1. A computer-implemented method for adapting at least one pre-defined frame delay, wherein a corresponding at least one frame is communicated via at least one network switch of at least one computing unit in a frame-based computer network, and the at least one frame is received and forwarded by the at least one network switch which is extended with a monitoring or collecting capability, further wherein a traffic of the at least one frame is monitored by the at least one network switch, and the at least one pre-defined frame delay is an underlying or an associated resource reservation, the method comprising:
a. monitoring and collecting input data from the at least one network switch of the at least one computing unit; wherein:
b. the input data comprises at least one information associated with a queue occupancy of a storage unit of the at least one network switch, wherein the storage unit stores the at least one frame;
c. deriving at least one current frame delay of the at least one frame from the at least one information, wherein the at least one current frame delay is a change of the queue occupancy;
d. collecting a plurality of current frame delays over time for one frame to determine a statistical value of a current frame delay;
e. determining the at least one adapted frame delay by adjusting or correcting the at least one pre-defined frame delay using the statistical value of the current frame delay.
