摘要:

民航信息数据交换平台承担了大数据量的分布式传输任务,需要建立完善的任务调度模型和调度算法。基于民航信息交换平台的架构和需求,在分析比较现有的任务调度模型和调度算法基础上,提出适用于数据交换任务调度问题的解决方案,将点对多点数据传输网络映射为带约束的Steiner树模型,并用改进的遗传算法进行求解。实验仿真将此算法与最大带宽优先分配算法对比,结果充分验证了模型的正确性和可行性。

Abstract:

In order to support the distributed transmission of a lot of tasks on the data exchange platform for civil aviation information, it needs to establish the efficient task scheduling algorithms and models. Based on the infrastructure and needs of the platform, after analyzing the existing task scheduling models and scheduling algorithms, a new task scheduling model was proposed to fulfill the data exchange on this platform. This model mapped the point-to-multipoint data transmission network to a Steiner tree problem with delay and bandwidth constraints, and an improved Genetic Algorithm (GA) was also proposed to solve the constrained Steiner tree problem. The results of comparative experiment with the maximum bandwidth allocation algorithm prove the validity and feasibility of the proposed model.
