Draft: draft-ietf-crisp-iris-xpc-04.txt Reviewer: Black_David@emc.com Review Date: Thursday 8/24/2006 3:27 PM CST IETF LC Date: 8/28/2006 Summary: This draft is on the right track but has open issues, described in the review. I found one open issue - Section 14's discussion of the use of SASL is incomplete, as it does not satisfy the requirements stated in Section 4 of RFC 4422. See Section 4 of RFC 4422. I also found a few minor concerns/nits: Sections 5 and 6 ought to contain ASCII diagrams of the bit fields in the Block Header and Chunk Descriptor. The discussion of chunk ordering in Section 6 on p.9 combines restrictions on which chunk types may co-exist in a single block with requirements on ordering of those types within a block. The combined discussion is somewhat confusing - it would be clearer if these two topics were separated - specify what is allowed within a single block, then specify ordering requirements for what is allowed. Section 9 should state how the client and server determine whether TLS is to be used. Since well-known ports are registered for both XPC and XPCS, this appears to be determined by client selection of which server port to use.
