METHOD AND DEVICE FOR CREATING VIRTUAL NETWORK INSTANCE

摘要

The present invention relates to the field of electronic information. Disclosed is a method for creating a virtual network instance, which can solve the problem that when multiple paths between internal virtual network units in a network service are available for data, the failure of determining one of the paths for transmission causes service interruption. The specific solution is: acquiring network service descriptive information; using virtual network units with expected instance creation as virtual network units with expected instance creation according to the network service descriptive information; sending resource requirement information and connection information of the virtual network units with expected instance creation to a lower-layer device; sending path information to a network device of the lower-layer device, or sending the path information to each of the virtual network units; and selecting a transmission path according to the path information when data is under transmission between the virtual network units. The present invention is applied to creation of a virtual network instance.
