Abstract[English]
For a communication network using a satellite-involved backhaul, the backhaul outage and restoration states are predicted based on satellite motion data. Based on such predictions, devices providing the core portion of the communication network, and nearby Internet or backhaul radio devices can schedule or take actions. Actions can include but are not necessarily limited to: powering equipment up or down, suspending communications, migrating software from servers being powered down, transmitting replies to packets to indicate an anticipated outage and optionally anticipated outage end time, marking packets with congestion indications, closing or reopening certain ports, withdrawing or reinstating routing table addresses, and transmitting outage notifications to users or devices.[French]
Pour un réseau de communication utilisant une liaison de retour par satellite, les états de défaillance et de restauration d'une liaison de retour sont prédits sur la base des données de déplacement d'un satellite. Sur la base de ces prédictions, des dispositifs assurant la partie centrale du réseau de communication et des dispositifs radio proches, de liaison de retour ou Internet, peuvent planifier ou entreprendre des actions. Les actions peuvent, non exclusivement, consister à mettre un équipement sous ou hors tension, suspendre des communications, faire migrer un logiciel depuis des serveurs mis hors tension, transmettre des réponses à des paquets de façon à indiquer une défaillance anticipée et éventuellement une heure de fin d'une défaillance anticipée, marquer des paquets avec des indications d'encombrement, fermer ou rouvrir certains ports, supprimer ou restaurer des adresses de table de routage et transmettre des notifications de défaillances à des utilisateurs ou à des dispositifs.
