A network management system () of a communication network () determines members of a pool () of consumers () in the network management system (). Consumers are arranged to receive network management event data from network elements () of the communication network (). The network management system () determines members of a pool () of instances () of a network management application (A, B, N) in the network management system (). Instances of the network management application are arranged to process the network management event data. The network management system () determines a mapping between the pool () of consumers () and the pool () of instances () of the network management application (A). The mapping defines connections () for forwarding network management event data. Each of the connections is defined between a member () of the pool () of consumers and a member () of the pool () of instances of the network management application.
