Abstract:
1. A method of setting up a connection with a guaranteed Quality of Service via a transmission bottleneck for a packet-oriented communication network, comprising: administering transmission resources on the transmission bottleneck by a resource manager; transmitting connection information identifying an origin and a destination of the connection to the resource manager to set up a connection with guaranteed Quality of Service; reviewing the connection information at the resource manager and determining whether the connection is to be routed via the transmission bottleneck; depending solely on whether the connection is to be routed via the transmission bottleneck, generating a message specifying a level of transmission resources of the transmission bottleneck available currently; sending the message to the origin of the connection; and requesting the level of the transmission resources for the connection specified by the message, at the origin of the connection, as a function of the message; wherein the requested transmission resources are limited to a reduced resource requirement if the connection is to be routed via the transmission bottleneck; and wherein the transmission bottleneck is a single transmission link.
