Abstract: Network virtualization is essentially a resource sharing technology. In network virtualization environment, all kinds of substrate network resource were abstracted as logical network resource, so as to realize the flexible matching of resources and traffic demand. Resource description and discovery is the basis of matching. A hierarchical domain resource management framework was proposed. On this basis of it, a virtual network resource description and discovery mechanism based on OWL was given out. Thus, an effective new way is provided for virtual network resource description and discovery.
