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. Should the network node make a subsequent determination that data sent over the given network link to the neighboring network node has not been successfully received, the network node deletes the entry from the memory.

Network nodes

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.
