What is peer-to-peer? Peer-to-peer (better known as P2P sharing) is an advanced networking system that is way different from the client-server model. What is the client-server model? Well, any damn website is the best example of a client-server model. We, as visitors, are the clients who request the server to show the webpage. So it basically is a one-to-one correspondence. The client requests a page and the server obliges. The same logic applies for sharing a file. If you want to download a software, say ‘Google talk’, you go to the Google page and download it. If your friend wants it too, he too goes to the same site. Thus the same server doles out downloads to whoever requests it. A server is basically a computer that is online 24hrs a day, 7 days a week. Suppose I create a software and I want to share with friends. The software I create will be on my PC. So do I have to keep it connected to the net all day? My telephone bills would definitely set new records month after month!! Fear not, here’s where P2P comes in handy. It works differently from the client server model. It works on the basic principle that when someone other than me downloads the entire software, he too becomes a server. So if a third person wants to download it too, he downloads parts of it from both us. Then, he too becomes a server thus, as many people it reduces precious bandwidth consumption for each of the peers involved. Thus the file can be easily shared ‘Peer-to-Peer’. While the concept seems all rosy, the history of P2P sharing hasn’t been so. It has lead to various piracy issues in the past. I mean who’s stopping me from sharing a copyrighted file? Piracy protectors have a hard time with P2P. But then comes the big question: To Peer or not To Peer??While P2P can be a boon for budding software developers (people like us, maybe), it can be a pain in the ‘you know what’ for creators of authentic material like the entertainment industry, software companies etc. So it all boils down to one’s own discretion. Advantages:You could find whatever you want whenever you want. Afterall if you need a particular file, someone in the World Wide Web must have it! You’ll never miss out on that sound track you heard in the rickshaw today, any movie, documentary, project… whatever, whenever! Disadvantages:You need a P2P software for it. Not a big problem though. The popular ones are: LimeWire (www.limewire.com) BearShare (www.bearshare.com) EMule (http://sourceforge.net/projects/emule/) Shereaza (www.shareaza.com) to name a few. So is the P2P concept still a budding concept. Definitely not! It’s been there since as early as the 1970s! But then it hasn’t gained momentum in our part of the world. A little awareness would do us good. So P2P anyone?

As I'm a big music fan I would add Soulseek (http://www.slsknet.org/) to that list and some bittorrent client also. For the rest of the article is good enough for me.

personally i would also add a small section about security as it is a mjor consideration these days and p2p clients arent exactly the best way to keep your machine secured! otherwise its good and informative!

Also as a disadvantage that law isn't generally clear on p2p. It depends on countries but anyway, you have to be cautious if you use them sometimes. And maybe you could mention which p2p contain spyware, related to the security section that shadowx has just suggested.

You didn't mention that peer-to-peer is important in the gaming field, and how it could potentially perform better than the client-server model. Although it seems like that's not what your work is concerned about, you can't skip such an important part of it.

That's a good article, very simple and concise. I love P2P, the software including it is probably my favorite type of Software . Although, a lot of P2P software does have its downfalls (Filled with trojans, viruses, and spy ware), I think Peer-to-Peer needs to stay and continue to grow, and now with the newer malicious free programs this is rarely an issue (especially when compared to the original Kazaa). I love P2P!

P2P is illegal here in america, but there is always some people who still do it and there is some more programs I read on limewire and it uses java, i think I read and thats really bad because that takes alot of space and slows down your computer's browser. It would be really bad if you have dail up but theres others that don't require it like ares, I don't use P2P because I say its better to buy something like a song or movie and be safe instead of getting caught and getting fined with 250,000 dollars and plus some time in prison.

P2P is important for the upcoming gaming industry, like Supreme Commander for example uses p2p for online play, p2p will always have its downsides yes, but if you don't go around downloading illegal programs then it isn't that bad, a little searching around for some faqs, some game servers etc. p2p cannot be destroyed someday people will learn the message bill gates has been trying to spread and everybody would start to use p2p for legitimate stuff

P2P is not illegal. Sharing copyrighted material is illegal. You can own limewire, bearshare, emule utorrent ect on your computer legally. You can;t download copyrighted material however. Some people who do it? Millions of users use it... HTTP traffic (that would be web surfing) accounts for %46 of traffic while P2P accounts for %36 of traffic. Those numbers show more than "some" users use it. QUOTE "Presently, as a result of streaming audio and video in Web downloads, HTTP is approximately 46% of all traffic on the network. P2P continues as a strong second place at 37% of total traffic. Newsgroups (9%), non-HTTP video streaming (3%), gaming (2%) and VoIP (1%) are the next widely used applications." http://www.dslreports.com/shownews/85022Further more... they have reports that show even higher numbers in P2P useage, up to 80% in some areas and the above article may be incorrect. QUOTE "We find the actual P2P numbers to be much higher (at least 50-60% of total traffic) in most regions and ISPs and in some cases to stand at 80% (even today)," Eitan Efron of Oversi tells the website. http://www.dslreports.com/shownews/HTTP-Is...After-All-85138

This was a well written article with a lot of good information. While I usually am a fan of peer-to-peer networks....i'm also starting to see a change in the trends. We learned a lot about web 2.0 in one of my classes for college. Basically the whole idea of web 2.0 is sharing and collaboration. In a simple way - peer production. Using resources that we all have and working together for a common goal. Facebook, Myspace, Youtube.......they all require peer-to-peer production. People make those sites and without the work they put in we wouldn't have them. Think about the new Facebook applications. Anyone can make any type of application and have it used worldwide. It's a way for the overall product to get better while using all the available resources. The comparisons we got in class for peer production and collaboration were about Goldcorp Drilling and Linux. With Goldcorp.....this fledgling drilling company.....they needed a new way to find the stuff they were looking for (oil i believe). So what the CEO of Goldcorp did was completely reveal all the information they have. All the drilling locations they've been to.....what they're looking for......etc. IT was really a mind-blowing concept in the business world where a company's secrets are usually held close to their hearts and not released to people. But Goldcorp released the info, and asked for help. They said "Give us your ideas" and people responded. A ton of people had great ideas and different ways to figure this stuff out that Goldcorp had never thought of. They went from 100 million dollar company to a 9 billion dollar juggernaut. Linux is the same thing. In case you don't know what it is.........it's an Operating System that was built and is maintained on the idea of collaboration. It's open source so you can change stuff to make it better......but only if you share your ideas with everyone else. It's amazing and peer-to-peer really is the wave of the future. Get on or get lost.........it's going to be big.

Thanks for this useful article! I never knew (and never bothered to find out) exactly how P2P works. I only use it lol One of the few annoying things about p2p is that sometimes you end up never being able to download the whole file you want especially if it's a huge file, and it's far slower than downloading from regular file hosts.

Nice article you wrote, i'd make a defined statement that theres a difference of P2P (Pay 2 Play) and what your talking about. Theres a huge difference just about, and can sometimes be mistaken when your talking (depending on the context). Obviously you know what your talking about, and thought it out, good job  . Hope to read more articles like this by you.

Hey I didn't know P2P is being used by games for multiplayer gaming! That comes as news to me!!! I'll do some research on that and put it in the article too. Thanks a lot guys! But whoever thought of the idea of P2P must be a genius though many people use it for wrong purposes.True it is always best to buy copyrighted music but P2P can be helpful if you want to distribute something like a customised version of some linux distro!!!! In that case you won't find a better solution than P2P.
