摘　　要：海洋信息通信网是一个高度动态且复杂的环境,其中包含了众多不同的节点和链路,路由协议的作用至关重要,开放最短路径优先是广泛使用的路由协议之一,它基于链路状态进行路由决策。在开放式最短路径优先(Open Shortest Path First,OSPF)中,链路开销(Cost)值是一个关键参数,它表示通过特定链路发送数据的成本。这个成本通常与链路的带宽、延迟、可靠性等因素有关,涉及路由协议的参数调整与对新型路由策略的探索和应用。随着海洋活动的日益增多,海洋信息通信网的重要性不断提升,对其进行深入研究和优化具有重要的实际意义。本文主要对海洋信息通信网中Cost值对路由选路作用进行研究,通过分析OSPF在海洋信息通信网中的应用及Cost值在海洋信息通信网中的选路作用,进一步研究不同Cost值对网络资源分配的影响,为网络流量的合理使用提供技术支撑。The ocean information and communication network is a highly dynamic and complex environment,which contains numerous different nodes and links.The role of routing protocols is crucial,and open shortest path priority is one of the widely used routing protocols,which makes routing decisions based on link status.In OSPF(Open Shortest Path First),the Cost link cost value is a key parameter that represents the cost of sending data over a specific link.This cost is usually related to factors such as bandwidth,latency,and reliability of the link,involving parameter adjustments of routing protocols and exploration and application of new routing strategies.With the increasing number of ocean activities,the importance of ocean information and communication networks continues to rise,and conducting in-depth research and optimization on them has important practical significance.This article mainly studies the effect of Cost link cost values on routing in marine information communication networks.By analyzing the application of OSPF in marine information communication networks and the routing effect of Cost link cost values in marine information communication networks,further research is conducted on the impact of different Cost link cost values on network resource allocation,providing technical support for the rational use of network traffic.
