METHOD OF PROCESSING EVENT NOTIFICATIONS AND EVENT SUBSCRIPTIONS

摘要

A method of processing event subscriptions in a telecommunications or data network (100) comprising a plurality of nodes (A - R) organised in clusters (102 - 126), in multiple layers (L0 - L3). Each cluster (102 - 106) has a cluster leader (A, B, C). The method comprises maintaining by each node (A - R) a routing table comprising a list of nodes in its cluster and a repository of event subscriptions; forwarding (410) an ascending subscription (404) by a node to all nodes within its cluster (202, 206) and to its cluster's leader (204, 208); forwarding (420) a descending subscription (404) to all nodes of all layers that the node is a leader (218 - 222) and adding a received event subscription to the event subscriptions repository and associating said subscription with a node, which forwarded it.
