光因特网互联模型研究与演进

Research in and evolution of interconnection model of optical Internet

光因特网是能提供高带宽的下一代因特网,对其互联模型的研究是目前光因特网研究中的一个热点。文章分析了互联模型由重叠模型向对等模型演进的基本趋势,并在对比固有的3种互联模型———对等模型、重叠模型及增强模型的基础上,提出了一种新的演化模型———混合模型,这种模型能够支持对等模型与重叠模型的共存,文章对其实现的原理与机制进行了论述。

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