A Study On The Technique And Method Of Unicom Wireless VPN Networking

The Author has taken part in the implementation of radio VPN network construction project for Union Communication Company. General summary and improved method of this project are given in this thesis. Many techniques and methods to construct a radio VPN network for Union Communication Company are discussed . First the technology utilizing MPLS and IPSEC encapsulation to construct VPN in the Internet is introduced. This technology is used to construct the Union Communication Radio VPN Network. It is shown by the implementation that this technology is very successful. Technology theories and application methods for radio VPN network construction are introduced. Based on the information security theory, the security problem of using MPLS and IPSEC to constructing VPN is discussed. Finally the solution of the security problem is mentioned.
