Abstract

   This document presents a gap and solution analysis for end-to-end
   privacy enabled mapping systems.  Each of the identifier locator
   separation system has its own approach to mapping identifiers to the
   locators.  We analyse all these approaches and identify the gaps in
   each of them and do a solution space analysis in an attempt to
   identify a mapping system that can be end to end privacy enabled.

1.  Introduction

   Identifier Locator Systems like ILA [I-D.herbert-intarea-ila], LISP
   [I-D.ietf-lisp-rfc6830bis]  [I-D.ietf-lisp-rfc6833bis] and others are
   proposed as alternative approaches to enabling direct routing in the
   upcoming converged communication networks such as 5G core network
   (5GC) rather than using tunneling with GTP-U, GRE, (P)MIPv6 or
   similar ones.  In addition to increasing packet overhead due to
   encapsulation that may cause fragmentation and all related issues
   typical disadvantages of (especially static end-to-end) tunneling
   comprise inflexibility to properly react to dynamic changes of end
   points and potential on-path anchors.  Added complexity in case of
   multicast traffic and increased signaling for tunnel management are
   further drawbacks.  Tunnels may introduce vulnerabilities or add to
   the potential for receiver overload and thus DOS attacks [draft-ietf-
   intarea-tunnels-08].  Finally without other measures such as deep
   packet inspection optimization of paths according to network
   resources and application needs becomes complex.

   With the Id-Loc systems a mapping system needs to be established so
