This deserves at least a note, which should draw the attention on the fact that some if the Observation Point is located at the interface of an IP router the link header information may not be available.=20 2. Taking into account the observation at the previous point, why do filters defined in section 6.1 for property match operations refer only to the IP header and do not cover also the sub-IP header?=20 3. The Security Consideration section should be explicit about the need for confidentiality of the sampling configuration information and authentication of the entities that configure this information. Even if the methods of configuration are out of the scope of this document, mentioning the basic security expectations for the configuration information will help for selecting the appropriate tools and protocols for this purpose. 4. This being a document that targets Proposed Standard it looks strange that the other PSAMP and IPFIX documents are only mentioned as Informational references. The document reuses terminology and refers to the architecture described in PSAMP-FW and I would expect that at list this be considered essential for the understanding of this document.=20 Editorial 1. It would be useful for the Abstract and/or title to mention that this document is part of the PSAMP family of documents. This helps people searching in the RFC index in the future to identify easier the document and where it belongs.=20 2. The document is using a capitalization convention where all terms defined or mentioned in Section 3 are being written capitalized. This includes quite common and often used terms like Sampling. In order to avoid comments about this capitalization style I suggest to explain this convention in the terminology section.

Thanks for your review. I will address all your comments for in the next version. However, I don't plan to have a new version before the Transport Area directors have reviewed the doc (they asked for an extended deadline)
Please quickly evaluate if you agree with the proposed changes. See inline.
Here are my comments. They are quite a few, it may be because it's a
good document. 

Technical: 

1. Section 3.2.1 - Packet Content. The definition includes in the packet
header the link layer header. This deserves at least a note, which
should draw the attention on the fact that some if the Observation Point
is located at the interface of an IP router the link header information
may not be available.
OLD
   Packet Content 
         
   The Packet Content denotes the union of the packet header (which 
   includes link layer, network layer and other encapsulation headers) 
   and the packet payload. 

NEW

   Packet Content 
         
   The Packet Content denotes the union of the packet header (which 
   includes link layer, network layer and other encapsulation headers) 
   and the packet payload. Note that, depending on the Observation Point,
   the link layer information might not be available.

Moreover, all examples later in the document use
only IP header IE, it would be useful to change or add one example to
show sub-IP header information.

2. Section 8.2 - PSAMP IANA considerations mention the need of a group
of experts to advise on new PSAMP selection methods. This seems a little
overkill to me, as I do not expect this advise to be required too often
in the future. One designated expert to work with IANA would seem to me
sufficient, of curse in doing his work he may consult with a team, but
this needs not be mentioned here.
Note: this was done to be inline with IPFIX information model draft:
   New assignments for IPFIX Information Elements will be administered
   by IANA through Expert Review [RFC2434], i.e. review by one of a
   group of experts designated by an IETF Area Director.
However, I understand your point.

Changes to the section " 8.2 PSAMP Related Considerations "

OLD:
   New assignments for the PSAMP selection method will be administered 
   by IANA, on a First Come First Served basis [RFC2434], subject to 
   Expert Review [RFC2434], i.e. review by one of a group of experts 
   designated by an IETF Operations and Management Area Director.
NEW:
   New assignments for the PSAMP selection method will be administered 
   by IANA, on a First Come First Served basis [RFC2434], subject to 
   Expert Review [RFC2434].
Editorial

1. The document is using a capitalization convention where all terms
defined or mentioned in Section 3 are being written capitalized. This
includes quite common and often used terms like Sample or Flow. In order
to avoid comments about this capitalization style I suggest to explain
this convention in the terminology section.
OLD
 3.    Terminology 
    
   As the IPFIX export protocol is used to export the PSAMP information, 
   the relevant IPFIX terminology from [IPFIX-PROTO] is copied over in 
   this document.  The terminology summary table in section 3.1 gives a 
   quick overview of the relationships between the different IPFIX 
   terms.  The PSAMP terminology defined here is fully consistent with 
   all terms listed in [PSAMP-TECH] and [PSAMP-FMWK] but only 
   definitions that are relevant to the PSAMP protocol appear here.   
   Section 5.4 applies the PSAMP terminology to the IPFIX protocol 
   terminology.

2. Many of the figures get fragmented at print. Now I know that it's
difficult to avoid this in a document with about 20 figures, and doing
.np before each figure would be quite a waste, but I suggest that at
least figure C which is a key architecture diagram be kept on one page.
Ok. I will take care of that.

difficult to avoid this in a document with about 20 figures, and doing

Ok. I will take care of that.

Gold prices continue to rise and have now broken $800 per ounce; a price w did not expect to see till later next year. The increasing demand for gold has intensified exploration operations. Recent findings in Suriname have shown large deposits where more than 50 million ounces have been extracted in that small country. Hemisphere Gold has found gold showing as much as 3.55 ounces/ton on there property which sits right in the middle of the Gold Belt and the largest mines in the region. 5 Key Points To Consider 1. Up over two hundred an ounce since January, gold is on a steady climb daily. 2. The Asian demand for gold has been increasing exponentially in their high growth economy, yet the market is not able to meet the demand. 3. HPGI's use of cutting edge technology has maximized there ability to find gold deposits. Their experienced management team has also been able to accomplish this while keeping costs down during exploration. 4. HPGI is Playing The Gold Belt HPGI's 72,000 Hectare property sits in the middle of two major gold deposits, one of which is already producing. 5. Hemisphere chief geologist has worked with the largest gold companies in Suriname including Newmont and IAMGOLD. These relationships will prove useful during a large gold strike. The decisions you make in the current market need to be wise and precise. HPGI is the type of company that could very well be a great safe haven during the current troubled market. Take the time to review their website and the profiles on Stockguru. It could be the best decision you make this year.

