Abstract: What is disclosed is a method having the first step of receiving, on a routing manager port address, a set of accounting request packets from a network access server having a network access server port address. Then, parsing the accounting request packet to derive a command flag and forwarding the set of accounting request packets to an authentication server, having an authentication server port address, over the authentication server port address. The method includes the further step of generating a set of routing table modification commands for a network router based on the command flag. What is also disclosed is an apparatus having a network access server, an authentication server coupled to the network access server, and a routing manager coupled to the network access server and the authentication server. The network access server has a network access server port address, the authentication server has an authentication server port address, and the routing manager has a routing manager port address. The routing manager is configured to: (1) receive, on the routing manager port address, a set of accounting request packets from the network access server port address; (2) parse the accounting request packet to derive a command flag; (3) forward the set of accounting request packets and to the authentication server port address; and (4) generate a set of routing table modification commands for a network router based on the command flag.

Abstract translation: 所公开的方法是具有第一步骤的方法，其在路由管理器端口地址上从具有网络访问服务器端口地址的网络访问服务器接收一组记帐请求分组。 然后，解析计费请求报文，得到命令标志，并通过认证服务器端口地址，将具有认证服务器端口地址的认证服务器转发给认证服务器。 该方法还包括基于该命令标志为网络路由器生成一组路由表修改命令的步骤。 还公开了一种具有网络接入服务器，耦合到网络接入服务器的认证服务器和耦合到网络接入服务器和认证服务器的路由管理器的设备。 网络接入服务器具有网络接入服务器端口地址，认证服务器具有认证服务器端口地址，路由管理器具有路由管理器端口地址。 路由管理器配置为：（1）在路由管理器端口地址上接收来自网络接入服务器端口地址的一组计费请求报文; （2）解析计费请求报文，得到命令标志; （3）转发会计请求报文集和认证服务器端口地址; 和（4）基于该命令标志生成针对网络路由器的一组路由表修改命令。
