John:
For discussion at the interim: +1 to John’s belief we agreed upon customer facing rather than client. +1 to John’s concept of specifying separate action that use/manipulate capabilities from monitoring functions. My comment is practical and design-based. Practical: The monitoring and telemetry information is undergoing substantial growth in the IETF standardization, and the industry. It is important to let the capabilities grow separately. Design based: These are orthogonal functions. Why should we mix them?

Lopez Subject: Re: [I2nsf] Terminology discussion #2: "capability" & "capability interface" Hi Linda, >From the Terminology I-D: Client-Facing Interface: See Consumer-Facing Interface. See also: Interface, NSF-Facing Interface. Consumer-Facing Interface: An Interface dedicated to communication with Consumers of NSF data and Services. This is typically defined per I2NSF administrative domain. See also: Interface, NSF-Facing Interface. NSF-Facing Interface: An Interface dedicated to communication with a set of NSFs. This is typically defined per I2NSF administrative domain. See also: Interface, Consumer-Facing Interface. Therefore, 1) I'll bring this up in tomorrow's telecom, but I was pretty sure we had previously decided to use **consumer**, not **client** 2) The point of having a separate Capability Interface is to separate actions involving using and manipulating capabilities from other actions, such as monitoring. This is because capabilities are mechanisms that reflect all or part of the functionality of NSFs. As such, they are the building blocks for configuration and monitoring; this seemed to me to warrant a separate interface for security reasons. best regards, John On Mon, Sep 12, 2016 at 10:27 AM, Linda Dunbar <[email protected]> wrote: As the I2NSF Terminology has defined two types of the “capability”: - the “capability” from NSFs and - the “capability” from controller (i.e. as the response to Client’s inquiry). I find it not necessary to have the “capability interface” as we already have Client Facing interface and NSF facing interface. Capability: Defines a set of features that are available from a managed entity (see also I2NSF Capability). Examples of "managed entities" are NSFs and Controllers, where NSF Capabilities and Controller Capabilities define functionality of an NSF and about Controller, respectively. These functions may, but do not have to, be used. All Capabilities are announced through the Registration Interface. Linda -- regards, John
