However, a locator/id separation without map/encap is a desirable thing that could allow the routing system to scale better. Unfortunately, we failed to address this issue when designing IPv6. It will not get correctly solved without a revision to the header design. There is no will to change the packet header in the near future. We're having too much "fun" rolling out the current one.
Hi Owen, Right problem, wrong part of the problem. As is, the IPv6 layer 3 headers have plenty of bits to do a dandy job in a loc/id separation scheme: merely strip the ID function from the IP address and push it up the stack to layer 4. The crux of the problem, then, is that ID should be maintained by the layer 4 protocol with a dynamic and changeable mapping to the layer 3 locator. We don't need a new IP. We need a new TCP.
