自动交换光网络技术在广州电力通信网中的应用策略

Strategy for Applying Automatically Switched Optical Network to Guangzhou Power Communication Network

提出利用自动交换光网络(automatically switched optical network,ASON)技术进行组网优化,策略是在当前光纤加同步数字体系(synchronous digital hierarchy,SDH)网络的基础上引进ASON控制层面,利用现有的传送网络承载ASON业务;同时,提出建设ASON时应以骨干层为基础,在同等条件下应优先考虑同级别支持ASON智能特性的设备组网的建议。

The use of automatically switched optical network （ASON） is suggested for networking optimization. The strategy is introducing ASON control layer based on present optical fiber plus synchronous digital hierarchy （SDH）, and utilizing existing transmission network to support ASON business. It is also indicated that ASON should be constructed based on the backbone layer, and, under the same conditions, priority should be given to networking of same-level equipment that supports ASON smart features.
