Hello, I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see ​ http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-i2rs-traceability-06.txt Reviewer: Mach Chen Review Date: 2016/1/18 IETF LC End Date: Intended Status: Standard Track Summary: I have some minor concerns about this document that I think should be resolved before publication. Comments: The document is well written and easy to read. Minor Issues: 1. The draft Intended status shows: Standards Track, but the Intended RFC status in the datatracker is "Informational". I think the latter is true, right? If so, please update it accordingly. 2. Section 5.2 Client Address: This is the network address of the Client that connected to the Agent. For example, this may be an IPv4 or IPv6 address. [Note: will I2RS support interactions that have no network address? If so this field will need to be updated.] IMHO, the Note should be deleted for a to-be-published document. The IPv4 and IPv6 are just examples, the description here does not exclude other possibilities. 3. Section 5.2 Requested Operation Data: This field comprises the data passed to the Agent to complete the desired operation. For example, if the operation is a route add operation, the Operation Data would include the route prefix, prefix length, and next hop information to be inserted as well as the specific routing table to which the route will be added. The operation data can also include interface information. Although the last sentence above is right, why do we need to emphasize the "interface information" here? If there is no special intention, I'd suggest to remove it. 3. Section 5.2 Transaction ID: The Transaction Identity is an opaque string that represents this particular operation is part of a long-running I2RS transaction that can consist of multiple... Here you specify that an Transaction ID is an opaque string, are there other possibilities (e.g., uint) ? Since this is just an information model, how the data type should be is specific to the data model, I'd suggest to remove the data type limitation from this document. Best regards, Mach
