Hi, In this revision, I have tidied the text. That involved: - Fixing inconsistent editorial standards between the source documents - Some more minor editorials - Moving a couple of sections around - Collapsing a little duplication arising from pulling text from two places - Removing cross-references between the source documents - Removing the tagging of the source material In doing so, there were two small paragraphs that didn't seem to belong. These can be seen in the Appendix. ACTION: All: Please shout if you believe this text should not be deleted. While this document is now in a condition that can be reviewed and commented on, I propose to make some suggestions to reduce and consolidate the text. I will bring these to the list as separate threads (some have already been seen on the list, but we should make the proposed changes clear). They will cover: - Discussion of realisation. This should be a discussion of architectural realisation, not of underlying technologies. Currently we have: - a large section on ACTN - a couple of references to VPN+ - no mention of the architecture underlying draft-bestbar-teas-yang-slice-policy I already suggested (on list) a way to reduce the ACTN text, but it has since been proposed to me that all discussion of realisation of the architecture can be best achieved with brief paragraphs and references. I will propose text. - Isolation and "unmeasurable SLOs" This has long been a contentious topic. I think we had reached a bit of a compromise in the definitions draft, but doing the merge has caused me to re-read it and I am uneasy. I will be making a text suggestion to clarify the purpose and meaning of the section on isolation, and that will depend on us also clarifying the description of "directly measurable SLOs" and "indirectly measurable SLOs. - Revisiting the definition of a network slice This is obviously pretty core to our work! John Drake previously sent a suggestion to the list (2021-04-03). This caused a bit of discussion and raises a number of points. I plan to try to tease out the various points to see whether we can agree them Separately and then come up with new definitions text. This may be a good topic For our first telechat on the document. ACTION: Chairs: Decide what the rules are for having telechat meetings for this document.

This draft is a work item of the Traffic Engineering Architecture and Signaling WG of the IETF. Title : Framework for IETF Network Slices Authors : Adrian Farrel Eric Gray John Drake Reza Rokui Shunsuke Homma Kiran Makhijani Luis M. Contreras Jeff Tantsura Filename : draft-ietf-teas-ietf-network-slices-01.txt Pages : 33 Date : 2021-04-16 Abstract: This document describes network slicing in the context of networks built from IETF technologies. It defines the term "IETF Network Slice" and establishes the general principles of network slicing in the IETF context. The document discusses the general framework for requesting and operating IETF Network Slices, the characteristics of an IETF Network Slice, the necessary system components and interfaces, and how abstract requests can be mapped to more specific technologies. The document also discusses related considerations with monitoring and security. This document also provides definitions of related terms to enable consistent usage in other IETF documents that describe or use aspects of IETF Network Slices.
