A method for optimizing network performances, wherein the network includes one or more network nodes (1), performance parameters of the network nodes (1) being controlled by element of dedicated optimization modules (3), wherein each optimization module (3) monitors at least one performance parameter of the network node (1) to which the optimization module (3) is associated and generates a change request for the current value of the performance parameter on the basis of preset rules, is characterized in that the change requests generated by different optimization modules (3) of the network node (1) are forwarded to a shared controlling element (2), wherein the shared controlling element (2) enforces a coordination of the received change requests on the basis of a configurable algorithm. Furthermore, a corresponding system is disclosed.
