With the progress of the complex network research, it is found that the single network can not fully reflect the complexity and the diversity of the real network, and can not be used to depict and reveal the whole picture and the inherent law of the actual complex network. In the real world, there exist "networks of networks" or "supernetworks", with multi-levels and multi-dimensions, multi-attributes, multi-objects, interdependence, correlation and coupling characteristics, which become one of the most challenging frontier topics in the network science. This paper briefly reviews some research progresses of the supernetwork in recent years, with some results made by the network science group of China Institute of Atomic Energy in the research of multilayer supernetwork models and the top 500 enterprise High-Tech supernetwork. At present, the supernetwork research is just in its start step, and there are many unknown areas for us to explore.
