摘要

PROVISION METHOD, NETWORK PROVISION ARRANGEMENT AND PROJECT TOOL FOR A COMMUNICATION NETWORK, AND ADMISSION CONTROLLER FOR A COMMUNICATION NETWORK In the area of network provision there is a problem of selecting a suitable traffic provision model. large networks due to the high complexity of resource-efficient stem medel administration and the poor bandwidth efficiency of the easy-to-configure hose medel. The invention is based on the idea of dividing (S1) at least part of the network into multi-node clusters, and defining (S2) traffic limitations on at least two levels, including intra-cluster level and inter-cluster level. where traffic limitations include one or more node-to-cluster traffic limitations for inter-cluster traffic. Subsequently, network clustering (S3) provisioning is performed based on traffic limitations. The modern grouping node limitations proposed by the invention are preferably applied to a cluster-based trunk or hose model at the level of intergrouping. In other words, for the description of trunk or hose models based on intergroup traffic grouping (traffic between groups) may preferably be used depending on the available traffic information. Cluster-based provisioning makes it possible to find a compromise between management complexity and over-provisioning.
