摘要
为提高电力通信传输网的安全性和智能化水平,在分析电力通信传输网的技术难点、现有同步数字系列(synchronous digital hierarchy,SDH)网络的缺陷、自动交换光网络(automatic switched optical network,ASON)的技术优势的基础上,提出ASON与SDH网络配合使用的组网方式。为解决ASON技术不适于处理颗粒度为VC-12的电力通信业务的问题,给出具体的技术方案:首先通过SDH设备将颗粒度为VC-12的业务汇聚成颗粒度为VC-4的业务,然后进入ASON,在ASON层面实现业务调度和保护。
in order to improve safety and intelligence of power communication networks,the networking mode of integrating ASON with SDH networks is presented on the basis of analyzing technical difficulties of power communication networks,shortcomings of current synchronous digital hierarchy（SDH） and technical superiority of automatic switched optical network（ASON）.For tackling that ASON technique is unsuitable for managing power communication services with VC-12 granularity,the paper also gives a specific technical scheme：to converge service with VC-12 granularity into those with VC-4 granularity and then implement service dispatching and protection in ASON.
