摘　　要：分布式媒体网络常面临因网络流量分配不均而导致的信道利用率低的问题。基于此,文章提出了一种基于SDN的分布式媒体网络多信道访问控制技术。由数据收集、安全分析、策略制定和管理模块等内容组成,SDN安全控制器可实现全局网络状态监控和集中安全策略管理。文章采用AHP建立用户信任评估机制,从而量化用户信任度。最后,基于信任度设计多信道访问控制策略,确保其能按需、高效、安全地分配信道资源。实验表明,该技术的平均信道利用率达99.7%,能有效应对网络负载变化和复杂用户行为,应用效果较好。In distributed media networks,the problem of low channel utilization is often caused by uneven distribution of network traffic.Based on this,this paper proposes a distributed media network multi-channel access control technology based on SDN.This method is a SDN security controller composed of data collection,security analysis,policy formulation and management modules to realize global network status monitoring and centralized security policy management.Then,AHP is used to establish the user trust evaluation mechanism,so as to quantify the user trust.Finally,a multi-channel access control strategy based on trust is designed to ensure that it can allocate channel resources on demand,efficiently and securely.The experiment shows that the average channel utilization rate of this technology is 99.7%,which can effectively cope with the network load change and complex user behavior,and the application effect is good.
