摘　　要：随着中国社会信息技术和网络技术的快速发展,电信运营商将面临海量家庭网关产品的运维管理场景。文章基于IGMP原理,提出一种采用组播技术的家庭网关设备固件和XML配置升级的实用解决方案。详细介绍组播升级方案涉及的技术要点,并更新设计IGMP处理状态机,提供升级场景的配置及功能测试情况,为电信运营商平稳、快速地升级相应设备的软件版本和XML配置等运维管理工作,提供了有益借鉴。With the rapid development of Chinese information technology and network technology, telecom operators will face a challenge of operation and maintenance management of the massive home gateway products. Based on the principle of IGMP, this paper proposes a practical scheme which uses the multicast technology for the upgrade of the home gateway firmware and XML configuration. Also, it introduces the key technical points involved in multicast upgrade scheme in detail, updates the new design of IGMP protocol processing state machine, and provides the upgrading configuration steps and functional testing items. It is a useful reference for telecom operators to smoothly and quickly upgrade the firmware version and XML configuration of the appropriate devices in operation and maintenance management.
