摘要
随着安徽省电力通信网的不断建设,SDH设备(Synchronous Digital Hierarchy,同步数字体系)作为传输承载网,网元数量在不断扩大。如何增强网络安全,提高工作效率,优化传输性能,成为通信网建设和改造项目需要考虑的核心要素。文章以安徽省A市为例,基于现有网络状况,从承载网的安全、效率、性能等方面分析,通过拓扑优化,分析优化前后网络可靠性、传输效率、传输性能的不同。提出基于地县一体化SDH网络结构的优化方案。
With the continuous construction of anhui electric power communication network, the elements number of SDH transmission network is constantly expanding.How to enhance the network security, improve the work efficiency, improve the transmission performance of the network, become the core problem of a communications network construction and technical transformation.In this paper, a city in Anhui province as an example, based on the existing network condition, we analyze network safety, efficiency, performance and other aspects. Through an example of topology optimization, the SDH network structure optimization scheme of prefecture-county integration is put forward.
