Hello Authors,
Please consider the following comments:
I. draft-ooamdt-rtgwg-oam-gap-analysis-00
1) Security Considerations: Text does not reflect the scope of this work.
2) Sec 2.3: Is Telemetry being considered in scope of this work? What is the
motivation of this section in this document?
3) Sec 2.1.1.3 Not sure about the term SFP, Can you please explain/ expand it.
4) Sec 2.1.1.1. Proactive CC/CV in BIER: What is the motivation in specifying
the packet formats (specifically for BIER, when other sections don't have
similar figures)?
II. draft-ooamdt-rtgwg-ooam-requirement-00
1)
It may be nice to define a generalized layer model based on which the
requirements are derived, while the layering may be specific to an overlay like
NVO3/ EVPN the generic model may try to bring out the common aspects across the
different technologies.
2)
Since there are specific sections to capture FM and PM requirements, it may be
better to specify the respective requirements in their sections instead of
clubbing them together. e.g. The following requirements seem to be candidates
for this.
REQ#4: Overlay OAM MUST support proactive and on-demand OAM
monitoring and measurement methods.
REQ#5: Overlay OAM MUST support unidirectional OAM methods, both
continuity check and performance measurement.
3)
The requirement below may be a hard one to realize and limit the scalability of
the solution.
REQ#14: Overlay OAM MUST have the ability to discover and exercise
equal cost multipath (ECMP) paths in its transport network.
4)
The requirement below may not hold true for multicast OAM,
REQ#7: Overlay OAM MUST support bi-directional OAM methods. Such
OAM methods MAY combine in-band monitoring or measurement in
forward direction and out-of-band notification in the
reverse direction, i.e. from egress to ingress end point of
the OAM test session.
It may be worthwhile to consider separating requirements for unicast and
multicast separately.
5) Sec 4.3 AIS requirements: Can this section be merged with Sec 4.1 (FM
requirements)
6) Sec 4.4: The term survivability may need some definition. If it is already
defined in an earlier document, it may be nice to have a reference to it.
Thanks
Prasad
