1 Space Communications Cross Support Architecture WG: Charter and Work Plan April, 2009 Colorado Springs, CO, USA Takahiro Yamada, JAXA/ISAS

2 Introduction  This presentation shows:  the charter of the Space Communications Cross Support Architecture WG,  the current status of each item defined in the charter, and  goals of this meeting.

3 Goals Defined in the Charter (1/2)  Development of a Space Communications Cross Support Architecture recommended practice that:  Identifies the cross support forward and return services,  Identifies the management functions, and  Offers various views to fully describe the architecture.  Development of a recommended standard for service catalogs that:  Defines template(s) of catalog contents, including a formal schema,  Offers two or more examples of an instantiated service catalog, and  Identifies mechanism(s) for catalog maintenance.

4 Goals Defined in the Charter (2/2)  Development of a recommended standard for service agreements that:  Defines template(s) of service agreement contents, including a formal schema,  Offers two or more examples of an instantiated service agreement, and  Identifies mechanism(s) for service agreement maintenance.

5 Deliverables Defined in the Charter NameCategorySchedule Space Communication Cross Support Architecture Recommended Best Practice (Magenta Book) R1 - October 2009 B1 - May 2010 Cross Support Service Catalog Recommended Standard (Blue Book) R1 - October 2009 B1 - May 2010 Cross Support Service Agreement Recommended Standard (Blue Book) R1 - October 2009 B1 - May 2010 Technical note identifying modifications needed for the Cross Support Reference Model? InformalMay 2009 We will present the Red Books at IOAG-13 in the fall of 2009.

6 Status of Each Item Defined in the Charter  Development of a Space Communication Cross Support Architecture recommended practice  The White Book on Cross Support Service Architecture (CSSA) provided by IOAG is being reviewed.  Development of a recommended standard for service catalogs  The tables of attributes to be used to characterize services provided by IOAG are being reviewed.  Development of a recommended standard for service agreements  The service agreement template provided by IOAG and some other sample service agreements are being reviewed.  A draft service agreement template is being generated.

7 Resource Driven Approach for Developing Deliverables Cross Support Service Architecture (CSSA WB) It already covers in-space services and contains templates for service catalogs and service agreements. Available resources Space Communication Cross Support Architecture (MB) Cross Support Service Catalogs (BB) Cross Support Service Agreement (BB) We need to identify what to add to the IOAG WB

8 How to Develop the Space Communications Cross Support Architecture  The IOAG CSSA WB should be used as the baseline.  We should identify descriptions missing from the WB and descriptions unnecessary in the WB.  Descriptions we can potentially borrow from NASA’s ADD: management functions, service discovery, etc.  We should determine the scope of this book (see another presentation).  Goals of this meeting:  Review the results of the action items assigned at the previous meeting.  Generate a list of things to be added to and deleted from the WB.  Identify a contributor to generate text to be added to the WB.

Discussion Items on the Architecture Book  Scope of the book. Should we recommend or refer to particular services?  Can we replace CSRM with this book?  How to incorporate materials from NASA’s ADD.  Do we need an Information View?  Space Communications Scenario  Terms (Forward, Return, etc.) 11

12 How to Develop the Service Catalogs  The tables of attributes contained in Annexes A-E of the CSSA WB should be used as the baseline.  We should identify the following: 1. attributes missing from the tables for characterizing services 2. attributes unnecessary in the tables for characterizing services  Then, we should develop a few sample catalogs using the agreed-to attributes.  Goals of this meeting:  Agree on a set of attributes for some typical cross support services.

14 How to Develop the Service Agreements  The template for service agreements should be generated based on Annex F of the CSSA WB, some existing service agreements, SLE SM RB.  We should agree on a set of attributes that should be contained in every service agreement.  Then we should develop a few sample service agreements using the agreed-to template.  Goals of this meeting:  Agree on a core set of attributes.  Generate a few sample service agreements.
