Title: Routing functionality application in a data communications network with a number of hierarchical nodes

Abstract: A data communication network with a number or origination nodes, a number of destination nodes and a number of intermediate nodes, in which messages are sent from origination nodes via a number of intermediate nodes to destination nodes and in which nodes are added and/or removed in an unpredictable way, has a basic functionality software system accessible via a number of destination nodes. Through the basic functionality software system, a functionality application is made available in at least one destination node and a routing application is associated with the functionality application so that when the functionality application is installed in a node, the routing functionality is automatically provided whereupon the functionality application is presented/offered to other nodes in higher layers. When the functionality application is fetched by an overlying node, such node is also provided with the routing functionality so that the degree of controlling the availability in the network is gradually increased with the number of nodes fetching the functionality application. Methods of increasing the availability in a data communication network are also described.
