近海工程船只IBS环网设计与关键技术研究

Design and Key Technology Research of IBS Ring Network on Offshore Engineering Vessels

根据近海工程船只实际情况,设计了一体化船桥网络。采用光纤环网组网方式,利用核心交换机和接入交换机同时工作,同时针对当前存在的几种环网保护协议做了一些探讨,重点介绍了RRPP环形网络保护协议,并在此基础上划分虚拟局域网,实现网络广播风暴的隔离,保证数据流量的合理传播,并简单探讨了3G及现场总线技术的应用。

Bridge network integration is designed according to the real situation of offshore engineering vessels. The optical fiber ring network mode is used, so is the core switches and access switches work, and some existing ring protection protocol is discussed, the RRPP ring network protection protocol with emphasis is introduced, and virtual LAN is divided to realize isolation of network broadcast storm, to ensure proper communication data flow on the basis of this, and talked about the application of 3G and fieM bus technology simply.
