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" --
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?
