  • Publication number: 20120096476
    Abstract: A virtual event channel configuration method according to an aspect of the present invention is a method for configuring and managing at least one virtual event channel by combining a plurality of event channels, in which each of the at least one virtual event channel comprises the steps of: receiving an event from at least one event sender; registering an event subscriber who wants to subscribe the sent event and an event filter designated by the event subscriber; validating whether the event filter designated by the event subscriber has an error in a given event filter grammar; and extracting an event to be sent from the received events using the event filter, if the event filter is validated. Accordingly, an event is received by dynamically combining interesting event channels, and thus it is possible to reduce an overhead due to unnecessary event processing.
