Phillip, > My personal view is that we should develop an Internet architecture that allows an infinite number of new protocols to be deployed without consumption of scarce resources, i.e. port numbers of DNS RRs. ... > So in summary, the IAB should be charged with identifying the set of finite resources that IANA assigns and propose an Internet architecture in which deployment of new application layer protocols does not cause any of the finite resources to be depleted. > I'm definitely in favor of improving the situation. And for applications protocols this is probably an easier problem to begin with. And as I said in the previous e-mail, as far as I know, most new work uses field sizes and types that have less scarcity. However, the Internet runs to a large extent on protocols that were designed decades ago, and some of those protocols have number spaces that are very finite. I don't want to run out of protocol numbers, DHCP message types, etc. Jari _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
