The Locator/ID Separation Protocol (LISP), proposed by Cisco
and currently under standardization at the IETF (Internet Engineering Task Force), is an instantiation of the paradigm separating locators and identifiers. LISP improves Internetu2019s scalability, also providing additional benefits (e.g., support for multi- homing, traffic engineering, mobility, etc.) and having good incremental deployability properties. The talk will overview the principles of LISP, its use in context different from Internet scalability, and some of the ongoing work in Telecom ParisTech.
