A respective number of terminals are managed by network agents. When initializing a connection between two terminals, the network agent initializes the connection if the relevant terminals are arranged in the same bandwidth-uncritical area. If one of the terminals is arranged in a bandwidth-critical area, the network agent ascertains the requested bandwidth and sends a resource request to an associated bandwidth broker, which uses a topology function and knowledge of bandwidth used by existing connections to check the availability of the requested bandwidth in the bandwidth-critical area of the communication network. The use of network agents and the fact that resource requests are no longer required in the communication network dynamically reduces the load on bandwidth brokers and superordinate bandwidth brokers to a significant extent.

Method, network agent and bandwidth broker for managing the available bandwidth for connections between terminals of a packet-oriented communication network

Method for reserving bandwidth in a packet-oriented network, in which a packet-oriented communication link is set up between a plurality of network elements using at least one communication path. In this case, an identification number which is unique to the communication link and is intended to identify the communication paths associated with the communication link is allocated. A bandwidth value for a respective communication path is then determined as the maximum bandwidth required by network elements in this communication path, and bandwidth in the respective communication path is reserved using the bandwidth value.
