Hi Yujing,
Thanks, it is clear now what you intend. Do you have the 'cddl' tool installed?
It is quite simple, but it allows you to validate CDDL syntax and generate
random examples. See Appendix F of RFC8610.
I did find a few nits.
1) CDDL does not accept tab characters. So all the tabs must be changed to
spaces.
2) If you define an element as xxx : uint, a second definition such as xxx =
0..7 is ignored.
3) service-tag-info = str should be service-tag-info = text
4) Did you mean resource-requirement-pair to be a group with () or an array
with []? I think probably you meant an array. (See section 3.4 of RFC8610.)
So my version that works with the CDDL tool is:
autonomic-network-service-value =
[
[
service-type,
service-id,
service-lifetime,
service-tag
],[
*resource-requirement-pair
]
]
service-type = 0..7
service-id = uint
service-lifetime = 0..4294967295 ; in milliseconds
service-tag = [ *service-tag-info]
service-tag-info = text
resource-requirement-pair =
[
resource-type,
resource-value
]
resource-type = 0..7
resource-value = uint
Is that OK?

Hi Brian,
Thanks for your reply, allowing me to modify the draft better.
Because of my lack of understanding of the CDDL format, some
definitions are misunderstood. I update Figure 2 according to RFC8610, and hope
this version is clearer. If there are lack of standardization, please let me
know.
-----------------------------------------------------------
UPDATE : Format of autonomic-network-service-value-value
autonomic-network-service-value = [
[
service-type : uint,
service-id : uint,
service-lifetime : uint,
service-tag
],[
*resource-requirement-pair
]
]
service-type = 0..7
service-id = uint
service-lifetime = 0..4294967295 ; in milliseconds
service-tag = [ *service-tag-info]
service-tag-info = str
resource-requirement-pair = (
resource-type: uint,
resource-value: uint
)
resource-type = 0..7
resource-value = uint

Hi,
I'm still not fully understanding the notation used in Figure 2 at:
https://www.ietf.org/archive/id/draft-ietf-anima-network-service-auto-deployment-03.html#section-5-8
There is an expansion of service-information in CDDL just below the figure, but
if you want conforming implementations, I think you need to fully expand
autonomic-network-service-value in CDDL, or define carefully how Figure 2 is to
be understood.
Regards
Brian

Title : A Generic Autonomic Deployment and Management

Abstract:
This document specifies an autonomic mechanism for resource-based
network services deployment and management, using the GeneRic
Autonomic Signaling Protocol (GRASP) defined in [RFC8990] to
dynamically exchange the information among the autonomic nodes. It
supports the coordination and consistently operations within an
autonomic network domain. This mechanism is generic for most, if not
all, of kinds of network resources, although this document only
defines the process of quality transmission service deployment and
management. It can be easily extended to support network services
deployment and management that is based on other types ofnetwork
resources.
