"Long time" > ought to have a better spec than say, Internet Dog Years? Bill, What you say is true. Technology is going to progress, and at some point in the future we may convince ourselves that we can safely handle 1,000,000 TLAs instead of 10,000. However: 1) We are not there yet. Andrew Brodnik et al demonstrated that one can efficiently compress today's routing tables in the cache of a Pentium chip. But their algorithm has yet to be implemented in commercial routers. 2) There is more to scaling than routers' caches. Compressing the tables in cache memory mainly allows you to switch packets faster than if your tables were kept in a slow RAM. It does not reduce route flaps, or the complexity of the topology. 3) In any case, we are taking decision today based on today's technology. As I pointed out, there is plenty of address space reserved for further use. If the technology does evolve, then it will be time to open more space. In short, limiting the size of TLA to 13 bits looks like a reasonable cut, today. -- Christian Huitema

Daniel said: I have seen some of this discussion. I am afraid I have seen no documented discussion revealing the reasoning behind fixing the TLA length and fixing it at 13 bits. Frankly I have been surprised by the sudden speed of the provider based addressing standardisation. last year in regards to what is now RFC 2050 I asked the lawyers that do work for the IESG what restrictions in flexibility we (the IETF) have in the area of defining rules and technology that restricts ISP practices. I was told that the only time we can be restrictive is when there is no other technically reasonable option - I support Daniel here, if this field is to be restricted to a specific length then we must have very good technical reasons for doing so.

Daniel, There were two basic arguments for limiting the length of the TLA prefix: 1) Routing table size. All TLA have to be in all tables in all defaultless routers. Thus, the number of TLAs becomes a minorant of the size of the tables. 2) Address space size. The current document only specifies 1/8th of the address space. If it turns out that there is a need for many more TLA's in three years, it will actually be possible to make some. The particular value chosen, 13 bits, as only one advantage. The combination of format and TLA fits in 16 bits, which provides for easy writing of routing prefixes. The point that you note re: allocation practices is, however, perfectly true. ISPs should not receive a TLA 'a priori", they should graduate to it. If I remeber correctly, an ISP that starts operating in Europe today receives a /19, and will gradually receive more space as it connects more customers. An ISP that starts operating with IPv6 should receive one or several NLAs from established transit providers; it should only receive a global entry in the routing tables once it has passed some "graduation" criteria. -- Christian Huitema
