CCSDS Toulouse
November 2004

2. Cislunar Goals
Create a top-level architecture and operations concept for communicating effectively over the whole range of cislunar distances.
Review current and emerging CCSDS standards and recommend any updates required to keep them current.
Examine the spectrum of new Internet development activities that are proceeding, and identify where they may be applicable to cislunar
Recommend standards for cislunar communications.
Define architecture that handles:
Voice/video (realtime and non-realtime)
Data (realtime and non-realtime)
Between Earth and Moon (RTT ~2.5s)
Extensible to Mars (RTT ~ minutes)

3. Cislunar Activities Green book describing Interface with C3I activity
Architecture
Operations Concept
Interface with C3I activity
Paper describing candidate protocols
Review of applicable CCSDS Protocols
SCPS-TP Updates

4. Starting from…
Treat CCSDS channel access services as interfaces to IP

5. And recognizing ongoing work in the IETF…
The Stream Control Transmission Protocol SCTP.
The Datagram Congestion Control Protocol (DCCP).
Voice Over IP (VOIP).
Disruption Tolerant Networking (DTN).
LEMONADE enhancements to Internet to support diverse service environments.
Internet over Digital Broadcast Video Networks.

6. IP-Based Communications Architecture
Single packet-switched network carrying:
Voice (over IP)
data
HDTV
Quality of Service
Protect life-critical and mission-critical data from congestion
QoS options (not mutually exclusive)
Manually set up class-based queueing classes
Integrated Services
Differentiated Services
Standard IP TOS

7. “Draft Green Book”
More a compendium of tools with some rationale for why they’re needed
Needs
Architecture
Use cases / scenarios to beat the architecture against

8. Review current and emerging CCSDS standards
A number of vendors are selling SCPS-TP-based Performance Enhancing Proxies (PEPs)
SIS-SCPS-INTEREST mailing list started to get vendor inputs
All the major SCPS vendors that I know of are on the list
Active discussion of SCPS-TP
Clarifications to improve interoperability
Possible extensions to address specific needs
