How many Youtube subject tags will fit in *your* routers' TCAM? http://tech.slashdot.org/story/14/09/04/2156232/ucla-cisco-more-launch-consortium-to-replace-tcpip [ Can someone convince me this isn't the biggest troll in the history of the internet? Cause it sounds like shoehorning DNS /and Google/ into IP in place of, y'know, IP addresses. ]Well, you don't need addresses for clients, just for content... From the architecture page at http://named-data.net/project/archoverview/: "Note that neither Interest nor Data packets carry any host or interface addresses (such as IP addresses); Interest packets are routed towards data producers based on the names carried in the Interest packets, and Data packets are returned based on the state information set up by the Interests at each router hop." So it's basically suggesting a NAT-like table in every single router. And we all know how well NAT boxes scale...
Well, as I suggested, I didn't think it was nearly that easy to do. It sounds to me like they want to put *Google* in every router. Cause no one who posits this stuff has, apparently, ever had to do network diagnosis. You put too much distributed state in the network and it comes apart. We're nearly there now with IPv4.
