基于SDH和ADSL双链路冗余的通信网络设计与实现
|
摘要
为有效解决数字地震观测通信网络不稳定的问题,提出了基于SDH和ADSL双链路冗余的通信网络设计思想。对通信网络需求及特点进行分析,设计了通信网络的拓朴结构和组网方案,然后通过调整不同路由协议之间的管理距离值和主备链路代价值的方法,设计了基于SDH和ADSL双链路互为备份和自动切换的路由策略,实现了通信网络的高可用性。网络的实际运行结果表明了该设计思想的有效性和可行性。
To solve the instable problem of communication network for digital seismic monitoring effectively, a design idea of communication networks based on SDH and ADSL dual-link redundancy is proposed. Firstly, by analyzing the requirements and characteristics of communication networks, the topological structure and networking scheme of communication network are designed. Then, by adjusting the value of administrative distance (AD) among routing protocols and adjusting the value of cost between major link and backup link, a routing strategy based on SDH and ADSL dual-link redundancy and automatic switching is designed, so the high availability of communication networks is realized. Finally, the efficiency and feasibility of the design idea is demonstrated by the practical operation results of communication networks.
