Dear SLS-SLPers and Bob Durst,

We have been doing work with projects at JPL such as the ELECTRA 
transceiver project (providing the multi-mission Mars transceiver) and 
others that require 32-bit compatiblity in the data they receive and 
transmit. Words have to allign on 32-bit boundaries otherwise the user has 
to provide fill.

The current version of the CCSDS encapsulation packet header allows for two 
options that are not 32-bit compatible. We are proposing a change to the 
header in the attachment, so that the header would be 32-bit compatible.

This change effects 3 CCSDS recommendations: 2 in the SLS area and one in 
the SIS area (Space Packet).

Please let me know your thoughts on this proposal. My goal is to have an 
on-line BOF discussion and bring the results of the discussion to the 
Spring meeting in Montreal at the SLS area meetings.

thanks,

Greg

Greg: this comment is completely off the top of my head, but if we are 
thinking of screwing around with the CCSDS Encapsulation header then is 
there any mileage to be gained by making it compatible with the new  "Ultra 
Lightweight Encapsulation (ULE) for transmission of IP datagrams over 
MPEG-2/DVB networks" --

http://www.ietf.org/internet-drafts/draft-ietf-ipdvb-ule-00.txt

What I'm thinking here is that if space Network layers had a common 
encapsulation interface that provides a standard convergence service for a 
variety of underlying space link services, we might gain a lot of future 
flexibility. IP traffic could then run over CCSDS links, or DVB links, with 
a common interface shim.

Could someone take a look at this early-on just to gauge the feasibility? 
It seems to me that Gorry Fairhurst's work is not yet cast in stone - so is 
there a way for us to get our oar in his water so that his ULE and our 
CCSDS Encapsulation protocol both converge within his Internet Draft - thus 
increasing the credibility of IP-over-CCSDS?

Ed: agreed - but my point is that you should be saying that to Gorry 
Fairhurst, not to me. Do you think that we are the only people in the world 
who would like to see efficient use of space links? The choice to use IP or 
not will depend on mission requirements, but maybe there are some folks out 
there in DVB-S land who would like to use IP but who would equally well 
like to see a "Mega-lite" encapsulation mechanism. We ought to at least 
explore the possibility before we go off and build our own.

By the way, does anyone know if the commercial guys like Avtec, who build 
CCSDS link equipment, have been invited to join this proposed BOF? Before 
we bugger around with the space link protocols, we should be consulting the 
people who have invested serious money in the current infrastucture.

In my restructured books, the Encapsulation Packet is only defined in 
a recommendation called "Encapsulation Service" so that it can be used 
over any Space Data Link Protocol.

It was published as a CCSDS Red Book (attached to this message) in 
April 2002, but it has not reached the status of Blue Book yet (I 
don't remember why).

If we are to change the format of the Encapsulation Packet, this is 
the book that we should modify.

Best regards,
Takahiro Yamada.

Message-ID: <4.2.2.20040326120431.01e0bec8@mail1.jpl.nasa.gov>

All,

As Takahiro pointed out, the change needs to be against the Encapsulation 
Service Red book of April 2002, in order to change the header of the 
encapsulation packet.

Attached are the proposed changes.
Please let me know if you have any comments.
