Dear SAWG members,

Here is the info for the next SAWG telecon.  We agreed on Thursday, 10 August, starting at 0700 Pacific, which is, I believe, 0800 Mountain, 1500 UK, and 2200 in China.

During the last telecon we concluded that we would just use the CCSDS template to create the Word doc, and not try to use Google Docs since it did not seem to offer any benefits for us and brought some significant complications and limitations.

Ray spent quite a while discussing the revised SOIS layered diagram and we identified a number of issues with it.  The biggest one, at least from my perspective, is that some of the "layers" seemed to include features that belonged in at least 2, and sometimes 4, of the usual ISO protocol layers.  This comes across as both confusing, and also not very well thought out.  Notwithstanding that fact that the ISO BRM does not have any notion of a "messaging layer", which is a common feature of many of today's systems, the other layers, as defined, do still have relevance and value.

Roger presented his updated materials on deployments and these were quite well received.  There is an apparent issue in the SLE services do not appear on the functional deployments.  These are essential services for MOIMS to acquire TT&C services, and they are the most important interface from MOIMS to the rest of CCSDS.

Proposed Agenda for 10 Aug telecon

  *   SOIS Revisions, Ramon
  *   AMS as a messaging layer – Ramon
  *   MOIMS Message and File Service requirements - Roger
