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

2. 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 Operational Scenario Diagrams

3. 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. Definition of Terms

4. 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 Operational Scenarios Introduction to Chart Style 5.1 Service Planning Conduct Mission Planning 1
