LISP for the Mobile Network
draft-farinacci-lisp-mobile-network-03
Abstract
This specification describes how the LISP architecture and protocols
can be used in a LTE/5G mobile network to support session survivable
EID mobility. A recommendation is provided to SDOs on how to
integrate LISP into the mobile network.

1. Introduction
The LISP architecture and protocols [RFC6830] introduces two new
numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
(RLOCs) which provide an architecture to build overlays on top of the
underlying Internet. Mapping EIDs to RLOC-sets is accomplished with
a Mapping Database System. By using a level of indirection for
routing and addressing, separating an address identifier from its
location can allow flexible and scalable mobility. By assigning EIDs
to mobile devices and RLOCs to the network nodes that support such
mobile devices, LISP can provide seamless mobility.
For a reading audience unfamiliar with LISP, a brief tutorial level
document is available at [I-D.ietf-lisp-introduction].
This specification will describe how LISP can be used to provide
layer-3 mobility within and across an LTE [LTE401-3GPP] [LTE402-3GPP]
