Just one item to correct here, the assertion that "they are not planning a CSTS service for TM/TC/AOS frames". There is a planned new CSTS service called Forward Frame (FF-CSTS). It is to parallel the existing SLE R-AF and R-CF, and it has the following features:
1. Accepts AOS, TC frames in native form (and USLP when it is published) (F-CLTU only accepts encoded TC frames)
2. Accepts inputs from multiple sources (either users or other services like DTN BP or CFDP file agent)
3. Merges these inputs into a single frame stream
4. Applies encoding (F-CLTU requires that BCH coding, only, be applied by the user)
5. Inserts idle frames if needed to maintain link synchrony
If you followed the logic (and the notes) you will see that this service is essential for any future DTN or CFDP file service deployments. I think it would be worthwhile having the Sec WG have a discussion with the CSS area, CSTS WG on this topic. Likewise I think having the SecWG take a look at the other new planned CSTS service, Service Control (SC-CSTS), would also be of value.

thanks a lot for the two mails you sent me - and sorry for not beeing more
presice in the one I sent on Wednesday.
You`re absolutely right - and this was also what I remembered from the Rome
meetings: my action is to review section 6.3.
Until now, in this section we only talk about the influence of applying
security (either SDLS or higher layer security) on SLE services. I was
wandering if there would also be an influence on CSTS services, so I proposed
to write a chapter about this as well.
But after what I learned from the CSTS books and from my colleague (being the
fact that they are not planning a CSTS service for TM/TC/AOS frames) I`m not
sure any more if talking about CSTS in chapter 6.3 makes sense at all.
What do you think?
