Subject: [ippm] Welcome comment on Performance Measurement on LAG

Hello All,

Performance Measurement on LAG, https://www.ietf.org/internet-drafts/draft-li-ippm-pm-on-lag-01.txt<https://www.ietf.org/internet-drafts/draft-li-ippm-pm-on-lag-00.txt>, was not presented in the past virtual meeting due to limited time. This doc defines extensions to OWAMP, TWAMP and STAMP to implement performance measurement on every member link of a Link Aggregation Group (LAG).  With the measured metrics of each member link of a LAG, it enables operators to enforce performance metric based traffic steering policy among the member links.

The requirements come from field networks, where the link delays of the member links of a LAG are different because the member links are over different transport paths.  To provide low delay service to time sensitive traffic, we have to know the link delay of each member link of a LAG and then steer traffic accordingly.

We appreciate all the comments and suggestions.

Best Regards,
Zhenqiang Li
