Telecommunication network and state propagation method

摘要

According to the invention, a telecommunication network comprises an operation and maintenance device and a plurality of network elements each of them comprising hardware objects. At least one network element communicates state changes to the operation and maintenance device. The operation and maintenance device comprising a memory device and a processing device. The memory device stores a state dependency graph with objects, states of the objects and operators, and a set of rules allocated to the operators. The processing device processes the communicated state changes by applying the rules to the operators of the graph and calculates the new states of all objects that depend on the communicated state change. <IMAGE>
