        Mobility Management Using Identifier Locator Addressing
                     draft-mueller-ila-mobility-03

Abstract

   This specification describes a new mobile network architecture which
   improves mobility management using Identifier Locator Addressing ILA)
   in IPv6 for next generation mobile telecommunication networks such as
   5G and Mobile Edge Clouds. Identifier-locator addressing
   differentiates between location and identity of a addressable network
   element, which can be a mobile device or a data center task. The
   approach presented in this draft enables mobility management on Layer
   3, and provides a simplified, GTP-tunnel-free and more efficient
   architecture with less core network utilization compared to
   traditional architecture.
