【摘要】：随着中国互联网事业的迅速发展,中国的网民数量逐渐增多,位居世界前列。目前家庭网关是人们接入宽带互联网的最主要终端之一,也是各大互联网运营商主推的互联网接入设备。随着网络发展的日新月异以及众多新业务的出现,互联网承载了越来越多的业务,对保障这些业务的服务质量的需求,给家庭网关的性能提出了更高的要求。为了满足当前时代背景下的家庭网络需求,深入研究家庭网关的QoS功能显得尤为重要。传统的QOS功能仅粗略的通过对数据包的包头进行分类来区别配置调度策略,在现在业务类型众多且复用端口严重的情况下,无法对业务进行详细区分,且对于一般家庭用户而言配制方法复杂,无法得到较好的服务质量。本文提出了一种基于用户上网行为的家庭网关QOS功能,目的在于使家庭网关的QOS调度策略可以精确到业务类型,切实保障用户真正需要保障的业务。其基本原理是基于DPI(深度包检测)技术,设计出业务识别软件模块,对不同业务的数据包进行不同的标记,将高优先级的业务类型放入高优先级的队列,确保重要业务的优先保障。此外,互联网运营商提供给家庭网关的上行带宽通常是远小于下行带宽,属于稀缺资源。同时上行数据流的协议栈处理和转发会占用大量的CPU资源，，开展数据加速方面的研究工作显得尤为重要。本文将快速转发技术结合到QOS模块中,作为其扩展体系,对于必要的关键业务进行快速转发处理,从性能上优化上行数据流的处理和转发以保障家庭网关的QOS质量。本文还提出了一种QOS多级加速策略在家庭网关人机交互平台的配置方法,设计了用户空间配置的接口。家庭网关作为家庭内部网络与外部网络的衔接,本文在传统家庭网关基本功能的基础上,实现了基于用户上网行为对业务进行区别调度和流量控制的功能,使家庭网络内部的多种业务都能正常工作,让家庭用户真正地畅想网络,拥有优质体验。
[Abstract]:With the rapid development of Internet in China, the number of Internet users in China has gradually increased, ranking the forefront of the world. At present, home gateway is one of the most important terminals for people to access broadband Internet. With the rapid development of the network and the emergence of many new services, the Internet carries more and more services. To ensure the quality of service of these services, the performance of the home gateway is required higher, in order to meet the needs of the home network under the background of the current era. It is very important to deeply study the QoS function of home gateway. The traditional QOS function only roughly classifies the packet header to distinguish the configuration scheduling policy. In the present situation of numerous service types and serious reuse ports, it is impossible to distinguish the services in detail, and the method of configuration is complex for the general household users. This paper proposes a home gateway QOS function based on user's Internet access behavior. The purpose of this function is to make the QOS scheduling policy of home gateway accurate to the service type. The basic principle is to design a service identification software module based on DPI (depth packet Detection) technology to mark the data packets of different services. Put the high-priority service types into the high-priority queue to ensure the priority of important services. In addition, the upstream bandwidth provided by Internet operators to the home gateway is usually much smaller than the downlink bandwidth. The protocol stack processing and forwarding of uplink data stream will consume a lot of CPU resources. It is very important to develop the research on data acceleration. In this paper, the fast forwarding technology is combined into QOS module, as its extension system, the necessary key services are processed quickly. In order to ensure the QOS quality of the home gateway, we optimize the processing and forwarding of the uplink data stream from the aspect of performance. This paper also proposes a configuration method of the QOS multi-level acceleration strategy in the human-computer interaction platform of the home gateway. The interface of user space configuration is designed. The home gateway is used as the connection between the home internal network and the external network. This paper is based on the basic functions of the traditional home gateway. It realizes the function of differentiated scheduling and flow control based on the user's behavior on the Internet, makes all kinds of services in the home network work normally, makes the family users really think about the network, and have the high quality experience.
