METHOD AND APPARATUS FOR THE DYNAMIC FILTERING AND ROUTING OF EVENTS

摘要

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 no de (110) that is included on a list (540) of nodes (110).
