A computer implemented method for Quality of service QOS aware unified control protocol for optical burst switching in software defined networks comprising the steps of:
- employing an adaptive burst assembling protocol for providing network state information and application latency requirements;
- using a latency aware burst routing for determining burst routing and scheduling while observing a wavelength continuity restraint responsive to said adaptive burst assembling protocol;
- utilizing OpenFlow protocol extensions for realizing a QOS aware unified control protocol for optical burst switching OBS;
- and
- carrying out the QOS aware unified control protocol for performing burst routing and burst scheduling operations using the latency-aware burst routing, estimating a burst size for future arrival of traffic using the burst estimation.
