Network virtualization allows the flexible sharing of physical networking resources by multiple users (tenants). Each tenant runs its own applications over its virtual network. OpenVirteX, a network virtualization platform, provides virtual Software Defined Networks (vSDNs). Each vSDN is customizable in terms of topology as well as addressing scheme. However, the virtual network mapping process of OpenVirteX does not take into account resource constraints and deployment cost, just to complete the virtual network mapping. To solve this problem, this paper proposes to deploy the classic mapping algorithm named Improved-vnmFlib on the OpenVirteX platform and designs the overall process of implementation. Finally, we build a complete simulation environment to test the new platform, the test results show that the new platform can take a virtual network mapping combined with the deployment cost under the premise of resource constraints, and can create the virtual network automatically according to the mapping result.
