Abstract: This paper proposes a software defined virtual private network serving the massive data exchange of HEP（High Energy Physics）, and builds a software-defined network crossing different locations among the collaborative members of HEP experiments. An intelligent network route algorithm is also designed to exploit the ipv6 resources for HEP scientific data transfer. The algorithm also solves the network bandwidth problem between the collaborative members for the HEP experiments.

Key words: high-energy physics big data, software-defined networks, virtual private network, intelligent route
