Hi Eliot, In the "Re: [rrg] Next pass" thread, regarding incentives to deployment, you wrote, in part:

A month ago I wrote about Ivip's new Distributed Real Time Mapping (DRTM) system - which is also applicable to LISP: http://www.firstpr.com.au/ip/ivip/drtm/Ivip-DRTM.pdf This is 3,300 words - about the same amount of text as the last 9 messages in the "Next pass" thread. There are three diagrams too. http://www.firstpr.com.au/ip/ivip/drtm/Ivip-DRTM-Fig-1.pdf http://www.firstpr.com.au/ip/ivip/drtm/Ivip-DRTM-Fig-2.pdf http://www.firstpr.com.au/ip/ivip/drtm/Ivip-DRTM-Fig-3.pdf DRTM shows initial, substantial, deployment without any investment by ISPs, other than accepting packets from their SPI (Scalable PI) using end-user networks where the source address is from the "edge" subset of the address space. (In LISP, this would be an "EID" address in the source field.) There is no need for ISPs to install ITRs or ETRs. They can do this, and after a while, there are motivations for them to do so - at least with ITRs. It doesn't take an economist to quantify the initial investment by ISPs, because there is none. The investment comes from those who benefit directly and immediately: the companies which lease out SPI space from the Mapped Address Blocks (MABs) they run, and by the end-user networks who lease this space and pay other fees to use it. These organisations have an immediate incentive to deploy the new system, since they get immediate substantial benefits. The adopting networks get full use of their new SPI space - all incoming traffic is handled by ITRs (initially the DITRs run by the companies which run the MABs). This is full benefits right from the start for all adoptors - not in proportion to how many other networks adopt it, as with Core-Edge Elimination (ILNP etc.) architectures. - Robin _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
