Scenario Explorer

The Scalable Network Modeling Interface Scenario Explorer displays the scenario configuration, hierarchy of STK object nodes, and network connections (wireless subnets, applications and links). Use the Scalable Network Modeling Interface Scenario Explorer to:

Define the Scenario Configuration

Scalable Network Modeling Interface parameters of interest to Scalable Network Modeling Interface users are:

  • General
    • Experiment Name. Enter a name that applies to the files generated from the Scalable Network Modeling Interface run.
    • Simulation Time. Inherited from the STK Scenario Analysis Period.
  • Channel Properties
    • Number of Channels. Indicate the number of channels.
    • Rain Outage Percent. The maximum percent outage for the rain model.
  • File Statistics
    • Select the types of statistics to be plotted.

To display an item's properties and values, click on that item in the explorer window. For information on more Scenario Configuration parameters, see the Scalable Network Modeling Interface documentation.

Build a Scenario Hierarchy

A scenario hierarchy is composed of nodes. Nodes communicate with each other through connected network interfaces. Each node must have at least one network interface for it to be considered in the network analysis. To define the configuration and network interfaces of a node hierarchy, note the following:

  1. Any applicable STK object that was added using STK displays under Hierarchy in the Scalable Network Modeling Interface. Use STK to add any additional required nodes to the STK Scalable Network Modeling Interface scenario. Nodes appears in the Scalable Network Modeling Interface Explorer window as they are added in STK. You must use STK to add all STK objects, except for antenna and sensors. You can also use the Scalable Network Modeling Interface to add antennas and sensors. Antennas and sensors added using the Scalable Network Modeling Interface are also displayed in the STK Object Browser.
  2. Under each node is the default configuration for that node. The default configuration contains File Statistics selections inherited from the Scenario Configuration. Make any desired changes for each node by clicking on File Statistics under Node Configuration. For more information on node configuration parameters, see the Scalable Network Modeling Interface documentation.
  3. You can define one or more network interfaces for each node in the hierarchy folder. A network interface is a connection instance between a transmit antenna and a receive antenna. A node requires one interface for each network connection instance. When you add a new node into the hierarchy folder, STK will add a one network interface automatically for certain objects. For antenna objects, the default network interface is a wireless network interface. For Facility, Place, and Target objects, the default network interface is a wired interface. To add another network interface, right-click the node to select the type of interface you want (wired or wireless). For more information, click Network Interface.

A network interface must be part of a network connection to be considered in the network analysis.

You can configure a scalable network using Connect Commands through the STK Connect Client. Read more about Connect Commands for Scalable Networks.

Create Network Connections

The Scalable Network Modeling Interface enables you to create and define network connections for:

  • Wireless subnets . All wireless subnets are added to this folder. A wireless subnet requires at least two available interfaces. A interface is considered unavailable if it is a member of another subnet. For more information, click Add Wireless Subnet.
  • Wired subnets . All wired subnets are added to this folder. A wired subnet requires at least two available interfaces. A interface is considered unavailable if it is a member of another subnet.
  • Applications . An application link requires a source node, a destination node, and an application type. Each application link sends a start time, stop time, precedence, item size and number of items. For more information, click Add Application.
  • Links . A point-to-point link requires two available node/interfaces. For more information, click Add Link.

To add a network connection, right-click Connections and select Add Application..., Add Link...,or Add Wireless Subnet....
