摘要
针对网络资源分配受到时延影响,导致分配丢包率较高的问题,提出关于虚拟云技术的网络资源动态分配系统设计。通过逻辑虚拟网络片,对网络中节点和链接进行合理配置。设计消息拦截与解析模块,将不匹配的信息传输给开源控制器,开源控制器通过API接口按照各自权限进行资源分配。计算时隙窗口间隔,配置网络资源动态分配时隙申请机制,并通过信道实时发送预约信息。根据主从站时隙申请过程,结合虚拟云技术设计网络资源动态分配流程。由实验结果可知:该系统最短时延为120 ms,最低丢包率为3%,具有良好的网络资源动态分配效果。
The network resource allocation is affected by time delay,which results in high packet loss rate.In view of this,a design of network resource dynamic allocation system based on virtual cloud technology is put forward.The nodes and links in the network are configured reasonably by the logical virtual network slice.The message interception and analysis module is designed to transmit mismatched information to an open source controller.The open source controller is used to allocate resources by API(application program interface)according to their own permissions.The time slot window interval is calculated.The time slot application mechanism for network resource dynamic allocation is configured.The reserved information is sent by the channel in real time.According to the time slot application process of master station and slave station,the dynamic allocation process of network resources is designed in combination with the virtual cloud technology.The experimental results show that the shortest delay of the system is 120 ms and its lowest packet loss rate is 3%,so the system has a good effect of dynamic allocation of network resources.
