Hi Roland,

locator A locator is a name that has topological sensitivity and must change if the point of attachment changes.A locator is defined as a designator which has topological significance and provides reachability information for endpoints; the locator(s) associated with an endpoint change if/when the point(s) of attachment of an endpoint within the network topology changes.
Hmmm.... I have to take issue with the reachability information. It is the presence of a locator (or its abstraction -- the prefix) in a particular protocol that conveys reachability, not the locator itself.
identifier An identifier is the name of an endpoint. It has no topological sensitivity. That is, the identifier will not change, even if the endpoint changes its attachment within the topology. Identifiers may have other properties, such as the scope of their uniqueness (global or local) and the probability of their uniqueness (absolute or statistical).An identifier is the designator of an endpoint; identifiers have no topological significance, and do not change even if the endpoint changes its point(s) of attachment within the network topology. Identifiers may exhibit other properties such as global uniqueness, local uniqueness (for varying definitions of 'local'), absolute uniqueness, statistical probability of uniqueness, etc.
Thanks, I like the wording here and have merged it. Tony _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
