Network parameters are tracked in a communication network, particularly in a packet-based IP network. A traffic matrix for the network is regularly ascertained and a blocking probability for traffic subject to an access control is determined from a current traffic matrix. A check determines whether the blocking probability satisfies a criterion for scheduled network operation. If the criterion is not satisfied and/or redetermination for limits used as part of the access controls using the current traffic matrix does not result in a blocking probability satisfying the criterion then the current traffic matrix is used to determine a new link/cost metric for optimizing traffic transport through the network. New values for limits used as part of the access controls are determined based on the new link/cost metric. If the criterion is then satisfied with the limits fixed at the new values, the link weights are configured with the new link/cost metric in the network and the limits are stipulated at the new values.

Method for tracking network parameters

The invention relates to a method and to a network control unit for deactivating a network component for example, one or several connections or an entire network node, the method being used to carry out deactivation in simple manner without impairing the traffic and optionally, the reliability. The invention also relates to a method for deactivating a network component, in particular one or several connections and/or a network node in a communication network including a plurality of network components. The method includes: a) the network components which are to be deactivated are identified; b) a new metric set (M) for the remaining network components is calculated c) the new metric set is configured in the network and the network is rerouted; and d) the network components which are to be deactivated are removed.
