                Scenarios for Flexible Address Structure
           draft-jia-scenarios-flexible-address-structure-00

Abstract

   Along as the adoption of TCP/IP in increasingly emerging scenarios,
   challenges emerge as well due to the ossified address structure.  To
   still enable TCP/IP for networks that previously using exclusive
   protocols, a flexible address structure would be highly preferred for
   their particular properties.  This document describes well-recognized
   scenarios that typically require a flexible address structure, and
   states the requirements of such flexible address structure.

1.  Introduction

   As the unified protocol of the network layer, Internet Protocol (IP)
   constantly promotes the prosperity of the entire Internet.  With the
   success of TCP/IP protocol stack, IP is gradually replacing exclusive
   protocols and becomes the core protocol of the entire communication
   system.

   Along as the popularization of TCP/IP, increasingly scenarios long
   for a flexible address structure.  To fulfill the reachability, IP
   address is designed to hold the topology semantic only [RFC0791].
   While within limited domains (ref.  [RFC8799]), a multi-semantic
   address could be increasingly preferred in implementing complex
   actions and capabilities for particular scenarios.  Under such
   circumstances, a flexible address structure can unleash more
   possibilities in serving new scenarios.

   This document describes well-recognized scenarios that typically
   require a flexible address structure, and states the requirements of
   such flexible address structure.

2.  Flexibility: Potential Orientation

   Since a flexible address is expected be adaptive with different
   scenarios and routing abilities,
   potentially orientations of a flexible address structure should
   include multiple semantics.  According to the definition of IP
   structure [RFC1180], cyberspace topology location serves as the only
