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.

North American p2p went from 370 petabytes in 2006 to only 416 petabytes in 2007 according to Cisco's figures. Since U.S. users increased 16% in the same period, that's a drop in p2p per user and a significant drop in p2p as a percentage of all traffic. There's a major margin of error in these figures, so I'm calling it "flat." That's very different from pre 2007 experience, when p2p grew rapidly. It severely contradicts what many in Washington D.C. are saying... more»
Here's my opening remarks from Media Access Project's Innovation '08 in Santa Clara this morning. A DVD will be available shortly. This was a lively discussion, with Google and Vuze on the case. Good morning and welcome. My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi... I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain. more»
The SIP Center asked for an article which I finally wrote the weekend before last. My article was actually rather negative, but they published it anyway. Now I'm feeling a little guilty as there is an optimistic note I could have used as my conclusion. So let me try again... First let me summarize my problem. When SIP emerged in 1996, it's support for direct connections from one user to another was extremely compelling. This was the VoIP protocol which would lead to a complete revolution in communications... more»
Lots of coverage in the last two days about a Memorial Day weekend attack that took down the servers of Revision3, an Internet video network. This story has a lot of ingredients -- P2P maneuvering, DDoS attack, copyright vs. piracy, talk of laws broken and the FBI investigating. What's the CircleID take? Revision3's description. more»
One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more»
About 300 people attended to the net neutrality hearing Thursday hearing which began with testimony from Larry Lessig, a Stanford Law School professor and founder of the Center for Internet and Society... The meeting was called by the FCC in reaction to the news that US net firm Comcast had been exposed as managing traffic by stopping some of its 13m customers uploading files to BitTorrent and other peer-to-peer networks. The FCC has started a formal investigation to see if Comcast merits a fine for its actions. 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»
The Wall Street Journal today reported that FCC Chairman Kevin Martin wants to reject a Petition for Declaratory Ruling filed by Skype that would establish a wireless Carterfone policy, i.e., that wireless carriers must allow subscribers to use any compatible handset to access any application, content or software. Chairman Martin has confidence that the marketplace solutions obviate any necessary FCC intervention. Such optimism must derive in part from the apparently newfound willingness of one major wireless carrier, Verizon, to support aspects of open access. Perhaps Chairman Martin has confidence in the marketplace based on the magnanimous offer of most wireless carriers to pro-rate their early termination penalties by $5 a month. But here's the rub... more»
When I first read this post about Predictable Network Solutions on the excellent Telco 2.0 blog, I thought it was an April Fool's Day hoax. Then I remembered that it's a UK site, and some Googling confirmed that it's a real company. So my question is, will this technology -- or something like it -- eventually make network neutrality a non-issue? Or will it be the means for network operators to implement the discrimination that everyone is worried about? more»
Lee Dryburgh initiated a great thread in the Emerging Communications public group entitled What would your perfect phone be? There are 14 messages there at this moment with a lot of good ideas, but my first thought was the term "phone" is too limiting. Indeed, some of the correspondents' ideas also go far beyond the idea of a telephone. Here's what I want and fully expect to see, eventually. more»
One look at the speaker roster for the Emerging Communications (eComm) Conference 2008 being held here March 12-14 and it's clear participants can expect an intense three days of idea sharing and policy discussion on the future of the communications industry. ›››
eComm™ is a brand new telecom event for those interested in radical innovation and seizing the next opportunity wave. Skype will open day one, Google day two and Ribbit day three. March 12 to 14, 2008. ›››
