随着3G移动通信系统IP化和面向IP全业务时代的到来,移动通信网络规模迅速发展,网络结构也愈加复杂,因自然灾害和施工导致的光缆线路故障时有发生,甚至导致一个或者多个县区业务全阻,给通信企业的运营带来了巨大的压力。主要探讨移动运营商城域传送网汇聚层面的网络现状和容灾应急保护机制,重点提出了跨环、跨地市等保护方式,并对按照方案实施后的效果进行分析。
With the advent of IP-based 3G mobile communication systems and the advent of IP-based services, the scale of mobile communication networks has rapidly developed and the network structure has also become more and more complex. Optical fiber line failures caused by natural disasters and construction have occurred from time to time, and even one or more All-county business block, to the communications business operations have brought tremendous pressure. It mainly discusses the network status and disaster recovery and emergency protection mechanism of mobile operator’s metro transport network convergence, and puts forward the protection methods such as cross-ring and inter-city, and analyzes the effect after implementation.
