Peter, Richard, and Tom,

Attached is the CCSDS BP Document modified per the conditions from the CESG Poll, with the following exceptions:

Richard:
You had noted a couple of grammatical anomalies in the paragraph preceding figure 2-1; a subtle difference between the word document and the pdf that went out for review removed one of these already, so I reworded things slightly to fix the second.  The change amounts to:

FROM:
Figure 2-1 shows an example configuration in which the Bundle Protocol and a convergence layer (CL A) running above a transport protocol (intended to be interpreted in the context of the Internet stack) on the left, and running directly over a Data Link Layer on the right.

TO:
Figure 2‑1 shows an example configuration with the Bundle Protocol and a convergence layer adaptor running above a transport protocol (intended to be interpreted in the context of the Internet stack) on the left, and running directly over a Data Link Layer on the right.

I think this addresses the intent of your condition, but please confirm.

Peter:
In the note at the end of section 1.4, I reflected the agreed-to changes in the first sentence throughout the note.  The updated text reads:

A CLA enables the BPA to interact with an underlying data transport mechanism such as a link or network to send and receive bundles.  The manner in which a CLA sends and receives bundles is an implementation matter and is unique to the underlying transport mechanism.  Therefore the BPA may utilize CLAs from a number of different underlying transport mechanisms subject to the routing of traffic.


Can you confirm that these do in fact address your conditions and, if so, I think it’s over to the secretariat to schedule the CMC poll.


V/r,

Hi Keith,

I think we are close.  Please take a look at the notes in the attached.

Thanks, Peter

Peter and Richard,

I think the attached spreadsheet captures SEA’s and SOIS’ comments on the CCSS Bundle Protocol Specification.

I have included proposed dispositions/corrections in column F.  When we come to closure on these I’ll ask if you can let the CESG know so we can complete this.

V/r,

—keith
