Claim Text:
1. An inter-domain virtual network mapping method, performed by a server of a virtual network provider and comprising: receiving an inter-domain virtual network request; obtaining a latest physical network architecture information of each of N network domains; calculating an optimized mapping solution according to the latest physical network architecture information of the N network domains to divide an inter-domain virtual network into N virtual sub-networks, each virtual sub-network corresponding to one of the N network domains, the optimized mapping solution making a sum of a mapping price of all virtual nodes of the inter-domain virtual network and a mapping price of all virtual links of the inter-domain virtual network minimum; sending each virtual sub-network to a corresponding network domain thereof and performing a mapping in each network domain; initializing SUM=0, traversing each network domain and receiving a result of the mapping in each network domain, and updating SUM according to the result of the mapping in each network domain, determining whether SUM is equal to N; if yes, instructing each network domain to distribute a physical network source for the inter-domain virtual network request; and if no, instructing each network domain to maintain current status.
