In this paper we compare with Optical Burst Switching (OBS) and Optical Migration Capable Networks with Service Guarantees (OpMiGua) two all-optical network architectures. While delay is analyzed qualitatively, a quantitative performance evaluation based on simulations shows differences regarding loss probabilities. In order to achieve a maximum of comparability both models are fed with identical traffic on the packet level. Results show that OpMiGua has a better performance.
