Abstract:
1. A computer-implemented apparatus for link capacity dimensioning for a communication network having a set of network nodes interconnected by links, said computer-implemented apparatus comprising: a cluster selector for logically partitioning a number of said network nodes into clusters, each cluster having at least two nodes; a service level controller for defining a cluster-based service level definition including intra-cluster level and inter-cluster level definitions, said cluster-based service-level definition including at least one hose-based limitation for intra-cluster traffic on the intra-cluster level and at least one trunk-based node-to-cluster limitation for inter-cluster traffic on the inter-cluster level; and a dimensioning controller for dimensioning the capacity of a number of said links based on a cluster-based trunk model involving said at least one trunk-based node-to-cluster limitation for inter-cluster traffic on the inter-cluster level and a cluster-based hose model involving said at least one hose-based limitation for intra-cluster traffic on the intra-cluster level.
