With the popularization of informatization, the topic of “Digital Home Networks” is hotter talking. Under this background, Zhejiang Telecom launched to exploring home gateway system. The writer took part in the trainings of exploitation and test of home gateway when she worked for the project of Home gateway exploitation in the Zhejiang Public Information Industry Co., Ltd. From that, she analyzed home networking and home gateway which is the core device of home networks. Then analyzed and designed the QoS technology of home networks combined with QoS technology of computer networks. First, this dissertation introduces the conception of QoS, and analyzed and compared QoS technology in the computer networks also contains the advantage and disadvantage of each technology. For that, we selected Diff-Serv. Second, it analyzed the home networks and home gateway and the function requirement of QoS in home networks. Third, integrating QoS requirement in home networks with the existing QoS technology, it raises the problems on the design of QoS in the home networks and provides the solutions of the problems. At the last, it provides the developing foreground of home networks, the development of QoS technology and the QoS in the home networks perfection with the increasing of people needed for life and entertainment.
