- Narwaffle, on 10/12/2007, -4/+30Short version of the video: Guy flies in through the window, starts shooting dudes. All of a sudden, ninjas jump through the *other* window and he's like "Oh noes!" and starts shooting laser beams. The ninjas are about to kill him when the pirates jump into the crossfire and have an all out freaking war. It's awesome.
/random - usherzx, on 10/12/2007, -1/+21it's about networking
- inspecality, on 10/12/2007, -3/+17Hour and a half? Someone please give a summary.
- t0ny, on 10/12/2007, -0/+9Interesting posted 18 mins ago and bad it to the front page, but the video is 1 and a half...
- Outdoor83, on 10/12/2007, -1/+9For anyone interested in networking, this is a must-see. It's well-done, very eloquent, and extremely informative.
- CeeJayDK, on 10/12/2007, -0/+8I've watched the whole thing , here's my summary :
Van Jacobson explains how changing the way you look at networking can make at lot of things much easier and talks about previous ways of looking at networking and then proposes a new way to look at networking.
Generation 1 : the phone system - focused on the wires that move data
Generation 2 : the Internet - changed focus to the endpoints (computer to computer , device to device)
Generation 3 : dissemination - Van suggests focusing instead on the data.
As I understand it , routers and switches in the future will forward packets based on their data and not the endpoints.
They will also cache the packets and when someone requests the same data they will send the data to the requesting routers or endpoints if they still hold a copy and they will multicast if they are on the same subnet.
The underlining idea being that the data can come from any device on the net , because the network no longer cares where the data comes from as long as it's the same data.
It should make multipoint to multipoint dissemination of data far more effective than it is today.
Very very cool stuff. - inactive, on 10/12/2007, -1/+6I don't really want to make a TCP connection to Google Video, all I want is to get a copy of the said video clip.
- Artemis11, on 10/12/2007, -4/+9Heh, Kevin Rose dugg it ;)
- pete6677, on 10/12/2007, -1/+5Doesn't that sort of defeat the purpose of the internet? Distance isn't supposed to matter.
- kflasch, on 10/12/2007, -0/+4Well, I think people digg things if they are *potentially* interesting even if they don't know if it is or if they like it, etc.
- Huitz, on 10/12/2007, -0/+4This is a really interesting lecture. However, I am not sure A) everyone is interested in fairly detailed networking research and B) Everyone will have the expertise to understand all of what he is saying (Though this is much more understandable than most of the related literature).
- geminitojanus, on 10/12/2007, -0/+3Interesting to the other 30%?
- Books, on 10/12/2007, -0/+3I'm studying telecommunications and this was an assignment of ours. Watch Van Jacobson's presentation and write about how the internet should be and such.
- geminitojanus, on 10/12/2007, -0/+3You must have had your ears on something else when you were listening to this lecture; he brings up a lot of interesting ideas about data-based routing, building new "last mile" lines, and wide area content caching/storage networks. IPv6 only starts to solve some of the location-based problems (multicast, more-permanent address assignments), the protocol level above it (TCP) will need to address the rest. It's a very interesting talk.
- Plinkyle, on 10/12/2007, -1/+4I'd like to hear him talk more about the problem of net connectivity being binary (you're connected or you're not, there's no in between). Perhaps using his model of next-gen connectivity you could be partially connected in that you could access information stored in nodes near you, but not necessarily throughout the entire net? But he also talks about the net being a connected graph, so it seems like connectivity almost has to be binary. Anyway, just some thoughts.
- catfive, on 10/12/2007, -0/+2If you're on the fence about watching, know this: he also rips on Fox News, Republicans, Intelligent Design, and the RIAA (seriously).
Now watch the diggs shoot up. - Redemption289, on 10/12/2007, -1/+3yes, thats not the way current graph theory works. If you can see a vertex, and that vertex has edges leading to other vertices, you can see those vertices as well (it may just be slower).
Also, of course distance matters. Thats why it takes much longer to download something that isn't directly connected to you. You have to traverse a lot of edges to get that information. - MOGua, on 10/12/2007, -0/+2The hard part is to convince the ISPs and network owners to actually use these new ideas that are being actively researched in the forefront of networking.
Most of the Cisco routers that everybody's using have all the multicast features ready but they just don't want to turn them on...In fact nobody wants to turn any of these new features on.
If you can't bill your customers easily, nobody will use it. It's really all about the money for these greedy corps. - Flashman, on 10/12/2007, -2/+4Thanks Narwaffle, now I'll definitely watch it!
- uidzero, on 10/12/2007, -0/+2"Van Jacobson is a Research Fellow at PARC. Prior to that he was Chief Scientist and co-founder of ... all ยป Packet Design. Prior to that he was Chief Scientist at Cisco. Prior to that he was head of the Network Research group at Lawrence Berkeley National Laboratory."
