【摘要】：长庆通信处建设有长庆油田内部的宽带IP骨干网络,在网络内承载内数据、语音、视频等业务及其增值业务。随着中国互联网用户的快速发展,对上网速度要求高的用户也越来越高。特别是高清网络视频已经成为网民的重要应用之一,增长速度、覆盖范围不断提高。由于观看网络视频所需带宽的要求非常高,视频所面临的越来越多的用户,针对视频用户体验不佳所带来的问题,各大视频网站也都使用P2P加速软件,以充分占据管道提供的带宽资源。而在没有大量用户增长的情况下投入大量的资金,单纯的进行出口带宽的扩容以满足现有用户的需求,这又是运营商们不愿看到的。本文针对以上问题,研究P2P技术对网络出口造成的影响,重点分析了网络缓存技术在出口进行部署的可行性,并就华为iCache缓存系统工作流程进行了认真分析,并详细描述了华为iCache系统部署、实施、测试过程。部署后总体提升了长庆宽带用户体验,有效增加了流量收益,使得更精细化的流量经营成为可能。测试效果表明,系统回吐的实际流量要等于大于预期回吐流量,基本实现了流量经营的目的,达到了预期效果。
[Abstract]:The Changqing Communication Office has built a broadband IP backbone network in Changqing Oilfield, carrying data, voice, video and other services and value-added services in the network.With the rapid development of Internet users in China, users with high Internet speed are becoming more and more demanding.In particular, high-definition network video has become one of the most important applications for Internet users.Due to the very high requirement of bandwidth for watching the network video, more and more users are facing the video. In view of the problems caused by the poor video user experience, all the major video websites also use P2P accelerated software.To take full advantage of the bandwidth provided by the pipeline.And without a large number of user growth, the investment of a large number of funds, simply to expand the export bandwidth to meet the needs of existing users, which operators do not want to see.In view of the above problems, this paper studies the impact of P2P technology on network export, analyzes the feasibility of deploying network cache technology in export, and analyzes the workflow of Huawei iCache cache system.And describes the Huawei iCache system deployment, implementation, testing process in detail.After deployment, the broadband user experience of Changqing is improved, and traffic revenue is increased effectively, which makes more refined traffic management possible.The test results show that the actual flow of the system is equal to that of the expected flow, which basically realizes the purpose of flow management and achieves the expected effect.
