Document: draft-ietf-rohc-ipsec-extensions-hcoipsec-05
Reviewer: Elwyn Davies
Review Date: 24 September 2009  (Apologies for slightly late review)

Summary: Almost ready. There should probably be a formal ASN.1 description of the additional fields in the 'Processing' component of the SPD as well as the informal textual description to match RFC 4301. I believe this document
should be specified as updatinbg RFC 4301 (IPsec).

Major issues: None.
Minor issues: Status: Presumably this document should be classified as updating RFC 4301 since it modifies the SPD etc.

SPD additions:
In Section 2.1 some additional fields to be added to the SPD Processing component are described informally. RFC 4301 which has the unmodified version of the Processing component also has a formal ASN.1 description. I think this document needs an updated ASN.1 desciption also.

Further the description talks about adding 'processing info' fields if the 'processing info field is set to PROTECT'. Although this partly reflects the wording in the body of RFC 4301, it is rather confusing when looking at the ASN.1. The wording of para 3 of S2.1 might be better as:
 If the SPD entry is an IPsecEntry (to PROTECT traffic) then the Processing
 item of the IPsecEntry must be extended with the following items:
