Dear All,

I've added my view onto the end of the rows (I bloomin' hate doing this
via Excel!).

Cheers,

Sam.

Hi Mario, et al,

I've looked over your proposed dispositions.  Thanks for getting them
back promptly.  Several of them are now marked green, accepted.  A few
are marked yellow, discussion still needed.  A few are marked red, and
hese are where I think we have some remaining issues.  For most of these
I have suggested a way forward.  Please take a look and see how many we
can close via email.

If we cannot get it done in that way I will try and find time to meet
with you during the meetings next week.

Best regards, Peter

	Dear Peter, 

	David has gone through your comments and has proposed
dispositions in the attached files. Most of your points have been
accepted. 6 points have been labelled "to be discussed" and have either
a question or a comment associated.

	I would appreciate if you could go through the proposed
dispositions, preferably before the Pasadena meeting, so that we could
earmark some time there to go through any remaining issue face-to-face.
Unfortunately, David will not attend the meeting: nevertheless we could
arrange a splinter SM&C team who could meet with you and David (over a
WebEx) to discuss. For logistic reasons this would be best in the
(early) morning. Could you please identify in your agenda a slot for
this next week? 

	Many thanks 

	__Mario

	Dear Mario, 

	Sorry you are having problems with this.  The document is
attached again here.   It appears that there was some problem with how I
saved the doc, but I had a second copy with all of the comments intact
(see screen shot of the first such comment). 

	Please ask me if anything is unclear. 

	Regards, Peter

	Dear Peter, 

	we have tried to access your comments, but unfortunately the pdf
does not include any comment, despite it shows comment-holders. The
commented YB is instead OK. Could you please resend the pdf to this
distribution list?

	Many thanks, 

	__Mario

P%20Prototype%20Test%20Report-v1-0-ps.doc> 

This document is vastly improved beyond the original and does a credible
job of providing a rather complete binding from the MAL abstract data
types and message formats to a concrete set of data types and SPP
compliant message formats. 

There are, however, still a few loose ends that need to be tied down in
order to ensure interoperability. They are flagged in the document and
listed here: 

1) The "mapping configuration parameter" set (Sec 2.4.2 & Annex B) is a
major element in interoperability, but it is listed as a "managed
parameter" handled by some unspecified out of band agreement. Absent a
way to acquire this key document interoperability is impossible. 

2) There are several issues in the text that must be corrected, such as
stating that the APID Qualifier, an integer field, is to include a "/"
character, the use of Packet Type" does not align with SPP defined
usage, the handling of security / authentication. 

3) The handling of retransmission is left to "lower layers", but many
CCSDS space link protocol deployments do not include such features. Is
reliability, particularly of commanding, to be left to "lower layers",
i.e. "bottom up" or is it a requirement applied by MO operations, top
down? 

4) The test report appears to be quite thorough, but one key element
required for interoperability, that pesky "mapping configuration
parameter" set, is not even mentioned. Also, the details of the test
configuration leave a lot to the imagination and it is not clear how
anyone other than those involved in the test could insert their own MAL
/ SPP component and test it out. See notes on test report for more
details.
