摘　　要：对云计算通信网络信息下载进行均衡调度,可以避免网络发生拥塞,保障云计算通信网络的高效运转。进行网络信息下载均衡调度时,由于云计算通信网络具有时变耦合性,导致在信息下载过程中,无法快速随机选择节点,而传统方法就是通过对随机节点上的下载任务进行分配完成信网络信息下载均衡调度,导致传统方法存在均衡度较差的问题。提出TDSCDMA云计算通信网络信息下载均衡调度优化算法。首先利用信息下载任务的预测完成时间和成本开销定义均衡适应度函数,并采用遗传算子全局搜寻适应度函数最优解,然后将获得的全局搜寻适应度函数最优解定义为信息下载均衡调度特征参数,组建调度特征参数权重分派机制,计算正交加权限制均衡比,依据信息正交加权限制均衡比进行模糊循环迭代控制,实现通信网络信息下载均衡调度。仿真结果表明,所提算法进行云计算通信网络信息下载均衡调度优化时,信息下载的均衡度较高,且计算效率较快。An optimization balance scheduling algorithm of information download in the TD- SCDMA cloud computing communication network is proposed. The time and cost of prediction completion for information download task are used to define balance the fitness function. And genetic operators are used to search for the optimal solution of the fitness function. Then the optimal solution of the global search fitness function is defined as the characteristic parameter of the information download balance scheduling to set up scheduling characteristic parameter weight assignment mechanism,and the orthogonal weighted limit balance ratio is calculated. According to the information orthogonal weighted limit balance ratio,a fuzzy loop control is carried out to achieve the balance scheduling of communication network information download. The simulation results show that the proposed algorithm has high balance degree and fast computation efficiency.
