Device and method for managing end-to-end connections

A device for managing end-to-end connections of a network within a central network management entity, the network including a plurality of end-to-end connections, wherein queues are assigned to the end-to-end connections, wherein each of the queues includes a data flow having data packets to be transmitted collectively, the device comprising:

• a processor;
• a state unit including instructions, the instructions, when loaded and executed by the processor, configure the processor to provide a current status of a quality of service parameter of a queue to which a new data flow is to be allocated;
• a resource allocation unit including instructions, the instructions, when loaded and executed by the processor, configure the processor to:
• allocate the new data flow to the queue based on a threshold for the quality of service parameter for the queue and the current status of the quality of service parameter of the queue;
• and
• a routing unit including instructions, the instructions, when loaded and executed by the processor, configure the processor to route the data packets of the new data flow based on the allocation;
• wherein a plurality of queues is assigned to an end-to-end connection and each of the queues has a different priority;
• and
• the resource allocation unit further includes instructions, the instructions, when loaded and executed by the processor, configure the processor to compare the threshold for the quality of service parameter and the worst-case value of the quality of service parameter of the queue to which the new data flow is to be allocated and is adapted to compare the threshold for the quality of service parameter and the worst-case value of the quality of service parameter of each queue having a lower priority than the queue to which the new data flow is to be allocated.
