A traffic network having a wired as well as a wireless network backbone is managed. The wireless network backbone has relay nodes having wireless routers, some acting as gateways to the wired backbone network and some as relay bridge routers for access network access. A management system has a logical multilevel hierarchical network overlying the traffic network. It is adapted to use the relay nodes as management stations. It performs a grouping process by arranging network nodes, including the relay nodes, in groups, each with a cluster head, on different hierarchical levels. A grouping controller controls the grouping and allocation of cluster heads based on a number of grouping constraints given by one or more criteria to be fulfilled at each hierarchical level. The criteria are calculated based on given metrics, the constraints are modeled, and fulfillment of the constraints is verified at each hierarchical level.

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 and maintaining a second repository for storing the set of event subscriptions. The node encodes a received event notification into a second summary and then checks if the received event notification is a member of the set by comparing the first summary and the second summary. If the event notification is not a member of the set said notification is discarded.

Method of processing event notifications and event subscriptions

The present invention relates to a proactive optimized link state protocol and a node with routing means supporting such a protocol implementing multipoint relaying for distribution of control messages, e.g. comprising hello messages, which are extended and comprise neighbour information, link status information and resource related information, and second control messages, e.g. TC messages comprising information relating to MPR selectors which are extended to also hold information of a shared information repository () adapted to hold generic service related information. Internal information repositories () are extended to additionally hold resource related information for neighbours, neighbour links and multipoint relay selectors. The protocol implements cross-layer () communication.
