A method of processing event subscriptions in a telecommunications or data network comprising a plurality of nodes organized in clusters, in multiple layers. Each cluster has a cluster leader. 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 its cluster's leader; forwarding 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.
