How to organize and discover the virtual resource effectively is an important research issue in network virtualization environment especially across multiple infrastructure providers with conflicting goals. In this paper, we explore a virtual resource organization and discovery framework of multiple infrastructure providers. The framework composed of Cluster Index Servers and Management Nodes aggregates the virtual resources of multiple infrastructure providers based on the virtual resource's root attribute to implement the resource sharing and avoid blind searching to discover the required resources. In addition, this mechanism facilitates to discover the global optimal candidates rapidly and efficiently to complete the end-to-end virtual network embedding due to that each Cluster Index Server grasps a kind of specific virtual resources belonging to multiple infrastructure providers. This organization and discovery framework reduces search range and improves search efficiency for virtual networks provisioning from shared substrate resources greatly.
