I understand this should expand to "Must Be Zero" and it MUST be set to zero by senders and MUST be ignored by receivers. It makes sense to add this to the terminology section or before first use. >> GIM>> MBZ is used only in figures that reflect updates to formats defined in RFC 5357. None of fields defined in RFC 5357 referenced in this proposal and their identification in the figures is the same as in RFC 5357. I think it may be confusing to those familiar with RFC 5357 to see "Must Be Zero" instead of MBZ in figures. >> >> * Please cite as references RFC2474 for the DSCP field and RFC3168 for ECN. >> GIM>> Thank you, will add references and send diff for review. >> >> * Section 2.2.1: >> >> "the first six bits of the Differentiated Service field" >> >> Not sure if this "first" qualification is required as RFC2474 defines the DSCP field to be *exactly* 6 bits long.

Is this correct?

RFC 6038 states that in order to support Symmetrical Size and/or Reflects Octets modes Session-Sender must append at least 27 octet-long Packet Padding. Because the DSCP and ECM Monitoring extension requires Session-Reflector to copy additional octet, the minimal size of Packet Padding to support RFC 6038 must be 28 octets. >> >> Editorial >> ========= >> >> * Section 2.2.1 >> >> s/MUST extracts/MUST extract/ >> GIM>> Done. >> >> Thanks >> Suresh >> >> > > > _______________________________________________ > Gen-art mailing list > Gen-art@ietf.org > https://www.ietf.org/mailman/listinfo/gen-art
