最近看的几个开源项目的印象

不是专业的评价,就像读书笔记吧:

1、Azureus(http://azureus.sourceforge.net):这是java版的betorrent,最新版本2.4.0.2。从网上直接下载的源代码是没法构建的,所用的库没有在包里面。可以到:http://azureus.cvs.sourceforge.net/azureus/这个地方去找。对我们研究的意义主要在于参考其算法。

2、Shareaza(http://www.shareaza.com/):这是C++版的,他最大特点就是集成了对多个流行P2P文件格式的支持,有了它可以下载电驴、.torrent等,目前版本是2.2.1.0。对: EDonkey2000GnutellaBitTorrent 及Gnutella2 (G2) 都支持,界面也很酷,支持换肤。大家可以直接下载源代码构建(ide环境是.net)。

3、icecast(http://www.icecast.org):给人感觉比较简单,主要实现了对mp3的网络播放,可用于构建网络电台。

4、P2P Networking Theory(http://cis.poly.edu/~ross/p2pTheory/):这是几个大学的一些P2P领域的学者一起搞得,叫:P2P Networking理论,我觉得最大的价值是,在上面可以找到一些论文。

5、theora(http://www.theora.org/):就目前了解来看,他是干了这么一件事情:“Free Video Compression ”即:免费的视频压缩算法,可以下载库文件(c写的),目前支持:“A year after getting import and export support for theora, Cinelerra now has distributed theora encoding support, which makes theora content creation much faster.”即:对分布式编码有支持,这是很有意义的。

6、PeerCast(http://www.peercast.org/):“PeerCast is a simple, free way to listen to radio and watch video on the Internet. It uses P2P technology to let anyone become a broadcaster without the costs of traditional streaming. This means you get to hear and watch stations not normally found on commercially funded sites. ”简单的讲,就是一个p2p的可以用于网络电台的流媒体软件。能够穿越防火墙、Nat等。源代码获取,需要使用“Subversion”(这个东西设计出来是替换cvs的,确实不错,有空研究下,可以到“http://www.subversion.org.cn/svnbook/”看使用说明),地址:svn://peercast.org/peercast/tags(好像要选择下,不然会搞下来好几个版本的代码),也可以找我要。

7、FreeCast(http://www.freecast.org/): “FreeCast is a Java application which allows peer-to-peer streaming. It makes possible a stream broadcast to a large number of listeners from a simple DSL connection.”java编写的P2P在流媒体的应用,下载:http://download.freecast.org/,有源代码,可以研究研究。

8、ActlabTV(http://actlab.tv/):这个页面有介绍http://actlab.tv/technology.htm

9、TrevBus(http://www.trevbus.org):是作者在做工程学位论文时开发的,“Trevbus will enable content streamers and others to pool their unused bandwidth so content streams can be sent to a large audience”。软件需求说明:http://www.trevbus.org/SRS.html,软件设计文档:http://www.trevbus.org/SDD.html,理论基础?:http://www.trevbus.org/thesis.html

10、Stream2Stream(http://s2s.sourceforge.net/):java语言开发的P2P流媒体系统,“Stream-2-Stream implements multicast+, a next generation streaming protocol. Multicast+ is more efficient and requires less bandwidth than direct streaming (e.g. shoutcast/icecast). Stream-2-Stream (abbreviated "s2s" or "S2S") stations have no user limit; stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another through multicast and unicast p2p, rather than everyone getting a stream from one central server (Shoutcast/Icecast). ”更多:http://s2s.sourceforge.net/about.php

11、P2Pradio(http://p2p-radio.sourceforge.net):java语言开发的P2P音视频服务和客户端系统,“P2P-Radio can distribute audio streams in the MP3 and Ogg Vorbis formats and video streams in the NSV format over the Internet. This is done in a peer-to-peer way. The broadcaster doesn't need to send the stream to every single listener, because the listeners distribute it among themselves.”,好像用于学习很不错,好像是学生的一个学期论文。详细介绍:http://p2p-radio.sourceforge.net/about.php.en

12、Nodezilla(http://evl.sourceforge.net:这是一个由java编写的安全的、分布的并且高容错的路由系统。他的主要目标就是,为分布式应用(聊天、高清晰视频多播、文件共享、安全文件存储)提供底层。目前构建的应用有:Anonymous File sharingHierarchical Multimedia StreamingDigital photo sharing with selected friendsDistributed BitTorrentStore DatabaseUser driven storage/retrieval of objects. 详细请见:http://evl.sourceforge.net/whatis.html#whatis
