摘要

EON（弹性光网络）中动态业务初次分配后会产生频谱碎片

影响后续业务的分配和网络的资源使用率。频谱碎片是EON RSA（路由和频谱分配）算法中需要考虑的核心问题之一。文章提出了一种改进的基于频谱碎片权值评估的EON RSA算法

引入新的评估参数DF（碎片离散度）

并在选路时进行考虑。理论分析和仿真结果表明

与传统RSA算法相比较

改进算法可以降低频谱碎片离散度

提高频谱资源利用率。

Abstract

The initial resource allocation for dynamic service requirement may lead to frequency spectrum fragment in Elastic Optical Networks（EON）

which will influence the allocation and resource efficiency of subsequent services.Spectrum fragment is one of the core problems for Routing and Spectrum Allocation（RSA）.This paper proposes an improved RSA algorithm for EON based on weights evaluation of spectrum fragments.This improved algorithm considers the Dispersion of Fragmentation（DF）as new parameter for evaluating spectrum fragments.Theoretical analysis and numerical simulation results show that compared with traditional RSA algorithm

the proposed algorithm can reduce the spectrum fragments degree and enhance the using rate of spectrum resources.
