Concept Book Review
• Updates• Figure 3-1: (1st) to be revised to show only functions at
an abstract high level• Figure 3-2: Terrestrial WAN Node moves to be inside the
Provider Domain• Figure 3-2: Add a connection between Control Node +
ESLT• Figure 3-3: All block definitions should be stereotyped• SSI Diagrams – Need same treatment as Fig 3-1, 3-2 (ie
abstract functions vs node definitions)• Open question: Does enterprise model need to show 3-
way configurations (e.g, NASA/DSN uplink, ESA/ESTRACK downlink)?

Functional Resources Review(Joint Mtg w/CSA, CSTS WGs)
• Agreed that FRs are on the right track• Mapping from CSA (Cross Support Architecture) to
FR seems quite feasible• An annex and/or reference to the FR techincal note is to
be added to the CSA• Question of granularity still to be sorted out (functional
resources vs. functional group defintions – later more useful for the CSA)
• Question of reference model refresh• (Subsequent discussion is that this is on hold as
resources are not available to do examine the existing SLE Reference Model)
• ESLT is where DDOR correlator “lives”

CSSM Information Entities (1/3) • Extensibility considerations now more focused on per information
entity basis• Extensibility concerns discussed noted on following slides
![Page 9: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/9.jpg)
CSSM Information Entities (2/3)
• Extensibility Considerations for Service Catalog• New Services Definitions• Additional service capabilities• Agency Specific Offerings
• Extensibility Consideration for Service Agreement• New Service Definitions, e.g. ranging• Additional service capabilities• Agency Specific Offering• Separation of (existing) operational (management service)
constraints from functional resource constraints• Lifecycle phase refinement, e.g., compatibility testing/validation • Financial Information/Data• Functional Resources
- Examples- RF/Modulation Schemes- Terrestrial Data Transfer protocol configuration
![Page 10: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/10.jpg)
CSSM Information Entities (3/3)
• Extensibility Considerations for Configuration Profile• New Services Definitions• Additional service capabilities• Agency Specific Offerings• Functional Resources• Examples• RF/Modulation Schemes• Terrestrial Data Transfer protocol configuration
• Extensibility Considerations for Service Package• Temporal constraints, e.g. Rules for scheduling a series of service packages
![Page 11: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/11.jpg)
Schedule of Services WB Review
• Use Case definitions Generally Okay
• Activity Type This becomes service(s), and become part of schedule item
• Antenna ID becomes AntennaRef
• Frequency Band Added to the Service Type data class- Action to M. Gnat; C. Circolan: provide some frequency band parameter
definitions (apparently there are not standard frequency band definitions)
![Page 12: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/12.jpg)
Schedule of Service Prototyping/Test Plan
• Prototyping Activity So Far:• NASA Rep (C. Audain) has produced examples schedules for SN
and one NOAA• DLR Rep (M. Gnat) has received schedules
- Examined via XML SPY- Conclusion: Makes sense, okay so far
• Some Findings:• Set up time: NASA NEN appears to selectively include set-up/tear-
down times; ie not used routinely• Agreed to make optional as it appear that some networks do not use
this/need it.• Agreed to allow additional parameters for Service Type class (bi-
lateral) (in addition to those for Scheduled Activity class)• Agreed to add Orbit number to Scheduled Activity class
• Test Plan Review:• Agreed to remove test case 3• Agreed to add round-trip test case• Agreed that Test case 4 can be done a rather lightly -- no need to set
up the implied infrastructure

Road Map
A preliminary road map for revised concept was produced; subject tofurther revision, refinement, updates based on project definitions, subsequent extensibility analysis, etc.
![Page 14: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/14.jpg)
Extensibility Model, Configuration Profile
![Page 15: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/15.jpg)
Ext. Model, Configuration Profile -- Notes
• Framework meta data• Common across all information entity definitions • Allows for referential framework much like current Blue-1
• Functional resources • Forms the (abstract) basis for identifying the functions that are
being managed
• Functional group• Collection of functional resources with well defined affinities
sufficient that the grouped functional resources can be treated as unit
• Services • Identifies the cross support services in terms of functional groups
• “Wiring”• Composition of the configuration profile information entity with
respect to the above
![Page 16: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/16.jpg)
REST
• May potentially replace or allow for a “slim”/”lightweight” service definition if and when agencies are ready for management services
• See A. Crowson’s presentation darft analysis -- RESTful CSSM
![Page 17: CSSM Meeting Summary Spring 2013 Meetings 15 – 18 April E. Barkley Chair (NASA/JPL) C. Haddow Co-Chair (ESA/ESOC) Bordeaux, France](https://reader035.vdocuments.us/reader035/viewer/2022062717/56649e4c5503460f94b41401/html5/thumbnails/17.jpg)
Situational Awareness
Inputs, comments were solicited from WG members in attendance re agency development related to service management…
• ESA• Desire to have something fairly quickly• Recognize that BLUE-1 is not really it
• DLR• Similar concerns to ESA
• UKSA• No plans to implement SM currently• May be some private tracking operations that could consider using
• JAXA• Looking at Blue-1 implementation
• NASA• SN ground sustainment task is taking a conceptually similar approach to
Blue-1 but is not really Blue-1• TTC networks integration project has been initiated is looking to adopt
post-BLUE-1 SM standards
