湖南铁通计费系统的若干技术研究

路由器互联端口运用安全策略,有效拦截病毒的传播;在网关路由器、三层交换机上实行ARPA绑定,瓦解ARP病毒的攻击,实用效果良好。在计费UNIX主机上编写的程序,查出实时采集丢失的原始话单,保证原始话单无损到达计费系统,带来的经济效益显著。

This paper discussed an effective way to head off virus spread by security policies through router ports of interconneetion and collapsing ARP virus attacks by ARPA binding in gateway routers and third tier switches with good practical effects. The author introduces the program developed independently in UNIX accounting host, which can search out lost real-time-collecting bills, ensuring original bills can be transmitted to the accounting system for billing without loss, and an obvious financial profit can be re- ceived.
