The Design And Practice Of Vpdn Authentication Platform

In a traditional network connection, the field staff need to travel from the company headquarters extract some important information about customers, in general, can only use MODEM to dial-up connection into the company's Intranet, using Telnet, FTP or other network services to obtain information.These interconnect expensive, businesses must afford the expensive long-distance phone charges, while the security of customer information without strong assurance that the process easy to be intercepted in transit, and these data also cannot be placed on WWW and other unsafe places.In this case, if we adopt the VPDN (virtual private network dial-up) of the network model can be a good solution to this problem, traveling employees to use local ISP can provide VPN services and the company's enterprise routers (also known as the VPN gateway) establish the private tunnel connection, RADIUS server can authenticate and authorize staff to ensure the security of the connection at the same time greatly reduce the burden of the cost of telephone, data transmission has become a new generation of business applications development.With the 3G network construction, from the development of mobile communication direction, the future of mobile data services will be the mainstream of development and focus, enhance the transmission bandwidth wireless network to further promote the development of wireless VPDN technology. This article focuses on fixed-based broadband, GPRS/WCDMA the VPDN service implementations, using L2TP tunneling protocol and GRS, the transmission of data encryption package, to meet the business users of wireless transmission of data integrity, security, confidentiality requirements, and the corresponding access management platform for comprehensive certification program. By discussing the comprehensive (broadband, GPRS/WCDMA) VPDN authentication platform to build the business to achieve the same platform VPDN users of broadband, wireless VPDN user authentication, authorization and accounting.Improve the utilization of existing equipment to achieve the unified planning and construction, unified management purposes. VPDN user in order to achieve a smooth transfer of the original network, reducing network delivery of telecom industry restructuring C resources brought by the loss of customers.Chongqing, China Unicom is currently based on GPRS/WCDMA the VPDN enterprise-class access business is transferred to the operational test phase, the existing enterprise access are created through the project implementation VPDN access platform. Business promotion from now on the situation, the platform can meet the needs of business development, enterprise groups to meet the needs of a variety of access methods, bringing a good social and economic benefits, has become a continuation of mobile data value-added services of a research direction.
