Winny developer is a technical advisor P2P system "SkeedCast"

It seems that it is a secure P2P mass content distribution system that Mr. Ishi Kaneko 47 Mr. Winny developers was in charge of development advisor. The point that it is possible to deliver by setting conditions as desired by the content holder, such as paying, free, setting the number of times of play and deadline, restricting copying. It is the opposite of Winny now.

Pilot operation starts from May, full-scale service start from August.

Mr. Winny developer 47 Mr. Isamu Kaneko's comments are as follows.

I am in charge of development development of "SecureP2P" out of "SkeedTech" this time. The current content distribution is mainly C / S type (client server type) where access is concentrated on a specific server, but this is too suited for efficiently distributing large capacity contents because the load is concentrated too much Is not ... Based on P2P with excellent load balancing, SkeedTech built secure P2P by combining know-how gained by the previous verification experiments and newly developed network management functions. While Japan has outstanding internet infrastructure among developed countries, it is hard to say that Japan can fully utilize its capabilities. We are convinced that the newly created SecureP2P will deliver content delivery to a new era for content distribution.

The core technology of this "SkeedCast" is "SkeedTech", which is a server side P2P system. This infrastructure is provided by IIJ. Patent pending and application number is 2005-276239. Using this "SkeedTech", Windows Media DRM (digital rights management technology) can be added. It seems to be considering everything such as secure or content distribution side, this is.

It is also a point to use an existing site to deliver. A downloading side uses a tool made in Flash called "contents navigator" to download it. It seems that the way to make this "contents navigator" is going to be open.

The future usage model looks like the figure below. It is quite a merit from the viewpoint of enterprises that it is possible to significantly reduce the additional investment at a low cost when it is desired to distribute large-capacity contents, and since the downloading speed should be comfortable from the user's point of view, this merit You can enjoy.



In short, the server side is P2P technology, the download side can use the usual style as before and there is no need to install something new. Also, content to be delivered can be strictly managed and a billing model can be built so flexible operation is possible. If you do not see how it feels in the test run in May, I can not say it, but I feel like I can expect it. It is not very new, but there may be room for acceptance.
