Abstract: An arrangement, a system and a method provide communication between clients and managed systems via managing systems. The clients communicate with the managing system over a first network using an IP-protocol, and a managing system(s) communicate with a number of managed systems over a second network. Each managing system includes a service management node with an information handling device for separating addressing information from other information of an incoming message and for adapting the information to the communication protocol used for communication with the addressed managed system.

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.
