The invention relates to a system for reserving a pass band in a communication network including a centralised pass-band manager that implements a pass-band reservation protocol and that is connected to at least one host, characterised in that an external entity provides the pass-band centralised manager with a updated view of the logic topology of the network, and in that the pass-band centralised manager includes means for calculating, upon reception of a pass-band reservation request between a source and a destination for a certain traffic class, a current network path between the source and the destination using an algorithm, said path using at least one network link, and means for checking on each path link that there is a sufficient available pass band for the requested traffic class in the requested reservation. The present invention also relates to a communication device in communication network that implements a pass-band reservation protocol and that is connected to at least one host.
