hi Adrian,
Some typo or comments for your consideration,
Page 10, the first line: be determined [by] the customer...
Page 12, in 4.2: the 'multipoint-to-point' is duplicate.
The IETF NSE[s] are conceptual points of connection ...
Page 12, it says,
'An NSE should be identified by a unique ID in the context of an IETF Network Slice customer.'
'A combination of NSE unique ID and NSE attributes defines an NSE in the context of the IETF Network Slice Controller (NSC).'
The unique ID of NSE is in the context (or name space) of IETF Network Slice customer. The context/name space of IETF Network slice customer may be different from the context of IETF network slice controller, considering, for example, difference customers could use different the same unique ID in their own customer contexts. It may need to consider the difference between the customer context and NSC context in order to keep the ID unique.
Page 20, 'IEFT' typo
Page 20, 'are mapped to the underlay IETF Network Slice Endpoints (NEPs)'. The abbreviation could be NSEs while not NEPs.
Page 24, security consideration, ' as some aspects of security may be expressed in SLOs.'
According to 4.1.2.1, security is expressed in SLE, and here, the SLOs could be SLEs.
Regards,
Xiaobing NIU

主 题 :[Teas] Moving forward with draft-ietf-teas-ietf-network-slices
Several important points:
1. This is work in progress and you are all allowed to comment on any of the
text. Changes made here are based on text floated on the list and comments
received, but this is NOT confirmed consensus and is still open for
modification.
2. You can see the changes this time around at
https://www.ietf.org/rfcdiff?url1=draft-ietf-teas-ietf-network-slices-01&url
2=draft-ietf-teas-ietf-network-slices-02&difftype=--hwdiff
a. Eric has retired, but is still following the work
b. No longer need the Editor's Note in Section 1
c. "Consumer" vs "customer". I have made this consistent (we only need to
use one
term). I selected "Customer" because that seemed best, but I know
some people
prefer "consumer". Please discuss if you are not happy.
d. Changes for Isolation text and introduction of "SLE" for
"unquantifiable objectives"
as proposed on the list, with edits for the comments received
e. Changes for realisation of network slices as proposed on list, with
edits for the
comments received.
f. Various small editorials
g. Fix ordering of end-matter sections
h. Remove "Unused Material" Appendix (as it was unused :-)
3. Next work topics (in no particular order)
a. Definition of a Network Slice Service (based on a discussion started
on the list by John Drake)
b. Definition of End Points (ditto)
c. Resolve "duplication" between Figure 1 and Figure 3 as well as
surrounding text
d. Propose a functional architecture for realising network slices
4. I think that at least 3d will need a meeting. If 3a or 3b gets a
significant level of
discussion on the list then it should also have a meeting. I will try to
give a week's
notice for any meeting and pick a time that works for California and
Beijing. But,
please note that you don't have to come to a meeting to have an opinion
- that is
what the mailing list is for.
Best,
Adrian

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
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-02.txt
Pages : 32
Date : 2021-05-04
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.
The IETF datatracker status page for this draft is:
https://datatracker.ietf.org/doc/draft-ietf-teas-ietf-network-slices/
There are also htmlized versions available at:
https://tools.ietf.org/html/draft-ietf-teas-ietf-network-slices-02
https://datatracker.ietf.org/doc/html/draft-ietf-teas-ietf-network-slices-02
A diff from the previous version is available at:
https://www.ietf.org/rfcdiff?url2=draft-ietf-teas-ietf-network-slices-02
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
