Hi R,
Thanks for your comments.
1. The solution in this draft is compliant with the SR architecture and design
principles. The SR path selection is still in the ingress node. The End.NRP SID
can be used to build SR path at the ingress node similar to the End.X SID.
2. The End.X cannot provide the capability of forwarding resource guarantee
which is often required by some important customers. According to the
description in Section 4.2 of RFC 8986, End.X forwards to an endpoint with
cross-connect to a 39layer-3 adjacency39. While, the End.NRP can be associated
with the both adjacency and forwarding resources.

Action:draft-cheng-spring-srv6-resource-programming-00.txtDear WG,This draft is
one more attempt to shift SR path selection from ingress node to segment
endpoints.
Is such direction really something Spring wg endorses ?
Functionally all of this type of proposals can be done on ingress nodes making
transit nodes lean and carrying less state just using End.X to direct to
segments.
Just a general observation ....
Thx
R.

A New Internet-Draft is available from the on-line Internet-Drafts
directories. Title : Network Resource Programming with SRv6

Date : 2022-07-11 Abstract: This document defines a new SRv6
network function which can be used for SRv6 Network Resource Programming. A
new SRv6 Endpoint behavior is used to associate with a set of network
resource partition, called End.NRP. By using the End.NRP SID , the SRv6
policy can provide the capability of network resources programming. The IETF
