Dear All, we've worked on addressing the comments received from our AD and much appreciate your feedback, questions, and suggestion. Some questions raised by Alvaro in AD's review are yet to be closed <https://mailarchive.ietf.org/arch/msg/bier/S2Bp2YDgVEmyLaGhX6HxxVNnuMs/>: 1. Track: Experimental, Informational, or Standard? - RFC 8321 is Experimental. Alvaro has pointed that “given that rfc8321 is not mature enough, what should be the Status of this document: Experimental or Informational?” 2. Relationship to draft-ietf-bier-oam-requirements: - Added reference is the right step but not enough - If WG is resolute to publish draft-ietf-bier-oam-requirements, it should progress at least in-step with this draft - Using the OAM field for Marking Method - Could there be other interpretations and use of the OAM field of BIER header or only for the Alt.Marking method? - If the interpretation of the OAM field is only as defined in this draft, then it must be marked as update of RFC 8296. - In any case, IANA Considerations section doesn’t make sense - remove 3. Naming flags: - L(oss)/D(elay) vs. S(ingle)/D(ouble) A new text has been added to clarify an operational aspect of using the Alternate Marking method in a BIER domain: NEW TEXT: Selection of a time interval to switch the marking of a batch of packets should be based on the service requirements. In the course of the regular operation, reports, including performance metrics like packet loss ratio, packet delay, and inter-packet delay variation, are logged every 15 minutes. Thus, it is reasonable to maintain the duration of the measurement interval at 5 minutes with 100 measurements per each interval. To support these measurements, marking of the packet batch is switched every 3 seconds. In case when performance metrics are required in near-real-time, the duration interval of a single batch of identically marked packets will be in the range of tens of milliseconds. The authors are looking forward to working on progressing this specification.
