SISG ConOps Operational Scenarios

1. SISG ConOpsOperational Scenarios DRAFT Space Internetworking Strategy Group Peter Shames 19 Sept 2009

2. 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

3. 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.

4. 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 are the successor scenarios, as rounded grey boxes • All of the scenarios show the relevant set of activities and data source / sinks as rectangular white boxes • The typical order of activities is indicated by a numbered sequence , 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 1 5.1 Service Planning Conduct Mission Planning
