Abstract
Many efforts of the network research community focus on the introduction ofa new identifier to relieve the IP address from its dual role of end-hostidentifier and routable locator. This identifier-locator split introduces anew identifier between human readable domain names and routable IPaddresses. Mapping between identifiers and locators requires additionalname mapping mechanisms because their relation is not trivial. Despite itspopularity and efficiency, the DNS system is not a perfect choice forperforming this mapping because identifiers are not hierarchicallystructured and mappings are frequently updated by users. In this paper wediscuss the features needed to resolve flat identifiers to locators in asecure manner. In particular, we focus on the features and the performancethat identifier-locator split protocols require from a mapping system. Tothis end, we consider a mapping system for an identifier-locator splitbased mobility solution and evaluate its performance.
