Alternate-Marking Method (AMM) is a technique used to perform packet loss, delay, and jitter measurements on live traffic. This document defines a YANG data model for Alternate Marking Method.¶

Alternate-Marking Method ([RFC9341] [RFC9342]) is a technique used to perform packet loss, delay, and jitter measurements on live traffic. [RFC9343] defines how to encode Alternate-Marking information in IPv6 Extension Header. [I-D.ietf-mpls-inband-pm-encapsulation] defines how to encode Alternate-Marking information in MPLS Label Stack. This document defines a YANG data model for alternate marking method.¶
This section presents a simplified graphical representation of the AMM data model using a YANG tree diagram [RFC8340].¶
