Procedimiento para retransmitir datos en una red de datos descentralizada

摘要

The invention relates to a method for forwarding data in a local data network. In this context, a data network is considered in which a multiplicity of network nodes in a local data network form a first layer and tree nodes in a tree structure as a second layer are mapped onto the multiplicity of network nodes on the first layer, wherein a respective tree node is characterized by an explicit path in the tree structure and each path has an explicitly associated resource managed by at least one network node in the local data network. A suitable definition of explicit and ambiguous path sections which are used for queries at tree nodes in the tree structure means that the invention allows efficient routing with as few hops as possible between the individual network nodes. This is ensured particularly by the use of a peer-to-peer network with a distributed hash table as the local data network. Peer-to-peer networks provide a high level of failsafety, scalability and reliability. A preferred area of application for the invention is control networks for power supply networks, in which a tree structure for the control of the power supply network is mapped onto a peer-to-peer network. In this case, it is also possible for a plurality of tree structures to be generated and mapped onto the peer-to-peer network, depending on the application. The tree structures may be designed according to different criteria; an example of one criterion is the geographical situation of power producers in a power supply network. Another criterion is the type of power of the individual power producers.
