摘要
ASON技术融合了SDH的功能特性、高效的IP技术、大容量的DWDM和网络控制功能,具有高速率、高带宽、高覆盖和高可靠性的特点。分析了智能光网络的3种模型和功能结构,且ASON基于格状网的恢复技术,可以为光纤通信网带来更灵活的网络结构、更多样的业务保护策略和更可靠的业务生存能力,也可以降低网络运营总体成本。针对ASON的特点,提出了分布式的恢复与保护机制,并分析了其优点,对通信网的建设具有一定的参考意义。
With the characteristics of high speed,broad bandwidth,higher coverage ratio and reliability,ASON technology combines SDH functions,high-efficiency IP technology,large capacity DWDM and network control function together. The model and structure of ASON been analyzed,and the structure of fiber communication net will been more freely because of the technology of restoration based on grid network,also it has multiple strategies of work protection and more reliable survival ,final the cost of network business m...
