The New Internet Architecture (2) Van jacobson
June 1st, 2010 by Gordon Cook
A 2007 Van Jacobson talk is here
Then there is this very interesting entry can be found with a search for “Van Jacobson Google architecture”.
[Van Jacobson content-centric networking insights at the 4Ward … - 3:04pm Aug 18, 2009 … Van Jacobson content-centric networking insights at the 4Ward … In the large and content-dense talk (around 2,5 hs), Van provided many details of the CCN architecture]
I have read fairly carefully the 96 slide lecture of August 18, 2009 and find it extremely fascinating. What Bill is doing in his talk is describing how content and applications have moved to the edge over the past five years. And what Van seems to be saying is how to construct an overlay for the delivery of content that can run quite smoothly on TCP/IP yet be quite independent of the limitations such as IP before address space shortage that seem to be popping up all around us.
I wish I could say that I understand in any appreciable level of detail precisely what Van is doing — I do not. But I think I do see the general implications. With virtually unlimited storage and memory at our desktops and at the intelligent nodes at the edges of network the Akamaisation of the Internet becomes almost a foregone conclusion. Indeed it seems to me that Google to deliver its material has to be using Van Jacobson-like content centric networking protocols.
Now imagine running into this story on the front page of the New York Times website a couple of hours ago where it explains how an increasing number of geeks have downloaded the unreleased source code for Google’s Chrome operating system, put it on their lap tops or notebooks, added their own enhancements, and are happily using it as an OS to access the Internet.
What I find really intriguing is that very few people seem to comprehend the change since the popping of the Internet bubble in basic Internet architecture where you no longer assume that information is at some specific geographical location and depend on the network to follow the Old 1990 rules of going to that point in getting the information and bringing it across one or more backbones and through one or more Internet exchange points before it delivers it to you.
But the content providers, be they publishers in the old style or websites in the new style, have brought the information to the general vicinity of virtually every MSO head end or telco central office and it is only the duopoly’s last mile that stands in the way of an extraordinarily cost-effective access to the data. And it is Google of course that far more than anyone else has created an environment that invites everyone to live in Google’s Cloud. Net books and the Chrome OS would seem to be the final wrapping on the package. Of course the only inconvenience is the duopoly standing in the way of the average person’s access to the Cloud under such circumstances….. one must imagine,or at least hope, that it will become increasingly possible to jump over the moat.
What intrigues me is how long it will take before more people understand the change in architecture. And of course perhaps it’s the strategic significance of this change that leads everyone involved to be so proprietary about their service and the geographic locations on the surface. The people without any clothing look to me like the telco and MSO incumbents. They have warned us that they have no incentive to invest in their networks but at the same time, because they have fortified their stranglehold over the end-user, the rest of the world has had to build out to the very edges where the duopolists attach their customers. What kind of investment in what networks one must ask?
And because they have relied on their respective monopolies and, as Bill St. Arnaud points out, they have not done the kind of building out that the content and application providers have, they stand there potentially quite naked relying on secrecy, nondisclosure, obfuscation, lobbying and the whole nine yards to maintain the fiction that they control the kingdom when in reality what they control are only the drawbridges separating the people from the castle.
That is what I find so important about what Bill has written and for which you can get plenty of intellectual backup for from Van Jacobson’s content centric networking efforts. A Google control Internet running on Chrome and on a Van Jacobson-like content centric networking overlay of TCP/IP may not be everyone’s favorite Internet but it will be a force to be reckoned with. While it is tempting to think that the sooner the reckoning the better, one also must wonder how comfortable a Google controlled universe with no counter balance would be. A rather chilling spoof maybe viewed here. http://www.vidzshare.net/play.php?vid=16345
