Arrangement and Method Relating to Network Management
First Claim
1. A network management system for management of a traffic network comprising a wired network backbone and a wireless network backbone comprising a plurality of relay nodes comprising wireless routers, some of which acting as gateways to the wired backbone network and some of which acting as relay bridge routers supporting access of a number of access networks, said management system comprising a number of management stations arranged in a distributed manner and adapted to handle sub-networks of said traffic network,wherein the management system comprises a logical multilevel hierarchical overlay network, with a top or central manager, based on the infrastructure of the traffic network and adapted to use the relay nodes as management stations, that it comprises grouping means adapted to perform a grouping process by arranging network nodes, comprising the relay nodes, in groups or clusters, each with a cluster head, on different hierarchical levels, and further comprising grouping control means adapted to control 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, calculating means adapted to calculate the criteria based on given metrics, and modelling and verification means for modelling the constraints and verifying fulfilment of said constraints at each hierarchical level.

Abstract
The present invention relates to a network management system for management of a traffic network comprising a wired as well as a wireless network backbone. The wireless network backbone comprises relay nodes comprising wireless routers, some acting as gateways to the wired backbone network and some as relay bridge routers for access network access. The management system comprises a logical multilevel hierarchical network overlying the traffic network. It is adapted to use the infrastructure of the traffic network by using the relay nodes as management stations. It comprises grouping means adapted to perform a grouping process by arranging network nodes, comprising the relay nodes, in groups, each with selected a cluster head, on different hierarchical levels. Grouping control means are provided to control 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. Calculating means are adapted to calculate the criteria based on given metrics and modeling and verification means are provided for modeling the constraints and verifying fulfillment of said constraints at each hierarchical level.

18. A method for managing a traffic network comprising a wired network backbone and a wireless network backbone comprising a plurality of relay nodes comprising wireless routers, some of which acting as gateways to the wired backbone network and some of which comprising relay bridge routers for access of access networks, said method comprising the step of:
-
arranging a number of management stations in a distributed manner to handle sub-networks said traffic network, wherein the arranging step comprises; arranging the management system as a logical, hierarchical network overlying said traffic network; using the infrastructure of the traffic network defining the relay nodes as management stations, by defining a number of metrics and representative of the traffic network characteristics to set up criteria; performing, at different levels, a grouping process by arranging network nodes in groups or clusters; for each group, on each level, selecting an overlying cluster head, and in the top layer providing a top, central manager, said grouping process comprising; modelling a number of constraints based on said criteria; verifying fulfilment of said constraints at each hierarchical level. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
