The Federal Trade Commission and Distributed Computing Industry Association locked horns over a proposed law that would govern peer-to-peer networking technology would be used and regulated. Read more

Fear and Loathing in Windows 7: Testing Branch Cache using Linux

tyson.kopczynski — Thu, 09 Apr 2009 11:38:42 +0000

Unless you have been in a closet for the past couple of months, one of the new features in Windows 7 is called Branch Cache. For some time now, I've been meaning to test this feature, and over the past couple of weeks I managed to squeeze in time to take a closer look. First off, for those not familiar with what Branch Cache does here is how Microsoft defines it: Read more

Peer-to-peer networks get another black eye with child porn bust

Layer 8 — Thu, 21 Aug 2008 19:08:33 +0000

Federal investigators targeting the use of peer-to-peer networks for nefarious deeds have charged 52 people with using those networks to exchange graphic images and videos of children. The charges are the result of a coordinated law enforcement investigation that used sophisticated computer programs to track down computers on which child pornography was being stored and made available to others via...

Cloud computing vs. P2P

NetworkWorld Community — Fri, 15 Aug 2008 13:48:04 +0000

Are centralized "clouds" just too risky for your data? Some companies are looking to build similar functionality, but through distributed networks. Read/Write Web lists some P2P startups.

Instead of blocking, they just disconnect now

Thu, 07 Aug 2008 13:18:34 +0000

It would appear to me that Comcast is taking a new tactic. I am a game mod developer and one of the ways I release updates to my games is through bittorrent since the files are usually small and are not illegal for someone to download. Lately I have noticed when I turn on my bittorrent software within minutes I lose my internet connection through Comcast. I turn off the software, reset my router and everything works fine. I then turn the software back on and once again I lose the connection. I can go hours with no problems, but the second I try to release the torrent I am booted. I find it difficult to believe this is coincidence.

P2P management without data privacy issues

Gary_MacIsaac — Fri, 20 Jun 2008 03:21:34 +0000

Some of the most common P2P protocols result in unusual and problematic patterns of network behaviour because the overlay networks they create are at odds with the normal behaviour of Internet traffic. Using a unique, patented approach to monitoring certain statistical properties of each client's network activity--without examining packet headers or content--allows us to accurately detect and measure the intensity of individual user P2P upload activity with no impact on network throughput or end-user privacy. This approach has been successfully used simultaneously and in real-time on hundreds of wired Ethernet links operating at speeds up to 1 Gbps with no ill effect on network performance. http://www.orcaflow.ca

Yale researchers pitch a better way to do P2P: P4P

Alpha Doggs — Wed, 28 May 2008 18:21:27 +0000

Yale researchers are leading the way on a system designed to enable ISPs to better handle the crush of peer-to-peer (P2P) traffic increasingly gobbling up network bandwidth. Their P4P scheme will be the subject of a paper to be presented this summer at ACM SIGCOMM 2008 in Seattle. Read more

Can't this be built without the servers?

dan_linder — Tue, 18 Mar 2008 21:09:44 +0000

Why not take a normal bittorrent client and have it determine the number of hops between it and the remote systems, then preference taking the nearest ones? I understand that there are some things that the client would have a very hard time determining (congestion, dis-joint networks that appear local, etc) but this too should give quite a lot to both the consumer and their ISP. The consumer would get faster downloads (assuming people within their same MAN were also seeding the same files), and the ISP would get a lesser ding to their carrier trunk.

FCC investigates Comcast traffic interference claims

videonet — Wed, 27 Feb 2008 21:36:17 +0000

Hundreds gathered at Harvard’s law school on Thursday for an FCC hearing on net neutrality. At issue is whether all traffic on the internet should be treated equally. The FCC is investigating complaints that Comcast has interfered with certain types of web traffic, specifically peer to peer file-sharing. Read more

RE: Comcast's defense of P2P traffic management practices meets skepticism

Wed, 20 Feb 2008 14:12:45 +0000

I'll be putting a sniffer on the port tonight and start looking for them! If I see them (I don't use P2P apps), they will be hearing from me. Net neutrality, net neutrality....

Comcast blocking some P-to-P traffic

Paul McNamara — Fri, 19 Oct 2007 13:58:48 +0000

Comcast can expect a lot more customers to come calling armed with hammers after fans of file-sharing get a gander at this Associated Press report that describes how the service provider is indiscriminately blocking peer-to-peer traffic.And 'Net neutrality advocates will have a heavy new cudgel at their disposal, too, with which they are certain to pound the desks of lawmakers and regulators.

Anybody have a legitimate use for P2P in an office environment?

Mon, 30 Jul 2007 14:04:50 +0000

What company needs to allow programs like Limewire, Kazaa, ShareBear, or any of the other P2P programs? Why not just block all P2P traffic and let people infect their systems at home if they want illegal music or file downloads? Anybody have a legitimate use for P2P in an office environment? Re: IM attacks up nearly 80%, Akonix says. Anybody?

RE: Classified U.S. military info available over P2P

Fri, 27 Jul 2007 14:14:57 +0000

As a CISSP I am not a bit surprised. These are all the result of untrained or inadequately trained users. Re: Classified U.S. military info available over P2P. The fact that classified information is on computer systems with unencrypted access to the internet is a breakdown in security procedures. The CISO's for the network have some resposibility however, for failing to have software that checks the security of systems accessing their networks.
