SISG ConOps
Operational Scenarios

Operational Scenario Diagrams
• This package includes a set of operational scenarios reflecting a nominal SISG
Space Internetworking allocation of functionality to system elements
• These are intended to be relevant for a future typical SISG deployment where agencies support
standard services for service management, network control, and space internetwork operation
• Variations on these charts could be developed to show the differences between current operations
scenarios and this future view
• Major Features:
• High level set of nominal operational scenarios
• Representation of time sequencing of activities
• Representation of functions/activities external to each scenario
• Use of colors to associate functions to the high level allocations
• User Mission System (MOC & Spacecraft, shown as white box)
• Service Management
• Network Control
• Service Execution
• The technical content for this material was primarily derived from:
• SISG ConOps, revised 18 Sep 09
• NASA SCaN ConOps scenarios
Definition of Terms
• Scenario:
• A specific sequence of activities conducted by the the SISG
network elements and/or Mission User MOC to accomplish support
for one or more mission events.
• Activity:
• A specification of system behavior described by a sequence of one
or more actions performed by the SISG network elements and/or
Mission User MOC.
• Function:
• The set of actions or activities performed by some object to achieve
a goal. The transformation of inputs to outputs that may include the
creation, modification, monitoring, or destruction of elements.
• Action:
• Something that happens within an object, either with or without
participation of another object.
Operational Scenarios
Introduction to Chart Style
• Charts use a “swimlane” approach similar to UML activity diagrams
• Each swimlane relates to a specific element of the system
• User Mission System (MOC & Spacecraft, shown as white box)
• Network Control
• Service Management
• Service Execution
• Each of the major scenarios is shown on the overview diagram and then described
in more detail on a separate diagram
• For each major scenario the predecessor scenarios and data sources are shown as
Service
are the successor scenarios, as rounded grey boxes 5.1Planning
• All of the scenarios show the relevant set of activities and data source / sinks as
Conduct
rectangular white boxes Mission
Planning
• The typical order of activities is indicated by a numbered sequence 1 , in some
cases there is iterative behavior
• The Network Management functions (Service Management & Network Control)
operate all network assets of the SISG Space Internetwork
• The TT&C Service Execution functions, during operations, include all activities from
the feed horn at the receiving / transmitting antenna to / from the data delivery
interface
