摘要
Optical burst switching (OBS) provides a future-proof alternative to the current electronic switching in the backbone. In this letter, we study a horizon-based single-channel multi-class OBS node, for which the multiple traffic classes are differentiated using a different offset time of each class. By assuming Poisson burst arrivals and general burst size distribution, using the well-known level crossing method, we obtain the expressions of per-class blocking probabilities. We validate our results using a numerical example.
