摘要： 针对原有宽带接入方式缺少安全认证和审计、容易遭受网络攻击等不足，提出一个安全宽带接入方案，建立安全宽带接入系统，包括基于双ISP的接入系统、PPPoE+RADIUS认证系统以及基于JSP的宽带查询系统。应用结果证明，该系统能有效提高宽带接入的安全性和可靠性。

Abstract: The existing inadequacies of CTBT beijing NDC broadband access system is analyzed in this paper, such as no authentication and audit, being susceptible to network attacks and so on. A new security broadband access solution is designed. The security broadband access system is set up, including dual ISP access, PPPOE+RADIUS access authentication system and query system based on JSP are realized. The system’s security, availability, reliability are proved in application.

Key words: Network Address Translation(NAT), Point-to-Point Protocol(PPP), Point-to-Point Protocol over Ethernet(PPPoE), Remote Authentication Dial in User Service(RADIUS) protocol, Traffic Controller(TC), security broadband access
