随着物联网和互联网的进一步融合，家庭数字化服务逐渐增多，家庭网关的作用越来越突出，负载也越来越重。未来家庭环境中各式各样的数字化服务设备都需要连接互联网，例如个人电脑，数字电视，智能家电，可穿戴医疗设备等。家庭网络趋于复杂化，众多的网络应用之间相互影响，网络服务可靠性和网络服务质量逐渐被人们所关注。传统的家庭路由器和近几年新兴的物联网网关目前大多只专注于异构网络的互连互通和Internet的接入，并没有针对家庭网络服务质量做出系统的设计和实现。因此本文设计和实现了一种基于OpenWrt系统的家庭网络服务质量软件，使得家庭网络网络性能得到提升。服务质量（QoS）技术目前主要应用于IP网络中的骨干网和服务器上，无线WLAN的服务质量技术也是近年来的热点。而一般的家庭网络目前仍在提供“尽力而为”的服务，不仅对现有的网络应用没有QoS保障，而且也无法面对已经到来的物联网和云计算所带来的各种网络应用。本论文通过对未来家庭网络和家庭网关网络应用特点进行分析和阐述，结合Linux下的QoS技术，设计了物联网家庭网关QoS管理，并对QoS实现的效果进行了测试。围绕家庭网关的QoS研究、设计和测试，本文主要完成了以下工作：1.对IP网络的服务质量体系和技术进行了深入的分析和总结；2.分析家庭网络应用的网络特性，总结家庭网络现有的QoS问题，提出适合家庭网络的QoS方案。3.基于HTB（分层令牌桶）队列思想，对家庭网络业务进行分层分类。4.结合Linux内核的QoS实现技术，利用家庭网关的嵌入式特点，完成基于Linux内核的OpenWrt系统移植，并且在OpenWrt系统下，依据适合家庭网络的QoS方案，完成QoS软件的设计与实现。最后在实际的网络环境中进行了上下行带宽、网络时延和网络抖动等参数的实际测试。

With further integration of the Internet of Things(IoT) and the Internet, digital service in home gradually increased, home gateway make a more and more important role, however the load is becoming more and more heavy. In the future, a variety of digital devices need to connect to the Internet in our home, such as personal computers, digital TVs, smart appliances, wearable medical devices. Home networks become complicated. Numbers of network applications coexist in our home, but unfortunately not in a friendly way. Thus the reliability and Quality of Service(QoS) in the home networks have gradually been concern. Traditional routers and Internet of things which developing in recent years are currently only focus on the interconnection between heterogeneous networks and the Internet. The work that design and implementation for home network QoS haven’t been done in most home gateway.Therefore, we design and implement a home network QoS software which is based on OpenWrt system,then we have a improvement on our home network performence. Quality of Service(QoS) technology is currently used on the IP backbone network and servers, WLAN QoS technology is a research focus in recent years. And general home networks are still providing “best effort” service, it is not only no QoS guarantees on existing network applications, but also unable to face the challenges of variety of network applications that IoT and cloud computing brings. In this thesis, we analysis and exposition the characteristics of the future home networking and home gateway network applications, combined with Linux QoS technology, we finally make a design of QoS for IoT Home Gateway, and take a test on the real effect. When we focus on the QoS research on home gateway, we complete the following work:1. Making an in-depth analysis and summary on IP network QoS systems and technologies;2.Analysis the networking characteristics about home networking applications, make a summarize on the existing home network QoS problems, and finally approach an QoS scheme for home networks;3.We classified the home network applications based on HTB(hierarchical token bucket) queue.4.Combining the Linux kernel QoS implementation techniques, we complete the OpenWrt system porting. And we approach an QoS solution for home networking, work out the implementation with QoS software design. At last, a practical test was taken on the uplink/downlink bandwidth, network latency and jitter in the actual network environment.
