Abstract:
1. A method of processing event subscriptions in a telecommunications or data network comprising a plurality of nodes organised in clusters, in multiple layers, each cluster having a cluster leader, wherein the method comprises: maintaining by each node a routing table comprising a list of nodes in its cluster and a repository of event subscriptions; forwarding an ascending subscription by a node to all nodes within its cluster and to the cluster's leader; forwarding by the node a descending subscription to all nodes of all layers that the node is a leader; and adding a received event subscription to the event subscriptions repository and associating said subscription with a node, which forwarded it, wherein upon reception of an ascending event notification by the cluster leader the method further comprises forwarding said ascending event notification to any node if a subscription for this event has been previously forwarded by said node to said cluster leader.
