Hi Xiaohu, I see similarities with my http://tools.ietf.org/html/draft-frejborg-hipv4-01, which also fit into strategy A and B. And when that happens the outcome is that it will also fit into strategy C, the RIB is reduced.
I assume that you are thinking that the addressing scheme is broken because it is flat, perhaps we need a new strategy where proposal like ours could fit into. IMO, Internet is not obeying today Rekhter's law ""Addressing can follow topology or topology can follow addressing. Choose one" because the addressing scheme (I refuse to use structure here) is flat and the routing topology is hierarchical. So proposals that are going after the addressing scheme should have an own strategy in Tony's draft. How to fix that is a technical issue and other strategies can be used to develop a hierarchical addressing structure. I believe that there are two major approaches - keep the flat globally unique addressing scheme, is it IPv4 or IPv6 makes no difference, and try to solve the problem with new routing paradigms - create a new addressing structure and try to keep the current routing topology, is it IPv4, IPv6 , HIP, etc is irrelevant at this moment All other addressing/location solutions that I can think of do have a hierarchical structure with two or more layers - there was another scheme but it got trashed in 1492. So must the addressing structure of Internet really be flat??? If it must, please advise. -- patte On Fri, Mar 13, 2009 at 11:49 AM, Xu Xiaohu <[email protected]> wrote: > In fact, the RANGI proxy borrows some idea from the map&encap approach to > support communication between RANGI-aware hosts and legacy IPv4/v6 hosts.
