弹性光网络中碎片问题的研究
Research on the fragmentation problem in elastic optical network
摘要
Abstract
Elastic optical networks (EON) should be suitable for the two constrains of wavelength continuity and spectrum continuity when routing and spectrum matching. As a result, there will be a great deal of frag-mentation in the network spectrum when building and terminating lightpaths in a dynamic manner. In order to improve the degree of EON fragmentation, this paper proposes a dynamic routing and dynamic spectrum fiting (DRDSF) strategy, and builds an experimental model to simulate the business blocking rate and spectrum re-source utilization. The experimental results show that the DRDSF spectrum is more effective in controlling the spectrum fragmentation in EON dynamic business environment, compared with the traditional defragmenta-tion cleaning mechanism. What is more, network performance can be improved significantly.关键词
