摘　　要：随着宽带网络的普及和家居设备的数字化发展,高质量业务对家庭网络提出了较高的要求,而家庭网络的强异构性及缺乏面向融合业务开展的有效端到端QoS机制是其不利于开展高质量业务的主要问题。本文以高质量融合业务开展为驱动,首先从组网形式研究入手,确定可支撑包括高清视频应用在内的融合业务开展的组网方式,并构建出家庭网络的整体体系架构;在此之上,提出了基于业务区分的混合MAC机制,以及关键调度算法;最后对提出的机制的性能进行了建模分析。With the popularity of broadband networks and development of digital home equipments, high-quality service in the home network put a higher demand. However, the heterogeneous network and lack of effective integrated services oriented end-to-end QoS mechanism in home network are major problems to develop high-quality services. In this paper, driven by high-quality services integration, the networking methods is studied to identify a networking to support the integration of high-quality services including highdefinition video applications, and an overall architecture of home network is built. Above on this, an effective serviced-oriented hybrid MAC mechanism and its crucial scheduling algorithm are proposed. Finally, the performance model of on the mechanism is established and analyzed.
