Suresh Krishnan has entered the following ballot position for draft-ietf-dots-data-channel-28: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-dots-data-channel/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- * Section 4.3 The processing requirements for the tcp flags bitmask is not at all clear. Specifically how should an implementation use the values in the flags, operator and the bitmask fields in the tcp subtree to figure out if a given packet matches. An example here could be very helpful. "Bitmask values can be encoded as a 1- or 2-byte bitmask." How? The bitmask field is a uint16. How would a client indicate a 1 byte bitmask? [Also note that there are *nine* flags defined for TCP including the experimental NS bit that occurs as bit 7 of Octet 12 and a 1 byte bitmask will not catch them all] ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- How does the flags field in the ipv4 match subtree interact with the bits in the fragment side? I can easily see that someone can make a mistake due to this redundancy and come up with something that is not coherent. e.g. bit "more" under flags is set and bit "lf" under fragment-> type is also set .
