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.

As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... 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»
At the Emerging Communications Conference eComm 2008, I'm moderating a panel "Wireless Innovation, with or without operators." This will be a discussion -- smart people from differing camps responding to (hopefully) probing questions from yours truly, and the audience. Points of view represented include Google Android, J2ME/JavaFX Mobile, iPhoneWebDev.com, Skype and Trolltech Qtopia (Nokia), plus Chris Sacca, formerly head of Google's wireless initiatives. I've been thinking about subjects and questions for the panel. As a start, I'll set down my current views, then seek others' views and questions. more»
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»
Time Warner Cable's planned experiment with tiered charging for Internet access has generated a flurry of coverage in the blogsphere, but no new insights (at least that I've seen). The primary problem ISP's complain about is that 5% of their customers use 90% of the available bandwidth and when they examine this traffic, it's mostly peer-to-peer file sharing... more»
Let's say that providing communications infrastructure is an inherent function of a state. Most people think of the internet as a telephone system, and most people think the telephone companies aren't supposed to choose which calls will go through based on their content. People think that because they think internet access, like telephone access, is a utility -- like electricity conduit, water pipes, etc. -- that has something to do with the government, and the government isn't supposed to discriminate. more»
Your wireless carrier (in the U.S., probably AT&T or Verizon Wireless) has a lot of control over the handset you can use and the applications that can run on that device. In fact, wireless carriers routinely ask for (and get) an enormous slice of the revenue from applications that work on their networks, and they force handset manufacturers to jump through all kinds of hoops in order to be allowed to sell devices that can connect to these networks... This has had bad effects on the ecosystem of the wireless world. 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»
The Storm worm has gotten a lot of press this year, with a lot of the coverage tending toward the apocalyptic. There's no question that it's one of the most successful pieces of malware to date, but just how successful is it? Last weekend, Brandon Enright of UC San Diego gave a informal talk at the Toorcon conference in which he reported on his analysis of the Storm botnet. According to his quite informative slides, Storm has evolved quite a lot over the past year... 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. ›››
