Abstract
A system of a plurality of interconnectable nodes for modelling states; wherein one predetermined node is configured to act as a master node, the master node being configured to instantiate a state by creating the state and distributing the created state to at least one of the nodes, the master node being further configured to modify a state by changing the state and distributing the changed state to at least one of the nodes, the master node being further configured to maintain an indication of 'owner of process' assigned to exactly one of the interconnectable nodes at a time; wherein a first node not being the master node but being indicated as 'owner of process', is configured to cause the master node to instantiate a state or to modify a state; wherein the first node is further configured upon receiving a request for instantiating or modifying a state from a second node to decide whether or not to accept the request of the second node and to cause the master node to instantiate a state and to modify a state, such that the first node needs not to be connected at the time the second node is sending the request to perform a state change.
