ABSTRACT Evaluating the Benefits of the Locator/Identifier Separation ∗

Since recent years, it has been recognized that the existing routing architecture of today’s Internet is facing scalability problems. Single numbering space, multi-homing, and traffic engineering, are making routing tables of the default free zone to grow very rapidly. Recently, in order to solve this issue, it has been proposed to review the Internet addressing architecture by separating the end-systems identifiers ’ space and the routing locators ’ space. In this paper we review the most recent Locator/ID separation proposal and explore the benefits that such an architecture may bring. In particular, we evaluate the improvements that can be achieved in terms of routing tables ’ size reduction and traffic engineering. Categories and Subject Descriptor