It would have been easier to just say "Van Jacobson is most likely smarter then anyone watchnig this video" :-) - timbro1, on 10/12/2007, -0/+2Well im not 100% sure but what he is referring to in the video is putting certain techniques that are being implemented in the "aplication layer" into the actual networking protocol.
- 0seth0, on 10/12/2007, -0/+2Van Jacobson is a huge reason the internet, as we know it, exists! This was a good 'digg'. I especially found it interesting that he thinks we need a new "internet protocol" for the future. To me it makes sense, but i wouldn't think that i would hear from a major pioneer of the "old internet". If you can't at least appreciate this post then you shouldn't use the internet.
-seth - englishpaulm, on 10/12/2007, -1/+3An hour and a half? I thought digg users were severely ADD. Surprised if anyone actually watches this. I look forward to many postings with wildly different descriptions of what this video is actually about.
I know that I watched it in its entirety, and found the part about the dog who drives a golf cart to be hilarious! - geminitojanus, on 10/12/2007, -0/+2"all the data is just stored on the network randomly."
That's one of the biggest problems with Freenet (other than performance, but related); data needs to be spread out either evenly, or in such a way that it understands its locale and is persistent. A good example of this is at the very end of the talk when he speaks about bittorrent and one of the biggest problems with it being "torrent decay" with no persistence or explicit locale (for example, without a reverse-lookup on the IP address, you can't know where a particular computer is on the internet, and thusly bittorrent can't take location to mind when picking peers).
Take BitTorrent, move it to the protocol level, add geographic-based routing, add multicast, and you've got something that's a very close approximation of what this guy is talking about. [not to say that I particularly agree, but it is definitely interesting to say the least]. - bariswheel, on 10/12/2007, -1/+2typical Google Tech talks; second to none + highest standards.
- Miniman, on 10/12/2007, -2/+3VERY intresting. (least for 70% of diggers.)
- AlanLivingston, on 10/12/2007, -0/+1Wasn't there a Doctorow story like this? Where cars could network off of each other, playing music, I think.
I could envision where you might be able to have a large temporarily connected network along the highway with connectivity to the Internet on a limited basis as a car in your network segment came near an access point of some sort. Maybe if the network segment is large enough, there's always a path to the Internet because there's always a car or two near an access point. Kind of like cell towers. - Flashman, on 10/12/2007, -3/+4It's called social *bookmarking* for a reason.
- Xepo, on 10/12/2007, -0/+1Hmm, I've not completed the video yet, but this seems to be exactly the same thing as freenet. (http://freenetproject.org/). You access everything based on the checksum, there's no central server, all the data is just stored on the network randomly.
- Burgerman851, on 10/12/2007, -1/+2Never heard that one before. Thanks alot.
- ebunton, on 10/12/2007, -0/+1A brilliant insight into the future of networks. I thoroughly enjoyed every minute of the presentation.
Highly abstract thinker. I love the explanations of network architecture. - psyjoniz, on 10/12/2007, -0/+1Superbly informative. He takes you all the way through probably the most comprehensive explanation of the evolution of networking I have ever heard. And boiled down into that short of a time! Bravo. Then he speaks on his ideas. The entire thing is worth watching three times for anyone even remotely interested in the communication of our planet and where it might be headed. He wants to design and implement a network that solves a lot of issues with the current Internet and also goes a long way to prevent its possible disruption. I don't want to spoil it too much, but it really impressed me quite a lot.
- inspecality, on 10/12/2007, -0/+1Thanks CeeJayDK.
- hoelzro, on 10/12/2007, -1/+0I actually posted that at like 10:30 Sunday morning...it wasn't until about midnight that it became popular.
- uidzero, on 10/12/2007, -2/+1Yeah, I was hoping to find a copy of this video in a standard file format myself.
- macrymble, on 10/12/2007, -4/+1someone should count the number of times he says "ubiquitous", "amortize", and "agnostic"
- KyleGoetz, on 10/12/2007, -7/+2I'm surprised. How did this become gefrontpaged with only 25 diggs?
- ScottoGato, on 10/12/2007, -7/+1Your mom.
- Dakusan, on 10/12/2007, -8/+2Everything he talks about is already pretty much solved by IPv6 (broadcasting, encryption, tunneling, confirmation of packet order and data integrity, etc), pretty big waste of a watch/listen imo.
- FeartheKnighted, on 10/12/2007, -8/+1My time, valuable she is. Spark notes I need.
- Derrekito, on 10/12/2007, -9/+2I don't quite understand what your going on about. What do you mean by being partially connected?
- FeartheKnighted, on 10/12/2007, -7/+0^
Thank you, I do not. - doubleblack, on 10/12/2007, -9/+2He didn't invent the Internet, Al Gore did!
- CelebVoy, on 10/12/2007, -12/+1When I read "networking" I thought we were talking about the same thing that it means on myspace...now I am kind of disappointed.
