摘要
介绍了ASON层次路由的背景及结构,研究了ASON层次路由技术的研究热点和关键问题,并采用分类方法对近年来这方面研究发展的成果进行总结,分析说明虽然现有的层次路由算法很多,但各有其相对的优缺点,还需要进一步的完善。
The background and structure of ASON hierarchical routing were introduced, and its research hotspot and key problems were studied. With classification method, the research development results in recent years were summarized. The analysis shows that though there are many hierarchical routings, they have their own advantages and disadvantages, so the hierarchical routing in ASON should be improved.
