摘要：Du et al. put forward a solution to solve the slow access to the campus network. This solution offered a novel approach to complete NAT Traversal of the second export of the campus network and a good idea based on virtual private network (VPN) to realize the outer network can rapidly access the campus network with any application layer protocols, e.g., HTTP, FTP. A VPN solution based on UDP tunnel and Open VPN tap interface is designed and implemented to achieve above mentioned goal in this paper. We package the Open VPN Tap interface into a Dynamic Link Library (DLL) and program an VPN client and server in Java by calling our DLL API. Performance of the UDP-based VPN solution is evaluated and compared in a real network environment and between the campus network and the outer network. The results show that our solution is effective and can satisfy the actual requirements of network applications.
