P2P

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.

FCC's Comcast Ruling Inconsistent and Incoherent

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»

Another Wrong-Headed WSJ Editorial

Those wacky editorial writers at the Wall Street Journal just cannot seem to get the facts straight about network neutrality and what the FCC has done or can do on this matter. In the July 30, 2008 edition (Review and Outlook A14), the Journal vilifies FCC Chairman Kevin Martin for starting along the slippery slope of regulating Internet content. The Journal writers just seem to love hyperbole, and are not beyond ignoring the facts when they do not support a party line. Here are a few examples from the editorial... more»

FCC and Comcast: Reasonably Vague

So, the FCC will recommend that Comcast be "punished" or receive "sanctions" for its peer-to-peer throttling practice. And the network neutrality debate goes on, as does its ambiguities and vagueness. Even if you hate Comcast and agree with the net neutrality argument and the FCC's decision, one thing Comcast is correct in saying is that "reasonable network management" specified by the FCC in network neutrality policy set in 2005 is vague. Actually, the term "network management" by itself is broad before you even try to interpret what is meant by "reasonable", and it is not exactly correct in its application here... more»

No Fines for Comcast

Note: this is an update on my earlier story, which incorrectly said that the AP reported that Chairman Martin was seeking to impose "fines" on Comcast. In fact, the story used the word "punish" rather than "fine," and a headline writer at the New York Times added "penalty" to it "F.C.C. Chairman Favors Penalty on Comcast" (I won't quote the story because I'm a blogger and the AP is the AP, so click through.) Much of the initial reaction to the story was obviously colored by the headline. more»

Cisco: P2P Flat in North America? Some Experiencing Major Growth

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»

Introductory Remarks from Innovation '08

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»

SIP Revolution, Massively Delayed - But There's Hope

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»

Revision3 and Media Defender

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 descriptionmore»

The End of End-to-End?

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»

FCC's Stanford Hearing on Broadband Practices

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»
