摘要
由于目前的网络主动缓存方法对于用户不同需求的分配计算不佳,导致带宽分配效果较差,影响网络的效用值,因此提出基于用户QoS速率需求的5G网络主动缓存方法,并给出其实现过程。根据不同用户的QoS等级进行划分,计算需求的带宽。通过设计分布式缓存下的用户管理运算,确定用户的缓存效用函数。为了验证设计方法的可行性,设计实验,运用OAI来开发5G网络的缓存仿真环境,并使用设计方法与传统方法进行对比,实验结果显示,设计方法的网络吞吐量更高,证明其网络效用情况更优,符合设计初衷。
In the current network active caching method,due to the poor allocation calculation for different needs of users,the bandwidth allocation effect is poor,which affects the utility value of the network.In this paper,a 5G network active caching method based on user QoS rate requirement is proposed.Firstly,it is divided according to the QoS level of different users,and the required bandwidth is calculated.The user management operation under distributed cache is designed to determine the user’s cache utility function.Finally,the implementation process of active caching is given.In order to verify the feasibility of the design method,the design experiment uses OAI to develop 5G network cache simulation environment,and uses the design method to compare with the traditional method.The experimental results show that the design method has higher network throughput,which proves that the method has better network utility and meets the original design intention.
