My disagreement is that even though 99.8% of machines *don't* have multiple routers, you seem to be pedantically insisting that some sort of IGP is mandatory for *all* end hosts, even though only 0.2% or so will actually see any benefit at all.. Not. Though hosts should implement some IGPs, the default can be to just depend on default routers supplied from DHCP. A better default could be that IGP will be automatically invoked if DHCP does not supply a default router. If there are multiple IGPs are implemented, snooping IGPs' advertisement to know which is the locally available IGP may also be a good idea. My point w.r.t. multiple next hop routers is that RA supplied information is not good enough, which means DHCP is no worse than RA even if there are multiple next hop routers. Masataka Ohta
Re: Comcast DNSSEC
Very cool, but they haven't signed *all* of them. comcast.net still isn't signed, nor are any of the reverse zones, nor is comcastonline.com (in Comcast's SOAs). We'll be there very soon. Sometimes unplanned work in other areas pulls resources temporarily, conspiring against the best plans. ;-) - JL Still, I'm glad they're doing it, and hopefully reality will catch up with their announcement soon. :-) -- Scott Schmit

You need some link state to even find a DHCP server. So, the very idea that DHCP would tell you where your routers are is preposterous on its face. Besides, that's terrible system design. You should never design a system where some code paths aren't exercised regularly. If there are multiple IGPs are implemented, snooping IGPs' advertisement to know which is the locally available IGP may also be a good idea. My point w.r.t. multiple next hop routers is that RA supplied information is not good enough, which means DHCP is no worse than RA even if there are multiple next hop routers. I've not read the whole thread yet (I had read the start what seems to be weeks ago), but I'll pipe up here and point out that in my _original_ design, every host was running a link state IGP. Even without any router at all, you need link state to handle mobile nodes, hidden terminals, partitioned networks, satellite versus land-line unidirectional links, etc, etc, etc. Of course, all that was ripped out by the ignorant folks who came later. Thus, IPv6 is much worse at self-configuration, security, mobility, and *everything* than originally envisioned.

Monday Night Footbal -- on Google?
In this week's CES coverage on Marketplace, venture capitalist Mark Suster of GRP Partners opines that Google will bid on the broadcast rights to MNF within the next 5 years. http://www.marketplace.org/topics/tech/ces-2012/future-television-way-we-watch Is 'The Internet' ready to deliver live 1080p HD with very close to zero dropouts to 25-30 million viewers for 4 hours straight every week, yet? People don't mind buffering in cat videos, but I'm pretty sure they don't want Tim Tebow's last pass of the game interrupted by an hourglass for 5 seconds. Will CDN's help this? Multicast?

But the TV should only be receiving one stream at a time, unless there is pip. Each stream would probably be around 5mbps. If multicast is used it shouldn't take 150pbps, it should be much lower.

That could be one of the things that helps spur v6 adoption - multicast being somewhat less of an afterthought :) While v4 multicast works, and delivering video is one of the things it can do very well, some networks don't route v4 multicast or exchange v4 multicast prefixes, so its utility on a wide scale can be limited. jms

I think not, and for the reason I just posted as a comment on Marketplace's story: I call it the Compatible Color problem. Due to DMCA, SOPA, and other such corporate paranoia legislation purchased by the large media conglomerates, we may end up in a situation where you need one box to watch Netflix, another box to watch Google, and so on and so on, yada yada. Once Congress gets over thinking it's cute to be ignorant of how the internet works (series of tubes, right?), that probably won't play in Washington anymore than it plays in Peoria... but I hope it doesn't wait to *start* getting worked on until The Super Bowl is next Sunday! And my TV doesn't *do* Google!!! Cause that Would Be Bad. (These problems have, of course, Already Been Solved.

I believe you're an optimist. Weekly football is probably the second most important thing on a TV network behind the championships for whatever sport they're carrying, in a year. I'm not saying you need the whole 19mbps (though, remember here, we are not talking about Additional Carriage; we are talking about *being the only way people can see that game* -- and my example was the Super Bowl).. but unless MPEG algorithms have gotten *much* better than I'm aware of, 5mb/s is probably not enough for the Super Bowl. And you'd really be better off with some FEC, too, even if it costs you a couple frames extra delay. Cheers, -- jra -- Jay R.
