旅客列车无线局域网带宽分配系统的研究与实现

摘要

旅客列车无线局域网带宽分配系统采用链路发现模块均衡9路链路负载,采用jhash_3words算法、RoundRobins算法构建用户发现模块,实时更新系统内真实用户数量.该系统优化了旅客列车无线局域网互联网出口的带宽分配方式,有效提升了互联网使用效率,通过了国家铁路产品质量监督检验中心的性能测试与功能测试,为在高速列车的实际运用奠定了基础.%In the wireless local area network(LAN) bandwidth allocation system for the passenger train, the link discovery module was used to balance the load of 9 road links, jhash_3words algorithm and Round Robins algorithm were used to construct the discovery module, update the number of real users in the system in real time. The system optimized the mode of bandwidth allocation, could effectively enhance the efciency in the use of the Internet. The system passed the performance test and the function test of the national railway product quality supervision and inspection center. It laid a solid foundation for the practical application in the high-speed train.
