A New GRASP Objective Option as an example is defined as follows, according to
draft-ietf-anima-asa-guidelines-01.
- name: s-deployment-value, which is need to be assigned by IANA registration
- objective-flag: F_DISC and F_SYNCH
- objective-value: a data structure as follows
-- s-identification, which is used to distinguish different network services
-- s-deployment-type, which indicates that it is new, or updated, or deleted
-- s-resource-information, which are the assured resources of the network
service.
-- resource-type, which indicate bandwidth, or latency, etc.
-- resource-value, which indicate the value.
-- s-deployment-status, which indicate deployment success or failure, and the
reason for the failure
Do you think it is available?
Best wishes,
Joanna

I don't know if you should combine SPE/UPE/PE. I don't know enough about this
area of traffic engineering.

I suggest you pick a name, and put it into the IANA considerations.
[JD] I fully agree with you.

Probably, just don't be so specific about the values.
I think that "object-value" can be any amount of CDDL that want to write.
You could use a map for "service-identification"
Since it's all encoded in CBOR, you can't have a 3-bit value, only a 1-byte
value.
[JD] I need to learn this definition. Hopefully, I'll understand in a few days.
> You probably mean to say that it uses the security provided by the ACP.
JD> Yes, do you think whether it is enough?
Yes, I think it is, but you need to say so, and explain what threads there are,
and why the ACP provides an acceptable solution.
[JD] I thought it was relatively simple. This scenario requires the GRASP
protocol. The security risks are mainly in the channels between autonomic
nodes.

I think that you need to explain more of it.
[JD] I try to write more about it.

I don't have the background in traffic engineering to know.
