摘要
随着业务需求的剧增,业内对直接承载业务的传输系统的安全性提出了更高的要求,OLP(光纤线路自动切换保护)以其响应速度快、切换时间短等特点,在高速率光传输网中获得了广泛应用,但同时也给网络的维护管理带来了新的问题和挑战。文章从OLP机制的原理入手,深入剖析OLP在现网应用中存在的实际问题,创新性地提出了OLP改进方案,该方案能更快、更好地适应未来业务质量的实际需要。
With the dramatic growth of service demand,higher requirements have been raised on the security of transmission systems that directly carry services.Characteristic of fast response and short switching time,OLP has been widely applied in high-rate optical transmission networks.However,it also brings about new problems and challenges to network maintenance and management.Starting with the principle of OLP mechanism,this paper analyzes in depth its practical problems in current network applications and proposes an innovative improvement scheme so that it can better meet the practical requirements for the quality of future services.
