[Sls-slp] Call for Use Cases of Space Packet Protocol

[Greenberg, Edward (312B)]

I'm sure it can but everyone has their own unidentified secondary header.

Ed, I think of the Space Packet as being the thing that the old Constellation project called a Data Exchange Message (DEM).  I think it performs the same function in the stack, and I suspect that it could easily carry all the same metadata that the DEM was supposed to carry.

There seems to be lots of new Use Cases for Space Packets then were considered in the original specification. For example:

  *   ESA has PUS
  *   Space Station has its own secondary header
  *   Orion is looking for a secondary header
Originally the Space Packet was an envelope for data transferred over single link (includes tunneling), now the packet is being looked at for network data transfer, local onboard data transfer (including measurement broadcasting).
It is possible that the role of the packet might change with the use of DTN bundles.
Just to take the broadest view: We currently have two forms of packets, should there be more or should even these be examined to determine if they should be blended  into a new packet design.
Can we get each of you to send in your present and possibly desired Use Cases for our beloved Space Packet so that we could determine its future.
