    • A method, correlative device and system for virtual network migration are provided. The method of the embodiments of the present invention includes: locating the source physical node in a region physical network; obtaining the virtual element corresponding to each virtual network in the source physical node and the state information of each physical node in the region physical network; determining, according to the virtual elements and the state information, a physical node that can implement the virtual network migration in the region physical network; reconstructing the mapping of each virtual network and the region physical network respectively in the physical node, comparing the mapping corresponding to each virtual network, and selecting the mapping with the least migration consumption as the mapping that implements the migration; sending, according to the mapping that implements the migration, a migration instruction to the physical node that needs to implement the virtual network migration. Furthermore, the embodiments of the present invention also provide the correlative device and system that implement the method.
    • 提供了一种用于虚拟网络迁移的方法,相关设备和系统。 本发明实施例的方法包括:将源物理节点定位在区域物理网络中; 获取对应于源物理节点中的每个虚拟网络的虚拟元素和区域物理网络中每个物理节点的状态信息; 根据虚拟元素和状态信息确定可以在区域物理网络中实现虚拟网络迁移的物理节点; 分别在物理节点中重构每个虚拟网络和区域物理网络的映射,比较与每个虚拟网络对应的映射,并选择具有最小迁移消耗的映射作为实现迁移的映射; 根据实现迁移的映射,发送到需要实现虚拟网络迁移的物理节点的迁移指令。 此外,本发明的实施例还提供了实现该方法的相关设备和系统。
