再见P2P,P4P来了

ISPs(Internet service providers,网络服务提供商)似乎天生仇视P2P(peer to peer)软件,因为大量的影音文件在网络上传输,加大了ISPs的负担。因此才有comscore这样的运营商限制甚至阻止P2P软件使用的情况,被美国通讯委员会(FCC)调查,并且很可能面临重罚。

对抗不是办法,那么只有合作。Verizon公司想出的办法是和P2P软件制造者合作研发,尽量减低大文件传输对网络的压力,他们合作的工作组成为P4P。

P4P主要是解决什么问题呢?P2P传输是在用户之间进行,同时上传和下载。但是它存在着这样一个问题,由于用户使随机分配,所以很可能美国用户在上传的文件是由德国用户在下载,而德国用户上传的文件是中国用户在下载。这种长距离的文件传输,不仅加剧了网络负担,也导致下载的速度变慢。

Verizon则把网络架构的细节和P2P软件制造商分享,制造出一款尽量降低这种国际间分享的行为,优先在附近用户之间进行。新的P2P软件取得了效果,测试中58%的资料传输在Verizon的用户之间进行,而传统方式只有6.3%。同时,用户下载速度平均提高了60%。

实验用的软件叫作Pando,NBC即将推出的高清电视剧免费下载将通过这种软件进行。P4P技术很可能在4月在Verizon的网络中进行全面推广。P4P工作组的成员还包括AT&T。

更新:关于P4P的研究,一位读者留下了极有价值的信息,具体请大家看下面的留言。

Verizon gets cozy with P2P file-sharers

(via Y!news via AP) Peer-to-peer file sharing, the primary vehicle for online piracy, has been as unpopular with Internet service providers as it has been popular with users.

Providers have banned, blocked or slowed peer-to-peer traffic in their efforts to keep the flood of music, video, games and software from overwhelming their networks. But Verizon Communications Inc. has broken ranks with the industry and announced Friday that it plans to help its users share files faster. Read more.

Comcast接到FCC正式调查函——美国ISP着手另类网络内容审查(二)

Comcast公司周一宣布,已经正式接到美国通讯委员会(FCC)的调查函,该公司涉嫌严重干涉其宽带用户的使用某种特定的网络文件传输方式(P2P)。事件的详细起因请看之前的报道“美国ISP着手另类网络内容审查”。

很多公司由于同样使用P2P方式传输文件,也受到了Comcast的限制。一家叫Vuze的公司单独向FCC提起诉讼,希望FCC能够澄清,网络服务提供商(ISP)到底有多大权限控制用户的流量。

更新:经过FCC几次听证之后,3月27日,Comcast和BitTorrent两家公司签订了互谅协议,互相协作,更有效的解决富媒体文件传输问题和网络空间容量管理。Comcast不再对来自BitTorrent的流量进行限制。

此事到此显然还没有结束,因为这只是这两家公司之间的行为,更大的命题在于网络中立的原则能否确认,甚至立法加以保障。

FCC asks Comcast about Internet filter

(via Yahoo!news reported by AP)

Comcast Corp. Monday said it has received letters of inquiry from the Federal Communications Commission regarding complaints that the company actively interferes with its subscribers’ Internet traffic.

A coalition of consumer groups and legal scholars asked the agency in November to stop Comcast from discriminating against the sharing of certain types of Internet data among subscribers. Read more.

Update: Comcast Corporation and BitTorrent, Inc. announced today that they will undertake a collaborative effort with one another and with the broader Internet and ISP community to more effectively address issues associated with  rich media content and network capacity management. While BitTorrent and Comcast are talking directly, they are also in discussions with other parties to help facilitate a broader dialogue and cooperation across industries. Read more.

BT不死

BT(bit torrent)的恶名来自于盗版,甚至在有些人眼里,BT是盗版的代名词。
BT几乎是每个网民都用过的搜索和下载工具,难道我们使用过的人都成了强盗?显然不是。BT本质上是一种p2p工具(peer to peer),体现的是一种分享的p2p精神。
BT的内容来自于个人,他的最终目的也是个人。这就好像我有一把漂亮的小刀,然后我把他拿给朋友们看。原来我只是拿给一个人看,现在却有很多人一块儿看。他们都从我的分享行为中得到了乐趣。
这怎么能同盗版等同起来呢?这就好比我的那把漂亮的小刀在递给朋友时,突然被强盗抢走了,然后强盗用这把小刀刺伤了人。难道因此我和我的朋友就都成了强盗?
显然不是,分享是没有错的,有错的是利用别人的分享行为来犯罪的人,比如那些依靠盗版牟利的人。
Demonoid这个全球第二大的BT搜索平台,其位于加拿大的服务器被关停了。而服务器提供商的压力正是来自于加拿大音像工业协会(Canadian Recording Industry Association ,CRIA)。

Suprnova也曾遭受过服务器被关停的事情,不过现在,他又回来了。
拔掉服务器的电缆不会起到任何作用,相反,现在提供免费音像服务的公司(包括fox,nbc这样的大公司)越来越多,这些公司找到了不同的盈利模式(大多数是用流量吸引广告),因此愿意向用户提供免费服务。那些喜欢拔电缆的人,是否也要把他们的电缆都拔掉?
解决问题的办法归根结底有两个:要么把所有的强盗都抓起来;要么寻找新的盈利模式。

BT Never Die 

“The CRIA threatened the company renting the servers to us, and because of this it is not possible to keep the site online. Sorry for the inconvenience and thanks for your understanding.”

This is the statement coming from Demonoid, the world second largest tracker online. The isp pulled out the plug by being pressured from CRIA(Canadian Recording Industry Association).

BT is thought of the origin of pirate by the recording industry.But the nature of BT is a spirit of P2P–share. You have something good and you want your friend watch it, the content is coming from person and go to the other person.

The pirate is not the mistake of BT, but people who use it to get commercial benefit.

Today some representative of the record industry has changed their mind. Now they allow the user to enjoy for free with ad-supported content.

What the record industry should do to against the pirate one is catching all the bad people, another is to change the benefit module.
