【摘要】：隨著中國(guó)互聯(lián)網(wǎng)事業(yè)的迅速發(fā)展,中國(guó)的網(wǎng)民數(shù)量逐漸增多,位居世界前列。目前家庭網(wǎng)關(guān)是人們接入寬帶互聯(lián)網(wǎng)的最主要終端之一,也是各大互聯(lián)網(wǎng)運(yùn)營(yíng)商主推的互聯(lián)網(wǎng)接入設(shè)備。隨著網(wǎng)絡(luò)發(fā)展的日新月異以及眾多新業(yè)務(wù)的出現(xiàn),互聯(lián)網(wǎng)承載了越來越多的業(yè)務(wù),對(duì)保障這些業(yè)務(wù)的服務(wù)質(zhì)量的需求,給家庭網(wǎng)關(guān)的性能提出了更高的要求。為了滿足當(dāng)前時(shí)代背景下的家庭網(wǎng)絡(luò)需求,深入研究家庭網(wǎng)關(guān)的QoS功能顯得尤為重要。傳統(tǒng)的QOS功能僅粗略的通過對(duì)數(shù)據(jù)包的包頭進(jìn)行分類來區(qū)別配置調(diào)度策略,在現(xiàn)在業(yè)務(wù)類型眾多且復(fù)用端口嚴(yán)重的情況下,無法對(duì)業(yè)務(wù)進(jìn)行詳細(xì)區(qū)分,且對(duì)于一般家庭用戶而言配制方法復(fù)雜,無法得到較好的服務(wù)質(zhì)量。本文提出了一種基于用戶上網(wǎng)行為的家庭網(wǎng)關(guān)QOS功能,目的在于使家庭網(wǎng)關(guān)的QOS調(diào)度策略可以精確到業(yè)務(wù)類型,切實(shí)保障用戶真正需要保障的業(yè)務(wù)。其基本原理是基于DPI(深度包檢測(cè))技術(shù),設(shè)計(jì)出業(yè)務(wù)識(shí)別軟件模塊,對(duì)不同業(yè)務(wù)的數(shù)據(jù)包進(jìn)行不同的標(biāo)記,將高優(yōu)先級(jí)的業(yè)務(wù)類型放入高優(yōu)先級(jí)的隊(duì)列,確保重要業(yè)務(wù)的優(yōu)先保障。此外,互聯(lián)網(wǎng)運(yùn)營(yíng)商提供給家庭網(wǎng)關(guān)的上行帶寬通常是遠(yuǎn)小于下行帶寬,屬于稀缺資源。同時(shí)上行數(shù)據(jù)流的協(xié)議棧處理和轉(zhuǎn)發(fā)會(huì)占用大量的CPU資源，，開展數(shù)據(jù)加速方面的研究工作顯得尤為重要。本文將快速轉(zhuǎn)發(fā)技術(shù)結(jié)合到QOS模塊中,作為其擴(kuò)展體系,對(duì)于必要的關(guān)鍵業(yè)務(wù)進(jìn)行快速轉(zhuǎn)發(fā)處理,從性能上優(yōu)化上行數(shù)據(jù)流的處理和轉(zhuǎn)發(fā)以保障家庭網(wǎng)關(guān)的QOS質(zhì)量。本文還提出了一種QOS多級(jí)加速策略在家庭網(wǎng)關(guān)人機(jī)交互平臺(tái)的配置方法,設(shè)計(jì)了用戶空間配置的接口。家庭網(wǎng)關(guān)作為家庭內(nèi)部網(wǎng)絡(luò)與外部網(wǎng)絡(luò)的銜接,本文在傳統(tǒng)家庭網(wǎng)關(guān)基本功能的基礎(chǔ)上,實(shí)現(xiàn)了基于用戶上網(wǎng)行為對(duì)業(yè)務(wù)進(jìn)行區(qū)別調(diào)度和流量控制的功能,使家庭網(wǎng)絡(luò)內(nèi)部的多種業(yè)務(wù)都能正常工作,讓家庭用戶真正地暢想網(wǎng)絡(luò),擁有優(yōu)質(zhì)體驗(yàn)。
[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.
