利用网关将互联网协议地址分配给共享子集中的客户端设备

Utilizing a gateway for the assignment of internet protocol addresses to client devices in a shared subset
Abstract:
A gateway may be utilized to assign Internet protocol (IP) addresses to client devices in a shared subnet. The gateway may include a dynamic host protocol configuration (DHCP) proxy server. The proxy server may receive discover messages from the client devices. The proxy server may send proxy discover messages to a master DHCP server and receive offer messages containing IP addresses and local options. The proxy server may add/modify the local options to create proxy offer messages, send the proxy offer messages to the client devices and receive IP address request messages from the client devices. The proxy server may send proxy IP address request messages to the master DHCP server and receive acknowledgement messages. The proxy server may add/modify local options in the acknowledgement messages to create proxy acknowledgement messages and send the proxy acknowledgement messages to the client devices to assign the IP addresses and the local options.
Abstract(Chinese):

可以使用网关来将共享子网中的因特网协议（IP）地址分配给客户端设备。 网关可以包括动态主机协议配置（DHCP）代理服务器。 代理服务器可以从客户端设备接收发现消息。 代理服务器可以向主DHCP服务器发送代理发现消息，并接收包含IP地址和本地选项的报价消息。 代理服务器可以添加/修改本地选项以创建代理报价消息，向客户端设备发送代理报价消息，并从客户端设备接收IP地址请求消息。 代理服务器可以向主DHCP服务器发送代理IP地址请求消息，并接收确认消息。 代理服务器可以在确认消息中添加/修改本地选项以创建代理确认消息，并将代理确认消息发送给客户端设备以分配IP地址和本地选项。
