The YouTube effect: HTTP traffic now eclipses P2P
« on: 19. June 2007., 19:33:43 »
In the Internet traffic race, P2P used to be way out in front. For years, P2P traffic eclipsed HTTP traffic as broadband users slurped down music and movies, some of which were actually legal. But P2P fell behind this year; for the first time in four years, HTTP traffic is out in front.

Ellacoya Networks, makers of deep packet inspection gear for carriers, has pulled together some statistics on one million broadband users in North America, and its findings show that HTTP traffic accounts for 46 percent of all broadband traffic. P2P applications now account for only 37 percent.

Chalk it up to YouTube and other Internet video sharing sites. The surge in HTTP traffic is largely a surge in the use of streaming media, mostly video.

Breaking down the HTTP traffic, Ellacoya says that only 45 percent is used to pull down traditional web pages with text and images. The rest is mostly made up of streaming video (36 percent) and streaming audio (five percent). YouTube alone has grown so big that it now accounts for 20 percent of all HTTP traffic, or more than half of all HTTP streaming video.

Looking over all the numbers, one of the most surprising result is the continued success of NNTP (newsgroups) traffic, which still accounts for nine percent of the total. Clearly, newsgroup discussions (and, ahem, binaries) are still big business.

The data may provide some ammunition for companies that favor traffic shaping on their networks. Between P2P, newsgroups, and streaming HTTP video traffic, the vast majority of Internet traffic is non-critical (i.e., no one's going to die or lose $20 million if they don't download a YouTube clip or a new song in under a minute). Networks that want to ensure priority transmission of VoIP calls, traditional HTTP web browsing, medical imaging, etc., have a strong incentive to throttle back that flood of non-critical traffic when the network is experiencing heavy loads. That could bring them into conflict with proponents of strict network neutrality, though, who don't want to see any sort of packet prioritization.
