Re: And Now for Something Completely Different (was Re: IPv6 news)
How is a split between locator / identifier any different logicaly from the existing ipv4 source routing?
IPv4 source routing, as it exists today, is an extremely limited mechanism for specifying waypoints along the path to the destination.
This is completely orthogonal to a real identifier/locator split, which would divide what we know of as the 'address' into two separate spaces, one which says "where" the node is, topologically, and one which says "who" the node is. One might use the identifier in the TCP pseudo-header, but not the locator, for one example, immediately allowing both mobility and multi-homing.
