A peer to peer (P2P) computer network uses diverse connectivity between participants in a network and the cumulative bandwidth of network participants rather than conventional centralized resources where a relatively low number of servers provide the core value to a service or application. P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes. Sharing content files containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.

Depending on whom you ask, peer-to-peer (P2P) services may be the best thing that ever happened to the Internet or a diabolical arbitrage scheme which will ruin all ISPs and bring an end to the Internet as we think we know it. Some famous P2P services include ICQ, Skype, Napster, and BitTorrent. Currently a new P2P service called iPlayer from BBC is causing some consternation and eliciting some threatening growls from British ISPs... more»
With my post earlier this month about the possibility of SIP botnets [also featured here on CircleID], I've had a number of people asking about more information and wondering about the possible impacts. And while I will write more on botnets in general, as far as the potential impact of "botnets" in general, one need only look over at the current situation in Estonia... Now, perhaps Russia is behind the attack... perhaps not. There are obviously much larger political issues going on between the two states. more»
Vonage's latest woes are written up by Om Malik in Vonage: How Low Can You Go. More interesting than Om's reportage (Sprint wins case, Vonage ordered to pay damages, stock drops to $1.30) is the commentary afterward, in which one reader takes Om to task for the "gleeful" way in which he reports the demise of the VoIP companies... Boosters made the argument that VoIP was fundamentally cheaper than the TDM systems that phone companies deploy, and so therefore they enjoyed a price advantage in the market place. Anyone in the business of supplying telecom equipment, however, will tell you that the argument is flawed... more»
Telecommunication companies need to go beyond just providing bandwidth and look into acquiring Internet destination sites that are heavily trafficked, Sun Chairman Scott McNealy said on Friday. "I have explained to every telco that either you become a destination site, or the destination site will become a telco," McNealy said at a news conference at Sun's Worldwide Education and Research Conference in San Francisco on Wednesday... more»
I ought to explain why I've suddenly gone cold on VoIP. It's just I've watched my own behaviour. I've grown tired of the inconsistency of PC VoIP calls, and instead I've reverted to using landlines, mobiles and Jajah (for callback). But I'm still using IM to set up many of those calls! The problem isn't unique to any one client - they're all proving unsuitable for business use with clients (which is most of my telephony needs covered). The worst of all seems to be Skype conference calling... more»
On the one hand, the big telcos are chanting the mantram, "We shall not block, impair or degrade any content, service or application." On the other hand, they're saying, "There's no problem. We don't need a law until there's a problem." Well, now. Mitch Shapiro over at IP & Democracy, points to Russell Shaw's post that says: "I have been noticing a growing number of posts in which many Vonage users and Vonage Forum Members have been complaining about the quality of Vonage calls over Comcast broadband connections..." more»
Skype's official explanation. Phil Wolff has a good set of interpolated comments on the official explanation. There are two things to add... As the Register points out, last Tuesday was Microsoft's monthly patch day and those patches required a re-boot. If we believe Skype that their problem started with excessive login attempts, this is the only plausible explanation on the table... more»
A fellow named Paul Korzeniowski has written a very good, concise piece on the Comcast action at the FCC for Forbes, Feds And Internet Service Providers Don't Mix. He manages to describe the controversy in clear and unemotional language, which contrasts sharply with the neutralists who constantly use emotionally-charged terms such as "blocking," "Deep Packet Inspection," "forgery," and "monopoly" to describe their discomfort. more»
Comcast has been in the news recently for deliberately "slowing down" some subscribers and applications in its broadband cable service. There was an article in the Washington Post today updating the case, and there was a recent article in Network World that actually favors the groups filing the complaints and calls for the FCC to crack down on Comcast. more»
Bell filed its response to the Canadian Association Of Internet Providers (CAIP) submission to the Canadian Radio-television and Telecommunications Commission (CRTC) on its throttling practices yesterday, unsurprisingly arguing that its actions are justified and that there is no need to deal with the issue on an emergency basis. Several points stand out from the submission including its non-response to the privacy concerns with deep-packet inspection... and its inference that P2P usage could be deemed using a connection as a "server" and therefore outside the boundaries of "fair and proportionate use" under typical ISP terms of use. more»
After more than four years during which peer-to-peer (P2P) applications have overwhelmingly consumed the largest percentage of bandwidth on the network, HTTP (Web) traffic has overtaken P2P and continues to grow says a report released by Ellacoya Networks. These findings are based on usage data of approximately one million broadband subscribers in North America. more»
After voting on the Comcast order today, Kevin Martin and his Democratic Party colleagues issued press releases telling us how they saved the Internet from Comcast's discriminatory practices, but they've failed to release the actual order they adopted and subsequently re-wrote. Commissioner McDowell wasn't allowed to see the revised order until 7:00 PM the night before the meeting. Rumor has it that high-level spin doctors are still trying to remove all the rough edges, inconsistencies, and factual errors. more»
Does "voice" communication really matter as much today in business communications? Think about it. When you need to reach someone today, what do you do? Do you call them on the phone? Or do you send them email? Or a text message? or IM? I know personally that my normal communication flow usually goes something like this: Instant Messaging; I check first to see if I can reach the person on some form of IM... SMS; if the matter is relatively important... E-mail/Facebook/Twitter/other; Previously that would have just been email, but these days I find myself very often sending messages via Facebook or Twitter... more»
Burton Group issued a press release last week announcing the conclusions of my recent report on Skype. I thought the release clearly stated our conclusions on Skype, which essentially were that there are indeed security and management concerns that enterprises ought to be aware of, but that those risks may be outweighed by the business benefits offered by the use of the application, and that enterprises must carefully weigh risk vs. reward when evaluating Skype usage. more»
Yesterday's post explained how peer-to-peer (P2P) applications use the processing power, bandwidth, and storage capacity of participants in a service rather than centralized resources. This makes such applications generally less subject to catastrophic failure, much less subject to running out of resources (since each new user brings new capacity as well as new demand), and much cheaper FOR THE PROVIDER of the application in terms of hardware and bandwidth required. It's the FOR THE PROVIDER part that's the rub. Let's consider the case of BBC's iPlayer service... more»
