SCaN Future Architecture“Architecture is a creative art, even if it is based on an existing legacy system. It is not only for engineering or construction guidance, but it also has to provide insight, intent, and vision, so that it can guide the system in moving forward through continual evolution.”

Dr. Yan Zhao; CGI Federal Director for Enterprise and Solutions Architecture

End-to-End IP Network ArchitectureThe Constellation Project has established the initiative to extend communication infrastructures based on IP protocol from ground segment to flight/space segment to achieve interoperability among its elements. SCaN Networks can accommodate IP Service Interfaces to CxP systems.

Looking Forward

• System Interoperability

• Cross-Organizational Interfaces and Decision Making Processes

• Software Architecture and Lifecycle

• Horizontal Technical Coordination and Integration

• Architecture Cost-benefit Analysis

• Developing NASA-Wide Architecting Process– Levels and Stages (Definition, Description and Design)

• Architecture Performance and Evaluation

• Integration of Architecture with Requirements and ConOps

• Implementation Follow-up
