Information and Data Models for Packet Discard Reporting

This document defines an Information Model and specifies a corresponding YANG data model for packet discard reporting. The Information Model provides an implementation-independent framework for classifying packet loss - both intended (e.g., due to policy) and unintended (e.g., due to congestion or errors) - to enable automated network mitigation of unintended packet loss. The YANG data model specifies an implementation of this Information Model for network elements with a focus on the interface, device, and control-plane discards.
