A method for establishing connections with guaranteed quality of service for a communication network with a Resource Manager

According to the inventive method, transmission resources of one or more individual transmission links (US), especially of individual transmission bottlenecks, are managed by a resource manager (RM). In the course of a setting up of a connection (V), the resource manager (RM) determines, by using an item of connection information (VI), the origin (EG1) and destination (EG2) of the connection (V) to be set up, and identifies whether this connection is routed over a particular transmission link (US). Based on the result of the determination, a message (M) is subsequently generated and transmitted to the origin (EG1) of the connection (V). A selection of transmission resources to be used for the connection (V) is then carried out based on the transmitted message (M).
