Jeff Schiller (the Security Area Director) has indicated that: RFC-1829 is the product of the IPSEC working group. It is for the working group to decide whether or not to advance it. I will happi ly act upon a recommendation of the working group as communicated to me by the chair. As interoperability has been demonstrated between 2 or more implementations, I ask that this document be immediately forwarded (within a few days) to the Area Director for advancement to Draft Standard. I'm afraid I disagree; this document is not ready for advancement. First, it's the wrong document. Given the new structure (i.e., as described in draft-ietf-ipsec-new-esp-00.txt), there's far too much in your draft. The CAST-128 draft (draft-ietf-ipsec-esp-cast-128-cbc-00.txt) or RC5-CBC draft (draft-ietf-ipsec-esp-rc5-cbc-00.txt) are much better models for what's needed. (Bill, I realize you feel differently. I don't like documents that overspecify stuff -- changes to the base document's headers would require changes to your document as well, quite unnecessarily.) Second, given the new structure -- with authentication folded in with ESP -- I don't know of any implementations. I suppose one could say that the DES-CBC part is ready, but it's a bit hard to assess without the framework.
