摘　　要：传统的资源分配方法往往只关注局部或单一目标,缺乏全局视角。这导致资源分配不能综合考虑整个网络的性能和需求,容易造成资源的局部过载或欠载,从而增加了资源的消耗比例。因此,提出了铁路通信网络异构链路传播资源高速分配方法。对传播资源分配环境进行处理,设计多目标资源分配节点,建立资源分配目标函数,资源分配量适应度排序,从而实现铁路通信网络异构链路传播资源高速分配。对比实验结果表明,该方法将资源消耗比例控制在0.02以内,较其他方法降低了0.06,具有较好的资源分配效果。Traditional resource allocation methods tend to focus only on local or single goals,lacking a global perspective.As a result,resource allocation cannot take into account the performance and requirements of the entire network,and it is easy to cause local overload or underload of resources,thereby increasing the proportion of resource consumption.Therefore,a high-speed distribution method of heterogeneous link communication resources in railway communication network is proposed.The communication resource allocation environment is processed,multi-objective resource allocation node is designed,resource allocation objective function is established,and resource allocation quantity fitness is sorted,so as to realize high-speed communication resource allocation in heterogeneous links of railway communication network.The comparative experimental results show that this method controls the resource consumption ratio within 0.02,reducing it by 0.06 compared to other methods,and has a good resource allocation effect.
