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
