Abstract: A network node comprising at least one network interface the network node arranged to form network links to other network nodes through the or each network interface, each network link being to a neighboring one of the other network nodes, the network node arranged to determine whether data transmitted over the links to the relevant neighboring network nodes is successfully received. Should the network node make a first determination that data sent over a given network link to a neighboring node has not been successfully received, the network node temporarily disables the entry for that network link in a memory for a period of time, such that the network node does not send data to the neighboring node over the given network link during the period of time, but then subsequently re-enables the entry after the period of time has elapsed.

Abstract: 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 (4) adapted to hold generic service related information. Internal information repositories (231i, 232, 233) are extended to additionally hold resource related information for neighbours, neighbour links and multipoint relay selectors. The protocol implements cross-layer (21, 22, 23) communication.

Abstract: The present invention relates to a node supporting networking and communication with other nodes by means of a layered communication protocol and group communication with other nodes controlled via a grouping protocol adapted to interact with said communication protocol. The node comprises a policy engine which is arranged separately from, but in communication with said grouping protocol. The policy engine is adapted to establish current and/or changing node, group and network related information and to use one or more grouping policies to automatically and dynamically control grouping related actions and adapt the grouping. The invention also relates to a system comprising a number of such nodes and a method of controlling grouping.

Abstract: The present invention relates to a network management system, a network element and a method for managing the network management system, the system operating in a computer or telecommunication network. The network comprises at least one network element that is able to communicate in the network through links. A network management software is contained and run on the network element. According to the present invention the network management software comprises controlling means for each management function or functions that the network element is part of, the controlling means being able to form, reform and/or terminate the topology for the management function. It further comprises register means for each management function or functions that the network element is part of, the register means being able to register and share information about the topology for the management function.
