Abstract:
1. A method of processing event notifications and event subscriptions in a telecommunications or data network comprising a plurality of nodes, wherein an individual node performs the steps of: maintaining a first repository for storing a set of event subscriptions encoded in a first summary; maintaining a second repository for storing the set of event subscriptions, wherein the set of event subscriptions is indexed; hashing constraints of an event subscription; generating an index based on said hashed event subscription constraints; linking an identity of a subscriber node that forwarded said event subscription with said event subscription and storing this association in the second repository; hashing a received event notification to generate said notification's index; checking if an event subscription matching said event notification is recorded in said second repository, wherein the received notification is checked only against event subscriptions with indexes that match said notification's index; and if an event subscription matching the received event notification is found a subscriber node linked with said event subscription is identified and the event notification is routed to said subscriber node.
