Framework for IETF Network Slices
draft-nsdt-teas-ns-framework-05
Abstract
This memo discusses setting up special-purpose network connections
using existing IETF technologies. These connections are called IETF
network slices for the purposes of this memo. The memo discusses the
general framework for this setup, the necessary system components and
interfaces, and how abstract requests can be mapped to more specific
technologies. The memo also discusses related considerations with
monitoring and security.
This memo is intended for discussing interfaces and technologies. It
is not intended to be a new set of concrete interfaces or
technologies. Rather, it should be seen as an explanation of how
some existing, concrete IETF VPN and traffic-engineering technologies
can be used to create IETF network slices. Note that there are a
number of these technologies, and new technologies or capabilities
keep being added. This memo is also not intended presume any
particular technology choice.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on 6 August 2021.

1. Introduction
This draft provides a framework for discussing IETF network slices,
as defined in [I-D.ietf-teas-ietf-network-slice-definition] It is the
intention in this document to use terminology consistent with this
and other definitions provided in that draft.
In particular, this document uses the following terminology defined
in the definitions document:
