Abstract

Chinese universities use the multi-outgoing exports to solve the problem of the traffic of bandwidth to the Internet for the campus network, but the world wide web servers in the campus network might still be accessed very slowly by some users outside the campus network (from the public network). We discuss and analyze the reasons for slowly accessing to the campus network form the public networks and a novel solution for high-speed accessing to the campus network for the local client in public network is put forward. We first introduce an NAT (Network Address Translation) traversal approach based on reverse TCP (Transmission Control Protocol) connection, which has the advantage of not requiring any intermediary server. We test our NAT traversal approach in real network environment and the results show that it is effective. Meanwhile, we also test the network performance between the campus network and the local public network after the NAT Router between them has been traversed by our approach and the results show that the network performance by the second export accessing to the campus network is much better than by the campus network export.
