From greg.j.kazz at jpl.nasa.gov Thu Oct 7 00:13:32 2004 From: greg.j.kazz at jpl.nasa.gov (Greg Kazz) Date: Wed, 06 Oct 2004 17:13:32 -0700 Subject: [Sls-slp] CCSDS Fall 04 Link Layer Related WG Agendas Message-ID: <6.0.3.0.2.20041006164041.034661e8@mail.jpl.nasa.gov> All, Here is my 1st draft of the following WG agendas for the Fall 2004 CCSDS Meetings in Toulouse during the week of Nov 15 through Nov 19. Please note that information about meeting location and lodgings in Toulouse is now available on www.ccsds.org. Please also register for the meetings at that web site. This email concerns: CCSDS SLS-SLP WG , CCSDS Link Layer WG, Build-2 Prox-1 WG Please let me know if you have any additional topics you would like to add to these agendas. Draft SLS-SLP WG Agenda: - Pink sheets against the AOS Space Data Link Protocol CCSDS 732.0-P1.1 We took this item up at our last meeting and received approval from CESG to proceed. However, this item was not followed up on i.e., no formal pink sheets were drawn up by the secretariat. I simply want to review these changes to make sure they are still correct (to handle frame accountability for missions reasonably to 150 Mbps e.g., Lunar Recon Orbiter) and cover the changes to TM Sync and Channel Coding, if we ever envision an increase of frame size beyond 16KB. Possible joint Channel Coding and Link Layer topic concerning frame length increase for TM Sync & Channel Coding - Encapsulation Service RED-2 We also took this item up at out last meeting and received approval from CESG to proceed. These changes would make the encapsulation packet header compatible with microprocessors that require 32-bit word compatibility. Draft Link Layer WG Agenda: Concerns itself with the following Link Layer Green Books: - The complete 1st issue of the Draft Proximity-1 Space Link Protocol Green Book will be discussed at this meeting. I will circulate this document to the WG members by email so you can review it before the meeting. - Discuss any comments both internal to the WG as well as received due to the review of the following link layer documents on the CCSDS web site. Current versions of these documents are accessible from http://www.ccsds.org/CCSDS/review/index.html: CCSDS 130.0-G-1.1 Overview of Space Link Protocols Green Book CCSDS 130.2-G-0.1 Overview of Space Data Link Protocols Green Book Proximity-1 Build-2 WG: Work here is currently on hold for now. We have completed all of the revisions on the data link book which resulted in a new blue book and completed the majority of changes to the physical layer but are awaiting the results of an action item on the RF&MOD WG concerning the wording of requirements on data rate accuracies and stabilities. The RF&MOD WG is planning to meet during the week on Oct. 18 in Pasadena and I understand they plan to take up this action at that time. The result of this action item will effect this requirement in the Physical Layer of Proximity-1. thanks, Greg Kazz Chairman CCSDS SLS-SLP WG , CCSDS Link Layer WG, Build-2 Prox-1 WG From greg.j.kazz at jpl.nasa.gov Wed Oct 13 22:58:02 2004 From: greg.j.kazz at jpl.nasa.gov (Greg Kazz) Date: Wed, 13 Oct 2004 15:58:02 -0700 Subject: [Sls-slp] Please Register for the FALL CCSDS Meetings in Toulouse Message-ID: <6.0.3.0.2.20041013155640.02fb4aa0@mail.jpl.nasa.gov> Dear Link Layer WG members, If you are planning to attend the November CCSDS meetings in Toulouse, it is important that you register at: http://public.ccsds.org/sites/calendar/Lists/calendar/Fall2004Meetings/Registration.aspx As soon as possible! thanks, Greg Kazz Chairman Link Layer, SLS-SLP, Prox-1 Build-2 WGs
