Claim:
A method for assuring quality of service of connections between a source and a destination subregion via an intermediate subregion in a packet-oriented network, where connection paths between subregions have prescribed transmission system resources, said method comprising: storing for access by a resource manager arranged in the packet-oriented network associated information relating to address ranges of the subregions, routes starting from the source subregion via the intermediate subregion to the destination subregion, and the transmission system resources between the subregions, but not within the subregions; signaling a requested scope of resources and source and destination addresses to the resource manager, when a connection is initialized; ascertaining in the resource manager a route through the network; and checking whether the connection to be initialized via the route is authorized in consideration of the requested scope of resources and the transmission system resources between the source subregion and the intermediate subregion and between the intermediate subregion and the destination subregion of the route, but not within the source, intermediate, and destination subregions of the route.
