CONCLUSIONS
OMG liaison Panel 3 expresses
its interest for a cooperation with the OMG Task
Force. Panel 3 is willing to contribute to a
liaison between CCSDS and OMG, within the
framework defined by MC. Before any commitment
the method of a cooperation has to be defined (at
Agency level, or at CCSDS level), and the
corresponding workload has to assessed.

15
CONCLUSIONS
- Good progress in SLE recommendations -
New Red books for Transfer Services in July
2000 - New RED 2 for SLE Service management
book in December 2000 - Excellent return from
INTEGRAL Project SLE API implementation - Need
more RF expertise in WG1 for S/C RF
Characteristic book - Request for Resource in
order to develop SLE API ( over TCP/IP)
recommendation based on INTEGRAL documents - No
start of New Work Items

CCSDS P3 Workshop 13 - 16 June 2000

• Candidate Future Work Items
• Service and Management Interface for file
  exchange May include specification of a
  suitable API May provide a uniform interface
  for FTP and CFDP based file transfers May
  include access to meta data, catalogue and the
  like may be suitable for handling various
  kind of files (offline telemetry, radiometric
  data, trajectory predictions, command files,
  )
• Telemetry Catalogue Common need /
  requirement Supported by most legacy systems
  Lack of such catalogue perceived as SLE
  deficiency Suggested action All agency to
  provide a description of the catalogue content
  and catalogue based telemetry access
  capabilities
• Time Correlation Common need (agency
  specific solutions in place) Is it justified
  to still invest into a TM based time correlation
  service? What will be the impact of the new
  method currently being discussed in P1A?

CCSDS P3 Workshop 13 - 16 June 2000

• Candidate Future Work Items
• Radiometric Services Availability of such
  services (Range and Doppler measurements) is a
  highly important cross-support issue both in
  terms of access to the measurement results
  (transfer service) scheduling of range
  measurements (service management)
• CCSDS - OMG Liaison to be discussed

Fall 99 Panel 3 Organization
The Working Group structure was updated in
Darmstadt, Oct 1999
WG 1 responsible for WP 210 (TCM), WP 220 (
SLE Services Models and Concepts) and WP340 (SLE
Management). This group maintains the 1. TCM
- existing Green Book No change needed 2.
Cross support Concept - existing Green Book
revision needed 3. SLE Reference Model
documents - existing Blue Book revision
needed 4. SLE Service Management Specification
- existing RED in Fall 1999 5. SLE Managed
Object Formal Specifications - existing
draft 6. SLE Service Management Information
File Specifications 6.1 SLE SM Spacecraft
Characteristics 6.2 SLE SM Data Channel
Tree 7. SLE SM Authentication and Access
Control 8. SLE SM Implementation Mapping
Rules Lead of WG1 Fred BROSI (NASA/GSFC)

Fall 99 Panel 3 Organization

• WG2 responsible for the WP310 ( SLE
  Return Services Specifications). This group
  develops the detailed specifications for the SLE
  Return Services, according to SLE Reference Model
  and Service Management Specification documents,
  with the following priorities
• 1. Return All Frames ( RAF) - existing RB
  (July 98), new RB-2 in fall 99
• 2. Return Virtual Channel Frame (RCF) -
  existing RB (July 98), new RB-2 in fall 99
• 3. Return Master/virtual Channel (ROCF) -
  existing WB (Oct 98)
• 4. Return Master/virtual Channel FSH (RFSH)
  - existing WB (Oct 98)
• 5. Return Space Packet (RSP) -existing WB
  (July 98)
• Lead of WG2 Martin Pilgram (DLR)

WG3 responsible for the WP320 (Forward Tele
command Services Specifications). This group
develops detailed specifications for the SLE
Forward Tele command Services according to SLE
Reference Model and Service Management documents,
with the following priorities 1. CLTU - Red
version reviewed by Agencies April 98, new Red 2
fall 99 2. Tele command frame - existing WB
(April 98) 3. Forward Space Packet - new RB2
(July 99) 4. Tele command VCA - existing WB
(July 98) Lead of WG3 Martin
Pilgram DLR)
21
Fall 99 Panel 3 Organization

• WG 5 responsible for WP 510
  (Telecommunication services for SLE services
  especially for WP 511 ( SLE API) and WP 512 (
  SLE Services security)).
• This group will
• Specify a recommended application programming
  interface (API) for applications to interface to
  the SLE service element
• Select appropriate safeguarding techniques for
  user authentication and data object protection to
  support implementation of the SLE services
• Select a suite of available standard
  communication and related services and protocols
  to support implementation of the SLE services
• It initially addresses SLE-API and SLE security
  framework. Later it will expand to include
  additional other communications aspects (e.g.,
  transport, middleware, directory services)
• Lead of WG5 Michael Stoloff
  (NASA/JPL)

Related SM Books

• ACA
• Technically correct, but needs updating to
  reflect latest SLE API
• Descriptions need refinement
• RF Characteristics
• Need to address dynamic vs. static attrib
• Compare INTEGRAL attrib
• Incorporate VEGA implementation comments
• Write front matter (according to ACA)
• Expert review

24
Related Documents (Part 2)

• SLE Executive Summary Green Book
• 10-20 page overview of SLE Concepts Document
  Suite
• Cross Support Green Book
• Combine existing concept doc with
• Existing SM Raw Material (concepts/scenarios)
• Green material removed from SM
• GDMO
• Will probably include UML diagrams
• 35 Mos currently completed pertaining to CLTU
  service
• Remaining Mos to be drafted
• MO Registration (current Annex D) to be included

25
Related Documents (Part 3)

• Technology Dependent Implementation of BIND
  Operation
• WG1 to develop MO description
• Propose to include in WG2/3 SLE API
• Mapping Rules (Simple File Exchange)
• To be converted into CCSDS format
• In process, will consider XML (and PVL, SOAP,
  whatever)

26
Plan

• Produce SM Red-2 by December 2000
• 2 intermediate meetings
• Early September
• Late October
