Researchers Suggest P2P As Solution To Video Domination of The Internet

JPawlak writes "NewScientistTech reports that big businesses may be realizing the benefits of P2P technologies. Blizzard uses it to distribute patches for World of Warcraft, and now researchers at Microsoft are indicating internet users may have to use it to help distribute online video clips. The growing cost associated with delivering such content may be becoming prohibitive for some companies. 'The team also suggest a way to prevent Internet Service Providers' costs jumping when their users start uploading much more data. The trick is to allow sharing only between people with the same provider, when data transactions are free. That restriction would cut the pool of sharers into smaller groups, meaning MSN's servers would have to do more to fill any gaps in the service. But costs could still fall by more than half, simulations showed.'"

Re:The idea is great, but...

Browsers currently have absolutely no support for implementing anything like this.

Except for Opera, which is about the only program you actually need to interface with the entire web.

About the only thing it's not useful for is SSH and FTP.

I probably did not express my thoughts clear enough. Let's give it another go.

There are two portions to a P2P network - discovery and data fetch. Discovery determines where do you get your data from and fetch is the actual data flow. An ISP can confine a P2P service to its own network by either limiting discovery or by limiting the actual fetches.

The discovery is where the P2P networks lamely emulate a multicast application. They try to determine if a piece of data A is present in any of the surrounding nodes B,C,D,E,F. In order to do that they in the trivial case transmit to each node. In the more modern networks they transmit to hypernodes and get info from there. In either case they try to emulate a multicast network via a tunnel mesh (just the way people try to emulate Multicast on ATM LANE).

Compared to that a discovery mechanism based on multicast with a unicast reply can give you the information on where exactly is the piece which you are interested with one request. There is usually no need for hypernodes either. It just works. Magically. Further to this, you can set your discovery scope to find nodes which are 1,2,3...n hops away by tweaking TTL. Further to this, it is a true P2P network - totally serverless. If you throw in PKI authentication you can also make it as secure as you wish.
