摘要
Xen是一个开放源代码虚拟机监视器,采用Xen虚拟化技术进行并行网络链路控制,提高并行网络联络的访问控制性能和安全性能,传统方法采用内存虚拟化技术进行并行网络链路调度,并行网络虚拟机特权级控制容易受到网络的漏洞攻击,导致链路吞吐性能不好。提出一种基于Xen虚拟化技术的并行网络链路控制算法。构建了基于Xen虚拟化技术的并行网络链路结构模型,在并行网络链路结构中进行开放源代码的特征量分析和TDMA协议构建,以此为基础采用多普勒频移方法进行并行网络链路控制算法改进。仿真结果表明,采用该方法进行并行网络链路控制,有效降低了数据传输的丢包率,提高链路吞吐量,提高了并行网络链路的安全性和吞吐能力。
Xen is an open source virtual machine monitor. The Xen virtualization technology is used toimprove the access control performance and security performance. The traditional method uses memoryvirtualization technology to carry out parallel network link scheduling. A parallel network link controlalgorithm based on Xen virtualization technology is proposed. A parallel network link structure modelbased on Xen virtualization technology is constructed, and the characteristics of open source code andTDMA protocol are constructed in the parallel network link structure, which is based on the Dopplerfrequency shift method. Simulation results show that the proposed method is effective in reducing thepacket loss rate of data transmission, improving the link throughput, and improving the security andthroughput of the parallel network.
