[ NNSquad ] Re: The Once and Future King: Multicast looks to (finally) be the future of television.
I've long argued against multicast -- it's based on the assumption that we are broadcasting in the same way the phone network reveled in circuits.
If you need to fan out then you can do it at the edge with relays like Akamai.
What you don't want to do is pollute the network with a complex application protocol like multicast.
I can understand it's use local as a variation on ARP as long as you don't assume reliable delivery. But if you are delivering content than you need reliable delivery and it gets extremely complex.
This is very similar to the phone companies reveling in MPLS because they know deep in their lower bowels that the Internet is just like a telephone network.
Or maybe it’s a railroad (http://www.frankston.com/?name=VONRailroads). In fact it’s just like having railroad guys run an airline because they think they are in the transportation business when they are really in the rolling stock business.
But this is far worse – there is no business in transportation – just a business in laying down copper, glass and radios and getting out of the way as users do their own networking (http://www.frankston.com/?name=OurCFR, http://www.frankston.com/?name=SATNFSM)
What could be stupider than putting those most incapable of understanding the concept of user’s doing their own networking in the position of gatekeeper for our very ability to communicate and conduct business and look after our own safety.
You can’t make a profit for selling transport any more than you can make money operating a canal across the ocean and the carriers know this which is why I like to point to their own message in http://www.frankston.com/?name=AssuringScarcity.
The solution is not to fix the network nor V6 (http://www.frankston.com/?name=IPGeni2 and http://www.frankston.com/?name=InternetDynamic). It is to give us the ability to do our own networking rather than having to pay for a ride from the today’s robber barons.
But it’s 1934 and nothing can change because legislation doesn’t respond to reality – only to the meanest of intelligent designers.
‘nuf said – in the land of the blind the one-eyed many is considered insane. The blind rule.
this article from cringley may explain some isps behavior:
See, multicast IS a resource hog.
But to more and more ISPs multicast is looking like the best answer to a
huge bandwidth problem, while also being a sneaky way to take back control
of the Internet.
The first problem ISPs are facing is that they are running out of IP
addresses. Many, including Comcast (my ISP), are already reusing IP
addresses on subnets and are rapidly moving toward IPv6. The second
problem these ISPs are facing is they are running out of bandwidth at
layers 1 and 2 of the OSI protocol stack. We're not talking so much about
Internet bandwidth here but Intranet bandwidth -- bandwidth within the
ISP's own cable plant -- and this loss they blame primarily on P2P
In order to lower their bandwidth bills, ISPs are trying to take greater
control of the way we, their customers, use our "unlimited" bandwidth. So
Verizon and a lot of other DSL and wireless data providers are placing
download caps on their monthly service while Comcast has been traffic
shaping to limit the growth of P2P file-sharing services like BitTorrent.
This is all intended less to slap us around and more to keep ISP costs in
line so they can -- big secret coming -- CONTINUE TO MAKE NEARLY ALL THEIR
PROFIT FROM PROVIDING INTERNET SERVICE. You think your phone company makes
a lot of profit on voice and long distance or that your cable company
makes a lot on carrying video channels? Think again. Comcast barely breaks
even on video and makes a killing on Internet and VoIP. If cable company
Internet subscriptions fall, those companies are in real trouble.
Why, then, would they risk alienating us, their customers? Because they
think we are stupid, for one. And because they intend to offer us
alternatives, like IP Multicast.
Both Comcast and Verizon are rapidly rolling out IP multicast, as I am
sure most big cable and telephone ISPs are. Even Verizon's
fiber-to-the-home service, FiOS, is moving to multicast because it was
architected in a dumb way that sorely limits what should be a lot of
