I still assume we're talking about "pure" identifiers ... Since it is very hard to guarantee global uniqueness (unless they are aggregated), I would not use them to look up locators, nor as the sole authentication mechanism after a connection is established. > If no, then they purely function on the transport and higher layers and > have no relationship to the network layer so they might as well not > exist for our purposes. They are not part of routing and forwarding per se, but if a routing and addressing approach has the headers carrying something that is useful as an identifier, that's to be noted. > If yes, they need to have some hierarchy or have a very low granularity > so their total number remains low in order to make the lookup function > scale. true Scott -- to unsubscribe send a message to [EMAIL PROTECTED] with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
