A couple of minor nits: (1) p 2, sec 1. Introduction This document presents sample use cases for DOTS Telemetry, which makes concrete overview and purpose described in [RFC9244]: what components are deployed in the network, how they cooperate, and what information is exchanged to effectively use attack-mitigation techniques. I found this sentence hard to parse. (2) p 5, sec 3.1.1. Mitigating Attack Flow of Top-talker Preferentially The forwarding nodes send traffic statistics to the flow collectors, e.g., using IP Flow Information Export (IPFIX) [RFC7011]. When DDoS attacks occur, the flow collectors identify the attack traffic and send information about the top-talkers to the orchestrator using the "target-prefix" and "top-talkers" DOTS telemetry attributes. The orchestrator then checks the available capacity of the DMSes by using a network management protocol, such as Simple Network Management Protocol (SNMP) [RFC3413] or YANG with Network Configuration Protocol (YANG/NETCONF) [RFC6020]. Please use RFC 7950 as the reference for YANG. Please check other references. Regards, Rob
