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.

Interesting things happening in China. An article in the English edition of the People's Daily on line is headlined, Decimal network security address begins operation: "China's decimal network security address was officially launched. China has made a fundamental breakthrough in its Internet development; and actual use has been successful. The birth of decimal network technology makes China the only country able to unify domain names, IP addresses and MAC addresses into the text of a metric system..." Someone asked whether this was a rumored IPv9? It appears IPv9 is a project name, not a new protocol. It lumps together several activities, including at least... more»
This is big... For the upper band C Block, the FCC mandated that any winning licensee have in place "no locking" and "no blocking" provisions conditioning its use of this spectrum: "Licensees offering service on spectrum subject to this section shall not deny, limit, or restrict the ability of their customers to use the devices and applications of their choice on the licensee..." The no-locking, no-blocking requirements were hedged in by substantial limitations... But it's still important... Particularly if Google is the winning bidder, something we may not know for a month or so. 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»
Internet Service Providers (ISPs) have to do a lot more than just provide a pipe from your residence to their facilities to assure that you have a good Internet experience. There is a raging debate, inextricable from the debate on Network Neutrality, both on what the proper responsibilities of an ISP are AND what methods are proper for carrying out those responsibilities. Recently Comcast has received a serious black eye for blocking BitTorrent traffic in what it says was just a legitimate exercise in protecting most users from the few who abuse their "unlimited access"... Even if we give Comcast the benefit of the doubt and assume they are not influenced at all in their decision of what traffic to block by the fact that P2P protocols like BitTorrent are used to distribute material which competes for precious user attention with the content that Comcast sells, what Comcast is doing is still wrong if not illegal. more»
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»
In a non-operational NANOG discussion about Google bandwidth uses, several statements were made. It all started from the following post by Mark Boolootian: "Cringley has a theory and it involves Google, video, and oversubscribed backbones..." The following comment has to be one of the most important comments in the entire article and its a bit disturbing... more»
Spam on P2P networks used to be mainly with advertising inside downloaded movies and pictures (mainly pornographic in nature), as well as by hiding viruses and other malware in downloaded warez and most any other file type (from zip archives to movie files). Further, P2P networks were in the past used for harvesting by spammers. Today, P2P has become a direct to customer spamvertizing medium. This has been an ongoing change for a while. As we speak, it is moving from a proof of concept trial to a full spread of spam, day in, day out... more»
From the perspective of Internet security operations, here is what Net Neutrality means to me. I am not saying these issues aren't important, I am saying they are basically arguing over the colour of bits and self-marginalizing themselves. For a while now I tried not to comment on the Net Neutrality non-issue, much like I didn't comment much on the whole "owning the Internet by owning the Domain Name System" thingie. Here it goes anyway. Two years ago I strongly advocated that consumer ISP's should block some ports, either as incident response measures or as permanent security measures... more»
Black Frog -- a new effort to continue the SO-CALLED Blue Security fight against spammers. A botnet, a crime, a stupid idea that I wish would have worked -- News items on Black Frog. Blue Frog by Blue Security was a good effort. Why? Because they wanted to "get spammers back". They withstood tremendous DDoS attacks and abuse reports, getting kicked from ISP after ISP. ...The road to hell is filled with good intentions. Theirs was golden, but they got to hell, quite literally, non-the-less. ...When Blue Security went down, some of us made a bet as to when two bored guys sitting and planning their millions in some café would show up, with Blue Security's business plan minus the DDoS factor. Well -- they just did. more»
The growing popularity of smartphones, IPTV and other gadgets connecting to the Internet is eating up real estate on the net, and soon techies can expect cyberspace to run out of room, according to a Frost & Sullivan analyst briefing Thursday.
Experts say today's Internet protocol version 4 (IPv4) also limits services of multimedia content and data communication, including mobile IP, P2P and video calls. With new mobile IPv6, telecommunication providers can easily roll out custom services from movies to ring tones to television. more»
I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more»
Is it just a coincidence that some of the leading Internet-based application companies are pushing aggressively into network connectivity at exactly the same time the major telephone companies are pushing into content? Or are we witnessing the end of the Internet as we know it? Think back to the online world fifteen years ago. There was AOL, there was Compuserve, there was Prodigy, and there was Apple's eWorld. Sure, there were researchers and students posting to Usenet newsgroups and navigating through Gopher sites, but the Internet was a sideshow for individuals and business users. ...the online world of those days was fragmented and small. Every online service was an island. Are we going back to those days? more»
The Domain Name System is often though of as an integral part of the Internet. Without it, how can you ever locate anything? Well, quite easily, thank you very much. DNS is used implicitly for many services, such as web browsing. It also includes explicit extensions for a few applications such as e-mail. (I'm talking here about DNS the system, not DNS the technology that can be re-purposed to things like ENUM.) But the most notable thing about DNS is its receding importance... more»
A recent study conducted by Blue Security reports how Internet users can unknowingly expose their contacts' emails addresses to Spammers while sharing files, music, games and DVDs over Peer-to-Peer (P2P) networks. The study has uncovered hundreds of incidents where files containing email addresses were made accessible in P2P networks. more»
This morning, at 10 am in 2141 Rayburn, the Subcommittee on Courts, the Internet, and Intellectual Property is holding a hearing on "Internet Domain Name Fraud -- New Criminal and Civil Enforcement Tools." At that hearing, the Subcommittee will be considering a new Whois bill creating new penalties for people who provide false data when registering a domain name. We need to raise our collective eyebrows at this bill (which was suddenly dropped the evening before this hearing). The title of the bill is the "Fraudulent Online Identity Sanctions Act."
