[Abstract]:With the development and wide application of cloud computing technology, especially IaaS (Infrastructure as a Service), cloud computing platform can easily manage the computing, storage and network resources it owns. Virtualization technology is the key technology to encapsulate the underlying resources. Computing resource virtualization and storage resource virtualization have developed very mature. However, virtualization of network resources is the weak link of virtualization technology at present. As the most mainstream SDN (Software defined Network) implementation method, OpenFlow technology has completely changed the traditional closed network architecture. It provides a new solution for the implementation of network virtualization. The combination of cloud computing platform and OpenFlow technology can provide users with virtualized network topology. Cloud computing platforms generally provide dynamic migration of virtual machine resources, but after cloud computing platforms introduced OpenFlow to implement network virtualization, For the new problems such as the dynamic migration of network resources and the dynamic migration of virtual machines on the network topology, the traditional dynamic migration methods can not be directly used to solve these problems, so this paper designs a resource dynamic migration system to solve these problems. The system not only provides the virtual machine resources of the traditional cloud computing platform, but also provides the virtualized network topology directly to the user. Ordinary users of the system do not need to care about the implementation of the underlying resources. After the system administrators dynamically migrate the location of the system resources, the topology provided by the system to the users remains unchanged. On the basis of OpenStack, the system introduces OpenFlow technology, uses OpenFlow switch to realize virtualization network devices, and then uses the stream table of OpenFlow to isolate the logical network topology and ensures that the dynamic migration operation will not affect the topology. The system provides easy to use Web front-end and administrator dynamic migration tools.
