With the new emergence of the 4th generation of peer to peer file sharing networks, there are many new capabilities to make your file sharing a more adventurous. For example, not only can the 4th generation of peer to peer file sharing clients still operate in the old fashion to allow you to download almost any type of file, but you can also live stream.

Let’s take a look at the live streaming aspects of the 4th generation of peer to peer file sharing clients. Let’s say that everyday, you favorite television show comes on at the same time. No let’s continue with this hypothetical scenario. Let’s also say, that around the world, there are many others who love that same television show, but can no longer get it on their television in their area. You can then simply plug your cable into that unused video input card, and simply stream that television show around the world with simplicity and ease thanks to the 4th generation of peer to peer file sharing clients. To take it a step further, you could run the output of your stereo into the input on the soundcard of you computer and stream your favorite radio station.

Now I am in no way condoning the use of the peer to peer file sharing protocols for illegal purposes, but as a hypothetical situation, I have included these basically as an example for you. The people on the other end, could then tune into these streams just like watching a TV channel or tuning in a radio station on their home receiver.

The concepts of tree structures no longer exist in the 4th generation of peer to peer file sharing networks, as they have all converted over to the bit torrent network’s style of swarm structures in the file sharing networks. This makes the ease of sharing simpler and more cross compatible.

But the question now is, “what client should you choose?” No one can answer this except for you, as each client has its own pros and cons associated with its use. Just like any of the previous generations, you and only you will have to try out the different peer to peer file sharing clients and networks till you find one that works for you. There are too many clients to list, since there are still many different networks to choose from and a plethora of different modified clients available for each network. Every time someone gets a client, but feels it may be missing some option, they then get the open source source code and make their own modifications to that source code then release it as a new extended version of the original program.

Ever wonder how do you find good Expired Domains? Network Solutions just invented an incredible tool. It is an RSS feed creator that you can use to generate a simple, easy to read feed with info on upcoming expiring domains. One way people get domains are from those registered and for whatever reason, the owner let’s the Domain Names expire. In fact, some people see worth in certain expiring Domain Names and try to quickly snatch them up as they expire. One of the most interesting things about domaining is that you can get lucky when you find a valuable domain name that has expired. For whatever reason, the current owner did not pay to keep it for another year. Network solutions has this new expired domains feed feature. How it works is you subscribe to the feed and you can get live updates of expired domains you may be interested. Just simply visit and enter your keywords, enter search criteria, and it can refer to automatically to tell you matching feeds? Try to created an expired domain name feed on the word “autopilot” and experience the creation process yourself. Well now you can simply sit back and watch for great Domain Names that roll in on the Network Solution RSS Feed and purchase them after they have expired. Alerts on the expiring domain names meeting your search criteria will be sent out via RSS feeds. http://www.networksolutions.com/domain-name-registration/expiring-domains-rss.jsp

There are two major forms of the 4th generation of peer to peer file sharing protocols, both of which conform to the ideals of live streams. Whether you are talking about the RSS syndication of broadcatching, or the broadcast of the iPod (podcasting), the general consensus is that your are talking about the 4th generation of peer to peer file sharing networks.

Broadcatching was first brought to realization by Fen Labalme back in 1983, when he described the term as being an aggregated feed of data. The aggregator could then automatically receive and filter this data based on a set of variables determined by the independent user from multiple sources. Again in 1987, the tem was used again in a book by Stewart Brand as a means to help describe the concept of artificial intelligence and its interaction with the world. But it would not be until 2003 when Steve Gillmor came up with the idea of combining the concepts of the bit torrent protocol with an RSS feed as a means to continuously subscribe to media files from a given source. After many years and theorization, it would not be until 2004 when Andrew Grumet would officially integrate an RSS feed with a bit torrent peer to peer file sharing client.

The other form of live streaming peer to peer file sharing protocols is that of the podcast. The podcast actually derives its name as a conjunction of the iPod and broadcast, but that does not mean that you have to own an iPod. The concept of podcasting is very similar to broadcathing but it does not require a bit torrent peer to peer file sharing client rather it can accept the RSS feed straight through a website. The major difference is that accessing a podcast through a website allows one to download the media and place it on virtually any type of portable media device.

Regardless of the forms that are available, the 4th generation of peer to peer file sharing networks is here and you may have used one without even knowing it. For example, if you have ever used You Tube, then you have used one of the more basic forms of this generation of file sharing networks. Although you cannot actually download the file unless you have a download helper like one of the many add-ons available for Mozilla FireFox. But the entire You Tube network is available via an RSS feed right to practically any place you want it and that includes right to your desktop if you wish it to be so.

The point is that the peer to peer file sharing networks, regardless of which generation you prefer, are here to stay. As long as there is software and media files being made for the general public, and as long as the costs are too high, the file sharing networks will not be going anywhere other than up. As each new technology is created to prevent these programs from working, another technology is created just to counter it. It is a never ending battle between the copyrighters and those who believe that data should be shared freely amongst the others of the world.

The idea of peercasting plays an important role in the 4th generation of peer to peer file sharing networks, as it allows for a node to broadcast multiple live streams of data at the same time. The reason peercasting has been introduced into the 4th generation of peer to peer networks is for the simple fact that many downloaders wish to be able to preview a file as it is being downloaded. Due to the nature of peercasting, since it is basically a live stream, one can preview as he/she is downloading the file regardless as to whether it is a video or music file.

There have been a number of issues associated with the development of peercasting, most of which has to do with the connections themselves. In order to counter these connection issues which has plagued the peercasting networks, the concept of substreaming was developed into the networks. In all basic form, what happens is that when one node is peercasting, their client is actually sending out multiple simultaneous broadcasts of the same file, but to different nodes, this way if a connection is lost or rerouted, the stream can still be found again allowing the user to pick up the download where it was left at when the connection changed.

One of the most common forms of streaming peer to peer file sharing networks is that of the CoolStreaming network which allows a user/node broadcast a television show, thus the term peer to peer TV or for simplicity P2PTV. There are currently over 1 million users of this P2PTV form of file sharing.

In general however, the concepts of the peer to peer network have stayed the same, only the actual protocols have changed. When speaking about the tree structure of the 4th generation of peer to peer file sharing network, one must look at the older generations for the answer. Quite simply, most of the 4th generation of peer to peer file sharing protocols follow the same basic tree structure as the bit torrent protocol due to the fact that this network has already proven time after time to be one of the most stable peer to peer network as of date. The use of multiple nodes in which some nodes are considered as more than equal make connections to newer nodes as they connect and search for one of these super nodes. It is these super nodes that will then route all incoming as well as outgoing connections for the client in order to ensure that the network will not bottle neck.
