中文摘要:针对动态网络优化依赖虚拟机在线迁移技术的问题,利用新型的网络架构SDN很好地实现了对网络设备的灵活管理和配置,达到数据中心虚拟化管理,且使得数据中心在资源优化,差错容忍和负载均衡方面具有很好的灵活性。同时,提出了一种基于QoS流机制的多路径虚拟机迁移策略(QMA),该机制通过对网络动态传输的虚拟机迁移资源划分为不同的QoS流,然后对每一个流选择有效的转发路径进行迁移,从而提高虚拟机整体迁移性能,最终达到对网络资源动态优化管理。

Research on Dynamic Network Optimization Based on SDN Network Architecture
Abstract:This paper makes use of the new network architecture SDN to realize the flexible management and configuration of the network equipment, to achieve the data center virtualization management, and make the data center in the resource optimization, error tolerance for the dynamic network optimization depends on the virtual machine online migration technology, And load balancing has a very good flexibility. At the same time, this paper proposes a multi-path virtual machine migration strategy (QMA) based on QoS mechanism, which divides virtual machine migration resources into different QoS flows by network dynamic transmission, and then selects valid forwarding for each flow Path to migrate, so as to improve the overall migration performance of virtual machines, and ultimately to the dynamic optimization of network resources management.
