Separating identifier from locator with extended DNS

Although most researchers have agreed that the locator/identifier separation is beneficial for the Internet, there is no consensus on how to define the “identifier”. In this paper, we propose a scheme in which identifiers are distributed by authorities to endpoints, and the authorities are responsible for maintaining real-time locators of endpoints with identifiers they distributed. This scheme can be helpful to accounting, security and other network management tasks. We also present in details how to implement this scheme with extended DNS and a new infrastructure, i.e., ID Mapping System (IDMS).
