This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information.

The draft is describing a control framework for network interconnect testing, comprising YANG models relating to the traffic generator and traffic analyser. The draft would benefit from the addition of more introductory material to explain its applicability and potential uses, but the mechanism otherwise looks to be well-defined. This type of testing risks disruption to production traffic if run on a live network, with the potential for use in denial of service attacks, and this is briefly noted in the Security Considerations. Otherwise, there are no obvious transport-related concerns.
