Optical Internet is the next generation Internet that can meet the demand for high bandwidth and the study of its interconnection models is a hot spot in the current research.In this article

the basic trend that the peer model will take the place of the overlay model is analyzed and an intermediate model

i.e.hybrid model is presented on the basis of the comparison of the inherent three interconnection models

i.e.the peer model

overlay model and augmented model

which can support the coexistence of the peer model and the overlay model.The principle and mechanism for the realization of the hybrid model is highlighted.
