信息化跨区域网络时延最小化资源分配方法研究

Research on Resource Allocation Method for Information Trans-regional Network with Minimum Delay

为提升资源分配均衡性及网络传输实时性,提出信息化跨区域网络时延最小化资源分配方法.基于信息化跨区域网络模型特点及传输时延问题,以信息化跨区域网络不同类别资源均衡分配、网络总时延最小化为目标,以各跨区域网络资源分配总权重等于1为约束条件,构建信息化跨区域网络时延最小化资源均衡分配模型.结合贝克曼变化思想求解构建模型,通过网络资源的分流转化,获取资源均衡分配并且总时延最小的资源分配结果.实验结果表明:该方法可以更好地分配信息化跨区域网络资源,避免信息传输时出现丢包问题和网络拥塞问题;资源分配后降低了信息传输的时延抖动、本地传输和跨区域传输时延,提升了信息传输效果.

In order to improve the balance of resource allocation and the real-time performance of network transmission,this paper proposes a resource allocation method of information trans-regional network with delay minimization.Based on the characteristics of the cross-regional network model and the transmission delay problem,this paper constructs the information cross-regional network delay minimization resource balanced allocation model with the goal of balanced allocation of different types of resources and the total network delay minimization,and with the constraint that the total weight of each cross-regional network resource allocation is equal to 1.Combining with Beckman’s change idea to solve the construction model,this paper obtains the resource allocation results with balanced resource allocation and minimum total delay through the diversion and transformation of network resources.The experimental results show that this method can better allocate information cross-regional network resources and avoid packet loss and network congestion during information transmission;After resource allocation,the delay jitter in information transmission,local transmission and cross-region transmission delay are reduced,and the information transmission is improved.
