[ippm] 回复：Re: update "draft-he-ippm-integrating-am-into-ioam"

Hi, Xiao Min,

Thank you for the question and concern.

Regarding the IOAM Trace Option, a passport-based IOAM, I think it is difficult for its extension supporting Alternate Marking method. 

Because in IOAM Trace Option mode, the IOAM data is pushed into data packets by every transit node until the IOAM decapsulating node &nbsp;(destination node) removes IOAM-Option-Type from packets and send the IOAM data to a receiving entity for analysis.

The Alternate Marking method demands that the network support Hop-by-Hop option or End-to-End option. In &nbsp;Hop-by-Hop mode, &nbsp;packet&nbsp;drop and packet drop location can be monitored accurately (which hop the loss occurs) , and End-to-End mode can only monitor packet loss (from source to destination).

So, the IOAM DEX Option, also called the postcard mode, is quite suitable for incorporating the Alternate Marking method.

Best Regards,

Xiaoming

Hi Xiaoming He, authors,

Thank you for the interesting draft.

While reading this draft, a question raised in my mind, is it possible to extend IOAM Trace Option except for IOAM DEX Option?

AFAIK, IOAM Trace Option and IOAM DEX Option have different application scenarios, so it seems to me it's helpful to combine IOAM Tracing with Alternate Marking when IOAM Trace Option is preferred.

Best Regards,

Xiao Min

Title:&nbsp;&nbsp;&nbsp; Integrating the Alternate-Marking Method into In Situ Operations, Administration, and Maintenance (IOAM)

Abstract:

&nbsp;&nbsp; In situ Operations, Administration, and Maintenance (IOAM) is used
&nbsp;&nbsp; for recording and collecting operational and telemetry information.
&nbsp;&nbsp; Specifically, passport-based IOAM allows telemetry data generated by
&nbsp;&nbsp; each node along the path to be pushed into data packets when they
&nbsp;&nbsp; traverse the network, while postcard-based IOAM allows IOAM data
&nbsp;&nbsp; generated by each node to be directly exported without being pushed
&nbsp;&nbsp; into in-flight data packets.&nbsp; This document extends IOAM Direct
&nbsp;&nbsp; Export (DEX) Option-Type to integrate the Alternate-Marking Method
&nbsp;&nbsp; into IOAM.

Any comments and questions are welcomed.
