Hi，
IMO, if the user equipment can join in and support the GRASP, it would be
helpful.
The user equipment can not support RSVP, which is complex.
Perhaps it can support a simpler way to communicate the resource
requirements to the network, and make sure the network can fulfill its
requirements.

Subject: [Anima] GAP Analysis and Requirements of Resource-based Network
Services Deployment
Hi,
In the previous mailing list, our discussion in the mailing list basically
focused on the definition of GRASP. The related draft is listed in
https://datatracker.ietf.org/doc/draft-dang-anima-network-service-auto-deployment/.
In fact, the GAP analysis and requirements of Resource-based Network Services
Deployment are the most important work at present.
With the development of a large number of IoT terminal accesses and the
industrial Internet accesses, the services requirement on network resources are
becoming more and more demanding. The operator's network has made great efforts
in this regard by adopting traffic engineering and the network calculus
embedded in controller. But in fact, resource-based service deployment is an
E2E concept.
The actual network deployment still has the following problems.
1. In the campus network, not all devices might be managed by the
controller, for example, some sensors have limited computing and storage
resources and cannot consume too heavy mechanisms. Or devices of different
vendors might not communicate with one controller for various reasons. At this
time, a distributed mechanism is needed to transfer related resource
information.
2. RSVP is a very good resource reservation protocol, but it is coupled
with MPLS. Moreover, the protocol has no way to deal with other resource
information (such as the delay information). Also, is the RSVP too heavy in the
campus network or the end user?
3. Compared with the operator's network, the campus network has more
uneven resources. Actually, some nodes may have resource guarantee
requirements, such as wireless connections.
4. The end user and network lack of the resource-based self-adapting
mechanism.
5. … ( Welcome to enrich / optimize / modify them )
6. …
For the above reasons, I have started to write this draft and try to use GRASP
to solve parts of the above problems. This draft is now in its rudimentary
form and rough, and it might not fully express my thoughts. So I specially
write this email.
I strongly hope to listen your opinions, and am looking forward to your reply.
Best wishes,
Joanna
