摘要
本文综述了柔性光网络中动态路由和频谱分配(RSA)问题的研究现状。现有的RSA算法主要分为三类:FR (fixed routing)、FAR (fixed alternative routing)和AR (adaptive routing)。我们从每一类算法中选取了具有代表性的算法，并简要介绍了它们的概念、优缺点。对这些算法在阻塞性能、计算复杂度等方面进行了比较。
Dynamic routing and spectrum assignment algorithms in flexible optical networks: An overview
In this paper, we examine the current research on the dynamic routing and spectrum assignment (RSA) problem in flexible optical networks. The existing RSA algorithms are classified into three main categories: fixed routing (FR), fixed alternative routing (FAR) and adaptive routing (AR). We select the representative algorithms within each category, and briefly introduce their concept, advantage and drawback. Comparison among these algorithms is made in respect of blocking performance, computational complexity and so on.
