Bill - Sorry for responding late...
(1) Localized mobility support within an edge network, because theaddress indirection alone tracks host mobility only at the granularityof edge networks, not access links.(2) Dynamic and per-host mappings between edge and transit addresses,because the mapping for a single edge address changes when a mobile host moves to another edge network(3) Trust relationships between edge networks so that a mobile host'smapping can be changed by (or based on information of) a visited edge networkI'm okay with your first two points but the third makes an assumption that might not be warranted. You do need a trust relationship but it doesn't necessarily need to be between edge networks. The trust relationship can also be from the edge networks to one or many third-party address authorities.
You are raising an interesting point. 3rd-party authorities are typically used for authentication. But apart from authentication, there needs to be a trust relationship between two edge networks based on which one of the two can update a mapping on behalf of the other. Having such trust be transitive through the 3rd party would be an option, but maybe not a desirable one... - Christian -- to unsubscribe send a message to rrg-request@psg.com 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
