Wouldn’t if be good if… IPv6 offered solutions in this space that allowed endpoint identity to be distinguished from location and forwarding functions “Second-Comer” Syndrome: This perspective can be phrased as: Unless IPv6 directly tackles some of the fundamental issues that have caused IPv4 to enter into highly complex solution spaces that stress various aspects of the deployed environment than I’m afraid that we’ve achieved very little in terms of actual progress in IPv6. Reproducing IPv4 with larger locator identifiers is not a major step forward – its just a small step sideways! “We’ve Been Here Before” Warning: Of course this burdens the IPv6 effort in attempting to find solutions to quite complex networking issues that have proved, over many years of collective effort, to be intractable in IPv4. If the problem was hard in an IPv4 context it does not get any easier in IPv6! That should not stop further exploration of the space, but it should add a touch of caution to evaluation of solutions in this space. |
