摘要

宁夏数字地震观测网络项目信息服务分项项目组作为整个网络系统集成组,在信息网络系统的建设过程中,依据不同地震观测项目对信道速率、连续率、实时性、网络延时等通信要素的不同要求,考虑到不同节点的基础通信条件的差异,在采用平面星型网络拓扑结构作为总的通信策略的同时,实地考察、科学分析、统一规划、综合布局,对不同类型的节点分别采用不同的通信信道组合策略作为节点的接入方式,采用以OSPF为主要路由协议的多路由协议集成,全面解决了宁夏数字地震观测网络项目的整体通信和路由融合问题,同时也为其他观测项目的数据传递和汇聚提供了可靠的通信网络平台。
In construction of the earthquake information network for Ningxia Hui Autonomous region which is the part of Ningxia digital seismic monitoring network, different communication requirements, such as channel rate, continuous rate, real-time character, and network delay are taken into account. We introduced flat-star network topology as the overall communication strategy in the construction of network systems. At same time, we applied different communication channels portfolio strategy for different type of nodes respectively and took OSPF routing protocol as the main protocol in multi-routing protocol integrated strategies. With such comprehensive effort, we successfully fulfilled the overall integration of communications and routing of the digital seismic monitoring network subject in Ningxia, and built up a reliable communications network platform for data transfer and influx.
