Abstract

L'invention concerne un système de communication (1) configuré de telle sorte qu'une pluralité de nœuds de communication puissent exister dans une zone de service et configuré en incluant une pluralité de nœuds de transfert (10) qui effectuent un traitement de relais de paquets transmis et reçus entre deux nœuds de communication et un nœud de gestion (20) qui mémorise des informations de nœud, constituant des informations indiquant le nœud de transfert (10) en tant que cible à l'intérieur de la zone de service pour chaque nœud de communication de la pluralité de nœuds de communication, désigné lorsque le traitement de relais est réalisé dans la pluralité de nœuds de transfert (10). Le système de communication (1) comprend : une unité de prédiction (203) qui prédit une future cible de communication par chaque nœud de communication de la pluralité de nœuds de communication en fonction de journaux de communication des paquets et enregistre des informations sur la cible de communication dans des informations de nœud correspondant au nœud de communication ; et une unité de transmission d'informations de nœud (204) qui transmet les informations de nœud par chacun de la pluralité de nœuds de communication à l'avance au nœud de communication (10) correspondant aux informations sur la cible de communication enregistrée dans les informations de nœud.
