[Sls-slp] Re: Encapsulation PIDs for DTN, LTP, etc

[Scott, Keith L.]

Greg,

I'll bring this up with the WG on Wed morning; I hope to be able to resolve via email but a mini-tem is ok too. Obviously we can live with just ltp, but then we take a bit of an overhead hit when reliable prox-1 is available. On the other hand we do get something out of ltp even over reliable links.

Keith,

There are 3 Primary PIDs currently available and 16 extended PIDs available. See Encap Packet Header.
Gian Paolo suggests that we have a mini-TIM between our WGs to discuss this.
If we can work it out over email, that’s good too.

Greg,

We've been thinking about the following:

1) DTN directly over Encap (e.g. When used over prox-1 reliable packet service.)

2) DTN over LTP over encap over (tc/tm or aos)

Thus, would it make sense to have encap pids for each (ltp and 'direct DTN') (how many ids are available)?

Scott - I'm assuming that ltp would use the Client Service ID to identify dtn vs. Other ltp users.

Keith et al,

SLS-SLP WG would like to know if the DTN WG needs to define Encapsulation Protocol IDs (PIDs) for LTP blocks, or DTN Bundles, or something else?
The actual value of these PIDs would go into the Space Link Identifiers Blue Book.
SLS-SLP WG is advancing the Space Link Identifiers Blue Book to a new version as a result of our meeting today.

Please let me know if you want to comment on this issue.

Thanks,

Greg
