摘 要

如今，越来越多人家里有电脑，有手机，所以越来越多的人愿意联网看视频，不再是电视，电影院，毕竟联网看视频能够暂停，能够重看等等。随着互联网的飞速发展，网络视频也在不断地发展普及，所以能够说互联网为视频网络提供了强大的市场动力，而视频网络的运用也是当代社会发展最主要的运用之一。在视频网络中，流式媒体是运用最广的技术，它的实时性强、可传载的数据量大。可是现今的互联网已经开始力不从心了，基于IPv4的互联网由于IP资起始的不足，存在各种问题，它已经没有办法满足当前社会的需要了，所以我们现在要一个新的网络架构来满足IPv4没有办法满足的高效的传载速度和效率和传载质量。论文将根据这一点，针对新一代网络协议IPv6对视频网络的运用进行科研探索。

随着技术的不停发展，IPv4已经逐渐开始不能适应时代的需求，为此IPv6被提出用来解决IPv4所不能解决的问题。IPv6有更广的地址数量、更快的报文处理速度，更好的QoS及更大的可拓展性。论文科研探索的是基于IPv6的组播技术，在IPv6地址编制中只有组播和单播，没有广播的概念。流式媒体技术需要优质的传载质量和传载效率，而组播形式能满足这两种需求。论文首先分析了当前时代国内外关于IPv6 协议的新特点的科研探索、IPv6 组播的运用与科研探索和流式媒体技术的科研探索。

本论文设计了一个基于IPv6的架构的视频网络传载系统，将用一台服务端上传网络视频，用IPv6的组播流对视频流进行传载，然后用一台客户端电脑接受并播放视频。这个视频流传载系统简单的模拟了当前IPv6协议在网络视频发展方面的趋势。

Design and implementation of a network video system based on IPv6

ABSTRACT

Nowadays, more and more people have computers at home, have a cell phone, watch video, so more and more people are willing to networking is no longer a television, cinema, look after all the networking video can pause, can to, and so on.With the rapid development of Internet, network video is in constant development, so the Internet provides a strong market power, video network and video network applications is also one of the major applications of modern social development.In video network, streaming media is the most widely used technology, its strong real-time performance, can transmit large amount of data.But today"s Internet already overstretched, based on the IPv4 Internet caused by a lack of IP resources, all kinds of problems, it has no way to meet the needs of the current society, so we are going to be a new network architecture to meet the IPv4 cannot satisfy the highly effective transmission rate and transmission quality.Paper will be based on this, for the next generation network protocol IPv6 to study the application of video network.

With the constant development of technology, IPv4 has gradually began to can not adapt to the demand of The Times, to be put forward to solve the IPv4 IPv6 can"t solve the problem.IPv6 has wider address space, message processing speed faster, better QoS and greater scalability.Paper research is based on IPv6 multicast technology, only in the IPv6 address establishment of multicast and unicast, no radio concept.Streaming media technology requires high quality transmission quality and transmission efficiency, and multicast form can meet the demand of the two.Paper first analyzes the current era at home and abroad research on new characteristics of IPv6 protocol, IPv6 multicast applications and research and streaming media technology research.

This thesis designed a video network transmission system based on architecture of IPv6, will use a server to upload video network, using IPv6 multicast stream of video transmission, and then use a client computer receives and broadcast video.The video streaming transmission system simple to simulate the trend with the development of the current IPv6 protocol in network video.

第一章 绪论

1.1 课题背景和科研探索意义

随着Internet的发展与普及，IPv4网络协议在设计上的局限性和不易拓展性正在渐渐地显现出来，面对当前社会的各式需求，例如网络视频会议，大规模的视频网站，当前很火的网络直播，远程视频课程，网络电台等等，这类运用已经融入到了我们的日常生活中，成为当代社会的基本需求了，IPv4的局限性让它没办法满足人们的这类需求。而这类运用给人们的生活带来的方便和实惠是跨时代性的，这也让网络成为现代社会发展的最基本的要求之一。网络也不再只是简单的数据报文传载，它还携带着大量的图像，声音，视频的传载，IPv4已经不足以满足这类要求了，在这样的情况下，IPv6被引进了当今网络架构，逐渐替代IPv4。
