Abstract
In the area of network provisioning, there is a problem of selecting a suitable traffic-provisioning model for large networks due to the high management complexity of the resource-efficient trunk model and the poor bandwidth efficiency of the easy-to-configure hose model. The invention is based on the idea of partitioning at least part of the network into multi-node clusters, and defining traffic limitations on at least two levels, including the intra-cluster level and the inter-cluster level, where the traffic limitations include one or more node-to-cluster traffic limitations for inter-cluster traffic. Subsequently, cluster-based provisioning of the network is performed based on the traffic limitations. The novel node-to-cluster limitations proposed by the invention are preferably applied in a cluster-based trunk or hose model on the inter-cluster level. In other words, for the description of the inter-cluster traffic (traffic between the clusters) cluster-based trunk or hose models can be used, preferably depending on the available information about the traffic. The cluster-based provisioning makes it possible to find a trade-off between management complexity and overprovisionin…
