LISP for the Mobile Network
draft-farinacci-lisp-mobile-network-11
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.
