2. CFDP INTEROPERABILITY TESTING WG

Goal: Complete CFDP SFO and Extended Procedures interoperability testing

Working Group Summary Situation:

Working Group Summary progress:• 12 RIDs received during Agency Review (10 INPE, 2 JAXA).

• 1 Approved, 1 Approved with Modification, 3 Rejected, 7 Out of Scope• 7 Out of Scope RIDs were on the base CFDP blue book, not the Pink

Sheets• Agency RID Review Dispositioning complete,

• No need for second round of Agency Review• Document approved for publication as 727-B-04 per Secretariat

• The need for a corrigendum to 727-B-04 has been identified to clarify an issue raised in the Pink Sheet review

status: OK CAUTION PROBLEM

comment: Agency Review RIDs dispositioned.

2. CFDP INTEROPERABILITY TESTING WG

Document Summary:• CFDP Green Books (720.1-G-3, 720.2-G-3) updates in CESG review• Forthcoming Books (in Secretariat’s editing queue)

• Three interoperability testing notebooks (common interoperability tests for core, extended, SFO – 720.4-Y-1, 720,5-Y-1, 720.6-Y-1)

• Interoperability Testing Final Report (720.3-G-1)• Working group will be dissolved when Green books are updated and

approved for publication

CFDP Segment Metadata BOF• Meeting of working group endorsed formation of CFDP Segment Metadata

BOF• Optional capability to attach metadata to each CFDP file segment• Purpose is to clarify and enhance processing of record-structured files

3. CISLUNAR SPACE INTERNETWORKING WG (CSIWG)

Goal: Design a communications architecture for cislunar and possible Mars in-situ environments; update existing CCSDS standards to reflect recent advances in telecommunications.

Working Group Status: Active _X_ Idle ____

Working Group Summary Situation:

Working Group Summary progress:• Green Book in CESG Review, closes 12 February 2007.

• WG agreed that long-outstanding RID concerning SCPS-NP’s inability to carry IPSec AH information did not warrant document change. WG concludes that IPSec AH is largely deprecated in favor of IPSec ESP with a null encryption algorithm, which SCPS-NP can carry.

• The WG is currently developing first draft Magenta Book, Part 1.

Problems and Issues:• The working group is running 6-9 months behind its charter due to WG personnel

responsibilities to Constellation project. WG has split its current Magenta book into multiple parts. Depending on the rate of progress before the next CCSDS meeting, this may need to be addressed by a charter modification.

• Need close coordination between CSI WG and the proposed Mars WG to ensure appropriate evolution toward Mars In-Situ protocol selection and routing approaches.

4. ASYNCHROUS MESSAGING SERVICE WG

Goal: Resolve relationship between AMS and MOIMS SM&C, SOIS App. Supt. Svces

Working Group Status: Active

Working Group Summary Situation:

Working Group Summary progress:• RIDs from CESG review resolved – Service classes seen as the appropriate way of dealing

with issues raised

• 2nd Implementation:

• NASA/GSFC will develop prototype in FY07. Options:

• Java implementation of entire AMS protocol suite

• C implementation, possibly phased through multiple service classes

• CNES may develop prototype in Java for high-altitude balloon operations.

• NASA/MSFC may develop prototype in C# for Windows.

Problems and Issues:

• None

status: OK CAUTION PROBLEM

4. ASYNCHROUS MESSAGING SERVICE WG (Continued)

Future Plan:

• Complete agency review of initial AMS Red Book, resolve RIDs (nominally complete by end of July 2007)

• GSFC Java implementation progresses during RID resolution, both JPL and GSFC implementations modified as necessary to reflect RID resolution

• Interoperability testing begins September 2007, interim report in Darmstadt, completion by end of 2007

• Jan-Feb 2008: Draft Interoperability Testing report and revise Red Book if necessary to reflect issues identified by interoperability testing

• Estimate CESG/Agency Review in February-April 2008

• Green Book preparation in February-April (during Red book review)

• RID Resolution, Final Blue Book Text Preparation May-June, 2008

• Submit to CMC for Blue Book publication, July 2008, Green Book review

• Green Book publication end of September 2008

• Dissolution after Fall 2008 meetings

Charter update in progress to reflect revised schedule/resources

5. IP over CCSDS Links WG

Goals:

• Progress white book to Red book status.

• WG Status: Active X Idle ____

status: OK CAUTION PROBLEM

comment: Agency ReviewRID Resolution

SIS AREA REPORT

Working Group Summary progress:• Agency Review RID resolution against Red-1 Draft Magenta book

• RIDs editorial in nature, all accepted• WG discussion provided slight organizational changes to help

facilitate the user’s understanding of the summary information presented in the book

• These changes will be made by the author before submission to the CCSDS secretariat

Problems and Issues:As discussed in joint CESG/CMC meeting: inadequate agency review

performed. Action to secretariat to extend agency review until 1 March 2007.

6. Mars Interoperability Birds of a Feather

Goals:

• Form a Mars Interoperability Working Group.

• WG Status: Active X Idle ____

status: OK CAUTION PROBLEM

comment: Draft Charter Complete

SIS AREA REPORT

BOF Summary progress:• Draft Charter complete and submitted for approval• Expected products: PICS proforma for Prox-1, Magenta Book specifying

near-term Mars Profile, Green Book describing evolution of Mars networking capabilities

Problems and Issues:• Coordination needed with SLS, Cislunar WG

24 January 2007 14

D. Cross Area Issues

• AMS/SOIS, AMS/SM&C – Cross-area meetings held to discuss issues, initial Service Class definitions created

• Mars WG is defining PICS Pro Forma and selecting options in Proximity 1 Protocol, needs to coordinate with SLS

• Cislunar/High-Rate Uplink coordination required on an ongoing basis. Have requested more specific HRU requirements from Cislunar chair.

• Intra-Area Issue: SIS Plenary was on Saturday, only NASA participation, not all WG Chairs present
