Hi Adrian and All, >I agree with Loa, moving the definition of how the term "customer" is interpreted in the document to the Terms and Abbreviations section seems very reasonable. +1 I don't stick to "customer", but a discussion how about rephrasing "provider" with "producer" may also rise when I choose non-ietf-standard "consumer" term, Related to this, should we rephrase " IETF Network Slice user" if there is any intention to leave? 5.2. Expressing Connectivity Intents The NSC northbound interface (NBI) can be used to communicate between IETF Network Slice users (or customers) and the NSC. An IETF Network Slice user may be a network operator who, in turn, provides the IETF Network Slice to another IETF Network Slice user or customer. >the expectation currently is that the IETF Network Slice Service will use something along the lines of the service models (L2SM and L3SM). It seems reasonable to enhance those with something about service functions, quite possibly along the lines you are already working on. > > [TS] (snip) Alternatively, does it help if the NBI request expresses such inclusions/exclusions policy using/referencing a customer-centric topology that a provider may have furnished earlier to the customer, and which the provider can readily map to their FYI, L3SM tried to let the customer define such policy against PE site in sec. 6.6. I know this is non-exhaustive for IETF Network Slice. Editorials: - I'm not sure if recent RFCs should refer SNMP as an NBI in the sense of https://www.ietf.org/about/groups/iesg/statements/writable-mib-module/ . 5.2. Expressing Connectivity Intents o SNMP ([RFC3417], [RFC3412] and [RFC3414] uses binary encoding (ASN.1). o For data modeling, YANG ([RFC6020] and [RFC7950]) may be used to model configuration and other data for NETCONF, RESTCONF, and GNMI - among others; ProtoBufs can be used to model gRPC and GNMI data; Structure of Management Information (SMI) [RFC2578] may be used to define Management Information Base (MIB) modules for SNMP, using an adapted subset of OSI's Abstract Syntax Notation One (ASN.1, 1988). - multipoint-to-point twice .2. IETF Network Slice Endpoints As noted in Section 3.1, an IETF Network Slice describes connectivity between multiple endpoints across the underlying network. These connectivity types are: point-to-point, point-to-multipoint, multipoint-to-point, multipoint-to-point, or multipoint-to-multipoint. All the best, Kenichi -----Original Message----- From: Teas <teas-bounces@ietf.org> On Behalf Of Gyan Mishra Sent: Saturday, May 8, 2021 10:55 AM To: Greg Mirsky <gregimirsky@gmail.com> Cc: Adrian Farrel <adrian@olddog.co.uk>; Med Boucadair <mohamed.boucadair@orange.com>; TEAS WG <teas@ietf.org>; Loa Andersson <loa@pi.nu> Subject: Re: [Teas] Moving forward with draft-ietf-teas-ietf-network-slices I agree with Loa and am not crazy about either customer or consumer as either refers to a “human” endpoint and not a system endpoint made of hardware or software like the term “CE”. +1 for Customer over Consumer as a customer is human endpoint that has paid for service SLA where a consumer is broader term like subscriber describing for example all broadband subscriber community.

Perhaps the section can include two sub-sections - Abbreviations/Acronyms and Terms/Terminology. I've noticed that there is the forward reference in the section: The above terminology is defined in greater details in the remainder of this document. It could be those other definitions of terms used in the specific context in the document be collected in the new sub-section.

As you said it is late in the document, and really not in a definitions section. I don't know if we can we place something in Section "2. Terms and Abbreviations", but there seems to be only abbreviations. Your wholesale example: I think you forget about wholesale. What do you call the school that buys food at the shop to provide to the children? Do you call the school the customer, or do you refer to the cook who buys the food as the customer? The contract is with the school, negotiated by the cook, signed by the bursar. I think "the school! is the customer, which is OK in this context. The cook and the school kids could be viewed as consumers", one removed from the system. It strikes me that "Customer System" and "IETF Slice" are somewhat similar, the risk is that we talk about "customer" (even if we change it), and "slice" (even though if is really "IETF Slice)", Having said that, though it is not my task to call consensus, I think we have a enough support to use "customer". I rest my case. /Loa On 05/05/2021 13:05, Adrian Farrel wrote: > We currently have (in section 5.1, which may be a bit late in the document) > > Customer: A customer is the requester of an IETF Network Slice. > Customers may request monitoring of SLOs.
