北方某城市WDM/OTN网络评测浅析

Analysis of WDM/OTN Network Evaluation in a Northern City

基于对北方某大型城市WDM/OTN网络结构和基础数据的收集,从WDM/OTN的网络结构合理性、配置合理性、利用率合理性、过度保护及波分已用支路端口与业务网上联端口的匹配度等多个维度进行分析,发现WDM/OTN网络中的一些问题,给出网络优化建议,从而提高网络承载效率和投资有效性;并结合某城市群区域网络发展规划,提出了某地(市)满足未来网络健壮性需求的建设思路。

Based on the collection of WDM/OTN network structure and basic data in a large northern city,it analyses the rationality of WDM/OTN network structure,rationality of configuration,rationality of utilization ratio,excessive protection and matching degree between branch ports and service network ports,and finds some problems in WDM/OTN network.then it gives some suggestions for network optimization,so as to improve the efficiency of network load and the effectiveness of investment.Combining with the regional network development plan of a city group,the construction idea of the future network robustness of this city is put forward.
