Movie King of the Internet: Bad Idea

kong_iup2.jpg Andrew Odlyzko asks what if the duopoly gets its way and completely does away with net neutrality:
But what if they do get their wish, net neutrality is consigned to the dustbin, and they do build their new services, but nobody uses them? If the networks that are built are the ones that are publicly discussed, that is a likely prospect. What service providers publicly promise to do, if they are given complete control of their networks, is to build special facilities for streaming movies. But there are two fatal defects to that promise. One is that movies are unlikely to offer all that much revenue. The other is that delivering movies in real-time streaming mode is the wrong solution, expensive and unnecessary. If service providers are to derive significant revenues and profits by exploiting freedom from net neutrality limitations, they will need to engage in much more intrusive control of traffic than just provision of special channels for streaming movies.

The delusions of net neutrality, Andrew Odlyzko, School of Mathematics, University of Minnesota Minneapolis, MN 55455, USA odlyzko@umn.edu http://www.dtc.umn.edu/odlyzko Revised version, August 17, 2008

Why is that?
But video, and more generally content (defined as material prepared by professionals for wide distribution, such as movies, music, newscasts, and so on), is not king, and has never been king. While content has frequently dominated in terms of volume of traffic, connectivity has almost universally been valued much more highly and brought much higher revenues. Movies cannot be counted on to bring in anywhere near as much in revenues as voice services do today.
The Internet isn't about Sarnoff's Law (broadcast content like TV, radio, and newspapers) or even about Metcalfe's Law (1-n connectivity, like telephone or VoIP): it's about Reed's law, 2n-n connectivity, such as blogs, P2P, and facebook). That's my interpretation; Odlyzko probably wouldn't agree.

Anyway, that video content such as movies is king is one of the primary delusions Odlyzko addresses in this paper. The other is that movies need to be streamed in realtime. It is mysterious why people continue to believe that in the face of the massive evidence BitTorrent and other P2P services that deliver big content in chunks faster than realtime. I can only attribute this second delusion to a bellhead mindset that still thinks in terms of telephone, which was realtime because nobody knew any other way to do it back in the analog-copper-wire-connection day.

As Odlyzko sums it up:

The general conclusion is that the story presented by service providers, that they need to block net neutrality in order to be able to afford to construct special features in their networks for streaming movies, is simply not credible. If lack of net neutrality requirements is to be exploited, it will have to be done through other, much more intrusive means.
So why let the duopoly force a policy on everyone else that won't even work to the advantage of the duopoly?

One way to get net neutrality would be to let the duopoly have its way, and wait for it to implode. However, given that for streaming video to have any chance of succeeding, the duopoly would have to clamp down on everything else to eliminate any competition, I shudder to think what this would mean. The Internet as a source of real news and opinion would go away. Given that the vestigial traditional news media in the U.S. (TV, radio, newspapers) provide so little news, there's a very good chance that most people in the U.S. wouldn't even know how bad they had it as the country sped its slide into parochialism and irrelevance. How many people even know now that the U.S. has slid from #1 to #23 or whatever the latest number is in broadband uptake? If the duopoly is given its head, even fewer would know.

If we let King Kong Telco and T Rex Cableco battle it out to be Movie King of the Internet, where does that leave poor Fay Wray Public?

FCC, FTC, Congress, executive, and courts, not to mention the public, should all read Odlyzko's paper, and should all refuse the duopoly's demand for special privileges that won't even produce profits for the duopoly. Then all of above should legislate, enforce, and maintain net neutrality so we will all profit and benefit. Yes, even the duopoly can win with this.

Vigilantes Against BitTorrent? Revision3 Taken Down by SYN Floods

revision3_f5_dos.jpg Revision3 uses BitTorrent to distribute legal Internet television. It turns out using BitTorrent may be enough to subject a company to crippling online attack.
On the internet, computers say hi with a special type of packet, called “SYN”. A conversation between devices typically requires just one short SYN packet exchange, before moving on to larger messages containing real data. And most of the traffic cops on the internet – routers, firewalls and load balancers – are designed to mostly handle those larger messages. So a flood of SYN packets, just like a room full of hyperactive screaming toddlers, can cause all sorts of problems.

That’s what happened to us. Another device on the internet flooded one of our servers with an overdose of SYN packets, and it shut down – bringing the rest of Revision3 with it. In webspeak it’s called a Denial of Service attack – aka DoS – and it happens when one machine overwhelms another with too many packets, or messages, too quickly. The receiving machine attempts to deal with all that traffic, but in the end just gives up.

A bit of address translation, and we’d discovered our nemesis. But instead of some shadowy underground criminal syndicate, the packets were coming from right in our home state of California. In fact, we traced the vast majority of those packets to a public company called Artistdirect (ARTD.OB). Once we were able to get their internet provider on the line, they verified that yes, indeed, that internet address belonged to a subsidiary of Artist Direct, called MediaDefender.

The plot thickens from there. Well worth reading. I bet the legal proceedings will be even more interesting.
