· ACS(Auto-Configuration Server,自动配置服务器)的参数,包括URL地址、用户名和密码。 · 服务提供商标识,CPE(Customer Premises Equipment,用户侧设备)从DHCP服务器获取该信息后,将该信息通告给ACS,以便ACS选择服务提供商特有的配置和参数等。CPE和ACS的详细介绍,请参见“网络管理和监控配置指导”中的“CWMP(TR-...
The DHCP server -- typically either a server or router -- is a networked device that runs on the DHCP service. The DHCP server holds IP addresses, as well as related information pertaining to configuration. The DHCP client is a device -- such as a computer or phone -- that connects to...
