To the untrained eye there is a lot of overlap unless I'm not reading
correctly.

"b) Specify a new NSLP (NSIS Signaling Layer Protocol), similar to the
NAT/Firewall NSLP and QoS NSLP that can be applied and support the APONF
use cases. "

"

o) specify extensions to the IETF NSIS protocol to distribute the SFP based
network configuration and network topology models between network
management applications (e.g., OSS applications) and e.g., the network
management system, the routing controlling system or other controlling
systems. The IETF Next Steps in Signaling (NSIS) protocol may be extended
in two ways to support this interface:

a) Extend NSIS GIST to be used for off-path support"



I believe the more fragmented these initiatives are, more confusion to
IESG. The paragraphs above would be enough confusion to anyone.

SFC WG has both data plane and control plane work in the charter. Nothing
preclude to have modeling of services policies as one of the charter items
in AEON