Some more reviews would be appreciated in order to have the first series of IPFIX RFCs

Sorry for late reply. I listed up some my comments, as follows. --- Section 8.2.13-17: If insufficient octets are available for the length specified in the Template, the Information Element MUST NOT be padded. Even if these section elements are variable length type, why do we need to consider the padding? If this description means note about using as fixed length type, I hope additional explanation. --- Section 8.2.15: On the Collector side, I wonder how to recognize frame type of dataLinkFrameSection. In particular, it needs to recognize PPP and EtherFrame. --- Section 8.2.33: This Information Element contains a boolean value which is TRUE if the output from this hash Selector has been configured to be included in the packet report as a packet digest, else FALSE. I understood it as follows. If the value of "hashDigestOutput" is "TRUE", the Selector adds in its "digestHashValue" in exporting packet report. If I didn't misread it, I cannot image the situation on using "FALSE". PSAMP Protocol says that "hashDigestOutput" of each Sector MUST be included in the packet report. psamp-protocol section 6.4.1: If there is more than one digest function then each hash value MUST be included in the same order as they appear in the selection sequence. If there are no digest functions in the selection sequence no element for the digest needs to be sent. --- Section 8.2.27-34: Other configurable Information Elements include the description as a example in a similar way. For example, this Information Element may used to describe the configuration of a Hash based Filtering.

Benoit,
 
The comments resolutions that you suggest seem appropriate to me.
 
It's fine to wait for the transport area experts comments before issuing a revised I-D.
Any news on that front?
Based on IPFIX and PSAMP status http://www1.ietf.org/mail-archive/web/ipfix/current/msg04203.html, [PSAMP-PROTO] is one of the bottleneck.
The next one is [PSAMP-INFO], for which we've got 2 reviews already. A third one is missing.

Regards, Benoit.

Dan,

Thanks for your review. I will address all your comments for in the next version. However, I don't plan to have a new version before the Transport Area directors have reviewed the doc (they asked for an extended deadline)
Please quickly evaluate if you agree with the proposed changes. See inline.
Here are my comments. They are quite a few, it may be because it's a
good document. 

Technical: 

1. Section 3.2.1 - Packet Content. The definition includes in the packet
header the link layer header. This deserves at least a note, which
should draw the attention on the fact that some if the Observation Point
is located at the interface of an IP router the link header information
may not be available.
OLD
   Packet Content 
         
   The Packet Content denotes the union of the packet header (which 
   includes link layer, network layer and other encapsulation headers) 
   and the packet payload. 

NEW

   Packet Content 
         
   The Packet Content denotes the union of the packet header (which 
   includes link layer, network layer and other encapsulation headers) 
   and the packet payload. Note that, depending on the Observation Point,
   the link layer information might not be available.
    
Moreover, all examples later in the document use
only IP header IE, it would be useful to change or add one example to
show sub-IP header information.
Changing the section " 6.4.1 Basic Packet Report "

OLD
   Here is an example of a basic Packet Report, with a 
   SelectionSequenceId value of 9 and ipHeaderPacketSection Information 
   Element of 12 bytes, 0x4500 005B A174 0000 FF11 832E, encoded with a 
   fixed length field.

2. Section 8.2 - PSAMP IANA considerations mention the need of a group
of experts to advise on new PSAMP selection methods. This seems a little
overkill to me, as I do not expect this advise to be required too often
in the future. One designated expert to work with IANA would seem to me
sufficient, of curse in doing his work he may consult with a team, but
this needs not be mentioned here.
Note: this was done to be inline with IPFIX information model draft:
   New assignments for IPFIX Information Elements will be administered
   by IANA through Expert Review [RFC2434], i.e. review by one of a
   group of experts designated by an IETF Area Director.
However, I understand your point.

Changes to the section " 8.2 PSAMP Related Considerations "

OLD:
   New assignments for the PSAMP selection method will be administered 
   by IANA, on a First Come First Served basis [RFC2434], subject to 
   Expert Review [RFC2434], i.e. review by one of a group of experts 
   designated by an IETF Operations and Management Area Director.
NEW:
   New assignments for the PSAMP selection method will be administered 
   by IANA, on a First Come First Served basis [RFC2434], subject to 
   Expert Review [RFC2434].
Editorial

1. The document is using a capitalization convention where all terms
defined or mentioned in Section 3 are being written capitalized. This
includes quite common and often used terms like Sample or Flow. In order
to avoid comments about this capitalization style I suggest to explain
this convention in the terminology section.
OLD
 3.    Terminology 
    
   As the IPFIX export protocol is used to export the PSAMP information, 
   the relevant IPFIX terminology from [IPFIX-PROTO] is copied over in 
   this document.  The terminology summary table in section 3.1 gives a 
   quick overview of the relationships between the different IPFIX 
   terms.  The PSAMP terminology defined here is fully consistent with 
   all terms listed in [PSAMP-TECH] and [PSAMP-FMWK] but only 
   definitions that are relevant to the PSAMP protocol appear here.   
   Section 5.4 applies the PSAMP terminology to the IPFIX protocol 
   terminology.

2. Many of the figures get fragmented at print. Now I know that it's
difficult to avoid this in a document with about 20 figures, and doing
.np before each figure would be quite a waste, but I suggest that at
least figure C which is a key architecture diagram be kept on one page.
Ok. I will take care of that.
