This paper provides an analytical basis for comparison of reservation policies in Optical Burst Switching (OBS) networks. In particular, the Just-Enough-Time (JET) and Burst Segmentation policies are analysed. We first compare these two policies using single link models and then we extend these models to a network scenario using a reduced load fixed point approximation model to evaluate blocking probabilities. We use this analysis framework to provide insights into the significant advantages provided by the Burst Segmentation policy for OBS networks, taking into account network related effects which cannot be studied by single link models alone.
