光互联网中基于集成模型的流量工程研究

The analysis of integrated traffic engineering in optical Internet

光互联网是一种简洁、高效、经济的网络体系结构,流量工程是其中的一个重要方面.文章在对IP层和光层流量工程进行分析的基础上指出了重叠模型流量工程的弊端,提出在光互联网中应采取集成模型的流量工程,并对其机制进行了研究,同时还对如何优化IP层和光层的流量工程代价分配进行了分析.

Optical Internet is a compact, efficient and ecomonic architecture for future communication networks, therein the traffic engineering is an important aspect. This article indicated the deficiencies of overlay model on the basis of the analysis of traffic engineering in IP layer and optical layer, proposes integrated traffic engineering in optical Internet,and discussed how to optimize the traffic engineering in IP layer optical layer for obtaining the minimal total traffic engineering cost.
