    摘要： The present invention discloses a method of broadband access device for controlling a DHCP relay user, which method comprises modifying protocol fields in all of DHCP messages interacted between a DHCP relay and a DHCP client and a DHCP server during initiation phase of the DHCP interaction at Application Layer of TCP/IP protocol so that all of the DHCP messages interacted between the client and the server can pass through the DHCP relay. The present invention can easily control and manage the interaction between the DHCP client and the external DHCP server, vary the network parameters of the DHCP user and detecting the DHCP user online and so on according to the requirements of the user management strategy. Furthermore, the present invention only needs to process Application Layer of TCP/IP protocol to achieve the predetermined purpose of control/ management.

    摘要翻译： 本发明公开了一种用于控制DHCP中继用户的宽带接入设备的方法，该方法包括在应用中的DHCP交互的启动阶段，修改在DHCP中继与DHCP客户端和DHCP客户端之间交互的所有DHCP消息中的协议字段 TCP / IP协议层，使得客户端和服务器之间所有的DHCP消息交互都可以通过DHCP中继。 本发明可以根据用户管理策略的要求，轻松控制和管理DHCP客户端与外部DHCP服务器之间的交互，改变DHCP用户的网络参数，并在线检测DHCP用户等。 此外，本发明仅需要处理TCP / IP协议的应用层来实现预定的控制/管理目的。
