous topology into a so-called subsequent network topology, a backup path between the transit router and the output router being calculated for the packets based on the subsequent topology, the method comprising a calculation step prior to the event, where, for each of the routers of the set, a so-called initial tree (SPT(A), SPT(B), SPT(C), SPT(D), SPT(E), SPT(F), SPT(G)) is calculated based on the previous topology, said initial tree having as a root said router and having as branches the paths of minimum cost between the root and the other routers of the set, the method further comprising at least one cycle of steps for obtaining, based on the backup path and the initial trees, a termination point of a tunnel or tunnel segment intended to prevent the packets transiting between the start router and the output router from entering into a micro-loop caused by the event.

摘要： 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.
