Dear RFM WG,

Based on the number of participants wishing to attend the Interoperability Workshop on Monday, the CCSDS RFM meeting will be moved to Tuesday September 16 morning (8:45 -12:30 CEST).  Inputs are due by EOD Tuesday September 2, and will be posted to the CWE folder as they become available.   The link to the CWE folder is provided below.

Please find attached the preliminary meeting agenda and list of RFM inputs.

Due to a scheduling conflict, I will be participating remotely for this meeting.  Gunther has kindly agreed to co-chair the meeting in case there are difficulties with the remote connection.  I wish everyone safe travels and a successful meeting.

Regards,
Dennis

Subject: [Sls-rfm] Updated 235.1 Pre-RED-1 Generic Session Control
Message-ID: <PH0PR09MB1129417E244E0BC49A26C66479816A@PH0PR09MB11294.namprd09.prod.outlook.com>

Dear SLP, C&S, and RFMOD WGs, and Secretariat:

For your information and review.

Attached please find the updated Generic Session Control Pre-RED-1 book. I will also upload to the SLP WG CWE directory for this meeting.
It contains the updates discussed during both the SLP WG as well as the Joint SLP, C&S, and RFM WG meetings in Hamburg held yesterday.
The changes are limited to Annex E SPDU Type 5 directives.
In summary, we added a new field, ?AOS Frame Length? to the Link Establishment and Control directive (LEC) to accommodate the hybrid use of AOS U-Frames (data frames) and USLP P-Frames (protocol - SPDUs). We slightly modified the Ranging directive to be on a byte boundary and added the" Ranging Code? field and clarified ?No Ranging? to mean ?Ranging Off?.

Secretariat - please use this copy of the 235.1 book for further ending towards producing the final RED-1 version.

best regards,
Greg
Chair SLP WG

Dear All,

As you may remember, during the CCSDS Technical Meeting last week we agreed on 1 action to draw a picture of the different stacks that can be configured via the 235.1 procedure.

Please find attached the Figure we prepared. If you have any comments, please feel free to provide them by the 9th of October.

Regards,

Nicola

Thanks for this nifty diagram, Nicola.

I just have a few comments.


  1.
Technically, RFM is a layer but Sync and Channel Coding as well as the Space Data Link Protocol are sublayers of the data link layer.
  2.
Concerning the note on the bottom right, I propose a rewording:


FROM: Note: With the proper selection of parameters, the bottom layer becomes equivalent to the Proxy-1 Physical Layer so making it a CCSDS Proximity-1 Stack


TO: Note: With the proper selection of parameters, the Physical layer becomes compliant with the Prox-1Physical Layer equivalent to a CCSDS Proximity-1 Stack

regards,
Greg
