合肥电力通信华为ASON光传输网络优化改造
|
摘要
以合肥地区为例,探讨了合肥供电公司所辖范围内电力通信华为ASON光传输网络现状及存在的问题,指出了目前华为ASON网域中智能网元数目过多,存在光缆中断时主控板无法重新计算路由的隐患。提出了一种重新划分智能域的方法并制定了详细的网络优化方案。本方案有效解决了合肥地区因ASON网域中智能网元数目越限所导致重路由失败等的问题,使得ASON智能网业务保护能力的优势得以充分发挥。
Taking Hefei as an example, this paper discusses the current situation and existing problems of Huawei ASON optical transmission network for power communication within the jurisdiction of Hefei Power Supply Company, and points out that there are too many intelligent network elements in Huawei ASON domain at present, and there are hidden dangers that the main control board can not recalculate routing when the optical cable is interrupted. A method of repartitioning the intelligent domain is proposed and a detailed network optimization scheme is worked out. After the implementation of this scheme, the problem of re-routing failure in the Hefei area due to the limitation of the number of intelligent network elements in the ASON domain is effectively solved, and the advantages of the ASON intelligent network service protection capability can be brought into full play.
