Hi Thomas,
I have reviewed draft-ietf-opsawg-ipfix-gpon-gem, and have the following
comments,
This draft mainly use information such as the PTI and GEM PORT-ID in the GPON
protocol frame, integrating them into IPFIX to distinguish between service
flows and management flows like OMCI. However, I am not very clear about the
value of this approach and have the following questions:
1. In the GPON protocol frame, PTI is used to indicate whether a frame is
a service frame or an OAM frame, and it also serves as a fragmentation
identifier within the GPON protocol. However, this identifier was deprecated in
the subsequent 10G-PON, how do you consider this discontinunity? .
2. The OAM frames identified in the GPON protocol essentially represent
OMCI management information. However, the transmission and processing of this
management information are confined to the GPON protocol stack software between
the OLT and ONU. Therefore, if such information is placed into IPFIX, it is
unclear whether it can be utilized for subsequent network transmission phase.
Could you elaborate on the value of doing so?
Best regards
Chongfeng
