A method of routing a subscription request defined by an event filter (510). The method includes parsing (610) the event filter (510) into an evaluation tree having at least one subexpression, locating the at least one subexpression (520) and determining (530) if the at least one subexpression includes a node (110) specific field. If the at least one subexpression (520) includes a node (110) specific field, the method includes creating a list (540) of nodes and event manager (310) contact information and transmitting the subscription request to at least one event manager (310) located on a node (110) that is included on a list (540) of nodes (110).
L'invention concerne un procédé d'acheminement d'une demande d'abonnement définie par un filtre (510) d'événements. Ledit procédé consiste à décomposer (610) le filtre (510) d'événements en un arbre d'évaluation comportant au moins une sous-expression; à localiser ces sous-expressions (520); et à déterminer (530) si les sous-expressions comportent un champ spécifique de noeud (110). Si les sous-expressions (520) comportent un champ spécifique de noeud (110), le procédé consiste à créer une liste (540) de noeuds et d'informations de contact du gestionnaire (310) d'événements; et à transmettre la demande d'abonnement à un gestionnaire (310) d'événements au moins se trouvant au niveau d'un noeud (110) faisant partie de la liste (540) de noeuds (110).
