The point you seem to miss is: There is no such thing as lucky design. You get exactly what you want.<br><br>IPv6 was not deployed to co-exist with IPv4. A worldwide transition was assumed. So they do not co-exist<br>efficiently.<br>
<br>Is the worldwide transition to IPv6 is a good thing? <br><br>It is assumed that the need for IP addresses is homogeneously distributed over the world. In reality, some <br>entities need much less addresses than others. So worldwide transition to IPv6 doesn't make sense. <br>
The problem here is: You design a protocol, but you do not give the freedom of choice to use this protocol. <br>Those who need it cannot use it. Because there are entities who do not need it. <br><br>Another problem with imposing the same protocol to the whole world is the assumption that the product is <br>
perfect for everybody. It is probably not. I don't want 6lowpan for my sensor network for example because <br>the IP address is too large. I want IPv7 which defines very small IP packets, for example. Who can say no?<br>
I want to test IPv8 in my country. Who can say no?<br><br>IPv6 means: IP research is done forever. IPv6 is good for everyone. I am sorry, this is impossible.<br><br>**********<br>Who says that IETF has the role of designing IP versions for the entire world? This is the most important problem.<br>
I can design one and use it. Who will say no? I am happy with my IP and I want to be reachable to the entire <br>world. <br>**************<br><br>IETF's role is to enable technology, i.e. all possible IP protocols. Everybody do what they wish.<br>
<br>As I see, we should have a dynamic IP layer which allows all solutions, we see what happens. Who knows everybody<br>may agree on the same version for some time, then disagree again. <br><br>The question is, without entering design challenges, is this what we want? I seriously doubt that IETF did not<br>
ask itself what it wants really. I questioned MANET for example, I told that it is useless. No one could explain why<br>it is useful. Millions of dollar are being spent for MANET research. <br><br>-- <br><a href="http://www.content-based-science.org" target="_blank">http://www.content-based-science.org</a><br>
