Cdma1x Vpdn Access Technology In The Enterprise

The VPDN (Virtual Private Dialup Networks) technology, which is based on the dialup customers, provides a specialized, secure solution to consolidate virtual networks and services. The technology exploits the IP networks' supporting function and takes advantage of the corresponding authentication and authorization.Rely on CDMA1X fast packet data network, we sets up a virtual private network of VPDN for enterprise to access Internat at a high speed, such as enterprise like bank ,government, public security, medical treatment and so on.This network is able to offer fast, safe , convenient special network for enterprise whenever and wherever possibly to visit. Not only it brings the reduction of the operation cost for enterprise's users .but also it brings the new point of growth of profit to the operator.According to Hunan UNICOM 's CDMA1X network current situation, the author has collected a great deal of demands for setting up enterprise's VPDN. After analysing and summing up those demans, the author finally has set up and put forward four kinds of safe , reliable , rational , feasible access technologies which is suitable for CDMA1X VPDN of enterprises of Hunan UNICOM .These access technologies are namely included about wireless common network access technology , long-distance private line access technology , private line connect to Internet for 165 access technology and wireless MPLS VPN access technology,and utilize these four kinds of access technologies for setting up access platform for enterprise using VPDN access to CDMA1X network of Hunan UNICOM. In this thesis,the author roundly compares four kinds of VPDN access technologies from six aspects such as protocol , security , enterprise gateway address , address assignment, access technology terms , roaming etc . At the same time the author writes some key configure into the text. In order to perfectly play a role in guiding to actual application for VPDN enterprise access , the author lists familiar wrong question and gives means how to solve the question . Simultaneity in Through some examples , the author tells how to realize VPDN access andsome configure in detail,and at the same time the author demonstrates the access process through visit interphase.At present, VPDN access application for hunan UNICOM has being changed to business experiment stage. In practical applications ,the author has found some security questions, so in this thesis the author has brought forword some corresponding solutions to solve security questions.
