一种面向NTN网络转发模块的研究实现

Research on forwarding module of node-to-node network

NTN(node-to-node)横联远距离无线移动通信系统转发模块是基于MAC地址转发原理,每个节点维护一张包含下一跳节点信息的路由表。文章在当前无线自组网路由协议的理想要求上,比较路由协议的常规问题,分析转发模块设计方案的特点,同时从6个方面研究转发模块。测试结果表明,该MAC协议转发模块可实现全网MAC的学习、转发路径的计算、拓扑去环功能,支持横联内部设备相互通信、外设与外设通信。

The forwarding module of node-to-node（NTN） communication system with some characters of transverseness, long-distance, wirelessness and mobility is based on the MAC address forwarding theory in which each node maintains a routing table of containing the next hop information. In view of the general requirements of the wireless ad hoe networks currently, the general problems in routing protocols are compared, and the features of the design of forwarding module are analyzed. Moreover, the forwarding module is studied from six specific aspects. The results indicate that the MAC protocol forwarding module achieves the functions of network-wide MAC learning, the calculation of forwarding path and cutting the ring of topology. It also makes transverse devices communicate with each other and the peripherals communicate in network.
