基于特大型城市双千兆覆盖需求的传送网优化研究

The network optimization based on double gigabit coverage in ultra large scale metro

为了应对双千兆覆盖的巨大承载压力,提升特大型城市传送网的优化效果,实现标本兼治,本文在当前光纤基础网架构和建设标准的基础上,阐述了传送网优化需求,分析了优化存在的问题。基于以上需求和问题,探讨和比对了“宏”与“微”优化方向选择,形成基于微网格的优化思路。通过建立健康度指标体系,提出具体的评估和测算方法,最终对特大型城市基于微网格的传送网优化提出了指导意见。

This paper introduces the transport network optimization requirements and analyses problems existing in optimization on the basis of clear optical fiber based network architecture and construction standards in order to enhance the effect of the transport network optimization in large and medium size cities.This paper also discusses and compares the choice between"macroscopic"and"microcosmic"based on the needs and problems above.Here,the idea of optimization based on microgrid is formed.Specific evaluation and calculation method is proposed by setting up a health index system.Finally this paper gives the guidance of optimization of transmission network based on microgrid in large and medium cities.
