Hi Greg, Thanks for the comments. Please see inline. Thanks, Bo 发件人: Greg Mirsky [mailto:gregimirsky@gmail.com] 发送时间: 2021年11月4日 4:03 收件人: opsawg <opsawg@ietf.org>; draft-ietf-opsawg-yang-vpn-service-pm@ietf.org 主题: A question on the use of "direction" in draft-ietf-opsawg-yang-vpn-service-pm Dear Authors, thank you for your work on this model. I read the document and have one question and a single suggestion for your consideration: * I find the description of the "direction" somewhat confusing. Can you give an example when the "direction" is set to "two-way". In that case, how that affects the reported performance metrics. I can imagine that in some cases, a performance metric calculated using a round-trip measured value. In that case, it is helpful to indicate the source of the metric as RT/2 vs. one-way. [Bo] Thanks. This makes sense. Instead of “direction” definition, I suggest to directly define “ two-way-delay”, so when the “pm-source” uses two-way measurement, it is easier to read. I may suggest changing default values for percentiles. Based on the feedback we've received, the STAMP YANG model uses p95, p99, and p99.9 as default values for low, middle, and high percentile respectively. [Bo] Thanks for the suggestion. Looking at STAMP YANG, I can’t find the description on this. Could you elaborate on why these values are defined? Regards, Greg
