【摘要】：目前,四川铁通互联网宽带运营主要由三部分组成,即容器(宽带端口速率和承载通道),包装(营销策划-价值、精品宽带等)和内容(互联网流量)。其中,互联网流量是用户得到的实质,也是四川铁通销售宽带产品给用户的核心实质。在互联网流量方面,基于缓存的互联网内容平台建设是新兴课题,是ISP互联网优化工作的重要内容,往往涉及到较大投资和工作量。在当前的用户满意度提升活动中,对于提高用户满意度而言,业务的价格折扣和商业宣传已不是决定因素,而感知质量的体验越来越重要。掌握了互联网内容就掌握了用户的需要。本研究主要目的在于提升互联网内容的供出和服务。在分析国内外主流缓存技术发展趋势的基础上,结合四川铁通公司实际网络和投资情况,研究了基于缓存的互联网内容平台在四川铁通网内的部署,主要内容包括:1.研究了基于缓存技术的各类主流平台的内容发布方式,并根据对各类平台特性的研究,针对后期不同类型应用场景,提出了相适应的解决方案,以适应公司平台建设及业务发展的需求。2.研究了主流缓存内容平台的发布、检测、监控、管理四种主流技术。现代缓存技术通过对P2P Peer种子的重排和对P2P资源的缓存,能实现对P2P流量的高度本地化。通过对热点应用视频及文件的实时动态搜索与发现,从技术上减轻网络承载用户对网络之间的不同流量需求。在减少对Internet互联网出口流量需要的同时,通过缓存于不同地域之间的更多内容源,大幅提升用户感知质量。3.分析了目前四川铁通核心网的现状和问题,提出了相适应的改造和优化方案,以确保基于缓存的互联网平台能顺利实施。针对四川铁通现有网络情况,对网络结构进行相关调整和重构,以10G大颗粒带宽替换原有小颗粒传输单元。使集中的流量监控设备能100%全覆盖监控网络的应用情况。选择有优势的承载路由协议,提高了核心网承载能力和转发效率。4.提出了不同构架方式的缓存技术方案,在确保网络拓扑不受影响的同时,实现了灵活的网络建设。通过服务器、服务器群之间的松连接架构,保证了四川铁通能在现有网络流量增长模型下,可进行灵活的网络扩容,而不影响在网运行的所有业务。于此同时,又可以对Internet互联网网络内容平台的管理控制、缓存工作、流量疏导以及综合管理和运营实现中央集中化管理。
[Abstract]:At present, the broadband operation of Sichuan Tietong Internet mainly consists of three parts: container (broadband port rate and carrying channel), packaging (marketing planning-value, boutique broadband, etc.) and content (Internet traffic). Among them, the Internet traffic is the essence that the user obtains, also is the core substance that Sichuan Railcom sells the broadband product to the user. In the aspect of Internet traffic, the construction of Internet content platform based on cache is a new topic, which is an important part of ISP Internet optimization, and often involves a large amount of investment and workload. In the current user satisfaction promotion activities, to improve customer satisfaction, the price discount and commercial promotion of business is no longer the decisive factor, but the experience of perceived quality is becoming more and more important. Master the content of the Internet to master the needs of users. The main purpose of this study is to improve the Internet content supply and service. On the basis of analyzing the development trend of mainstream cache technology at home and abroad, combined with the actual network and investment situation of Sichuan Railcom Company, this paper studies the deployment of Cache based Internet content platform in Sichuan Railcom Network, the main contents of which include: 1. This paper studies the content distribution methods of all kinds of mainstream platforms based on cache technology, and according to the research on the characteristics of various platforms, puts forward a suitable solution for different application scenarios in the later period. To meet the company platform construction and business development needs. 2. This paper studies the four main technologies of publishing, detecting, monitoring and managing the main cache content platform. Modern caching technology can achieve high localization of P2P traffic by rearranging P2P peer seeds and caching P2P resources. Through the real-time dynamic search and discovery of hot application video and files, the different traffic requirements of network bearer users are alleviated technically. At the same time, it can greatly improve the perceived quality of users by caching more content sources between different regions while reducing the need for Internet export traffic. This paper analyzes the present situation and problems of Sichuan Tietong core network, and puts forward a suitable transformation and optimization scheme to ensure the smooth implementation of the cache based Internet platform. In view of the existing network situation of Sichuan Railcom, the network structure is adjusted and reconstructed, and the original small particle transmission unit is replaced by 10G large particle bandwidth. Make centralized flow monitoring equipment 100% full coverage of monitoring network applications. With the advantage of bearer routing protocol, the load carrying capacity and forwarding efficiency of core network are improved. 4. A cache technology scheme with different architectures is proposed to ensure that the network topology is not affected, and the flexible network construction is realized at the same time. Through the loose connection structure between server and server cluster, it is ensured that Sichuan Tietong can carry out flexible network expansion under the existing network traffic growth model without affecting all the services running on the network. At the same time, it can realize the centralized management of Internet content platform, such as the management and control of Internet network content platform, the work of cache, the traffic diversion, and the integrated management and operation.
