There are many bits of "where" information which are not allocated to specific edge attachment points. We can name them, but for now the most important thing is that NOT ALL bits of 'where' information are 'locators'. Locators should be restricted to being names allocated to specific edge attachment points and should not include group addresses or any other abstractions. However, just because a piece of 'where' information is not a locator doesn't mean it has to be an identifier either. > "forwarding selector", "f-selector" - The field in the packets which the > routers look at to decide where to send the packet next.

Actually since this is the new millennium, a forwarder can a number of forwarding selectors, not just one. _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
