Optional Advanced Deployment Scenarios for the
Identifier-Locator Network Protocol (ILNP)
Abstract
This document provides an Architectural description and the Concept
of Operations of some optional advanced deployment scenarios for the
Identifier-Locator Network Protocol (ILNP), which is an evolutionary
enhancement to IP. None of the functions described here is required
for the use or deployment of ILNP. Instead, it offers descriptions
of engineering and deployment options that might provide either
enhanced capability or convenience in administration or management of
ILNP-based systems.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Research Task
Force (IRTF). The IRTF publishes the results of Internet-related
research and development activities. These results might not be
suitable for deployment. This RFC represents the individual
opinion(s) of one or more members of the Routing Research Group of
the Internet Research Task Force (IRTF). Documents approved for
publication by the IRSG are not a candidate for any level of Internet
Standard; see Section 2 of RFC 5741.
