Sure. Agreed. I know, we can only express our personal opinions and see what might happen. Heiner

Mai. 2010, 11:18 Thema: RE: [rrg] RG futures I would simply turn off non-link-local multicast (on most routers it's not even on...) and return class D and class E addresses to the allocatable pool. If this leads to a bonus upgrade of router equipment across the Internet - well, that's one way to ensure other protocols (e.g. IPv6) are available for use.

Approx. a billion of addresses could be made available for unicast (as to relax the Ipv4 address depletion problem) by means of 1 Multicast-Protocol Type combined with the sender’s unicast address as to replace the multicast address. In case the counter argument were “this undermines all the deployed multicast solutions” then I would add “good so” (see next). 4) Multicast forwarding I heavily question ALL existing multicast solutions. I am also wondering why multicast doesn’t play any role at all in the RRG-discussion. My proposed solution would be “cascade tree forwarding”, enabling state-less multicast to approx. 99,9 % of the involved routers. It is the combination of all these holy cows which blocks the view to a brighter routing technology, where there is no discrepancy between intra- and inter-domain routing, nor between CES and CEE, and where better technological tools would be given to the hands of the next generation of students.
