DataLinkOsgVisualizer

simple module

This module visualizes data link layer links on a 3D osg scene. It displays an arrow for each active link in the network. See the documentation of the base module for what constitutes an active link. The arrow points from the source towards the destination. If a link is used in both directions then there are separate arrows for them. Each arrow fades out over time as the link becomes inactive unless it is reinforced by another packet. The arrow automatically follows the movement of mobile nodes.

Extends

Name Type Description
DataLinkVisualizerBase simple module

This is a base module for data link layer link visualizer simple modules. It keeps track of active links in a network. A link between two network node is considered active if a packet is sent recently between their link layers. Active links are not displayed by default, see the module parameters for how to enable the visualization. The actual visualization of active links is done in derived modules.

Parameters

Name Type Default value Description
visualizationTargetModule string "^"

module path relative to the visualizer which determines where the visualization should appear in the user interface, parent module by default

visualizationSubjectModule string "^"

module path relative to the visualizer which determines what part of the simulation model the visualizer displays in the user interface, parent module by default

tags string ""

tag added to each visualization for disambiguation in the runtime environment

displayLinks bool false

display arrows for active links, disabled by default

lineWidth double 3

link arrow width

lineShift double 16

line shift to avoid overlapping arrows

lineShiftMode string "normal"

determines how overlapping arrows are shifted, possible values are: none, normal, x, y, z; optional prefix + or -

lineContactSpacing double 3

spacing between arrow end and submodule icon

lineContactMode string "rectangular"

determines how arrows are clipped at the submodules

labelFormat string "%n"

determines what link data is displayed

labelFont string ", 8px"

label font, automatic by default

labelColor string "darkcyan"

label color, black by default

fadeOutMode string "realTime"

specifies how inactive links fade out

fadeOutTime double 1s

how quickly inactive links fade away, 1 second by default

fadeOutAnimationSpeed double 0

animation speed while there are active links, value must be in the range (0, +inf)

holdAnimationTime double 0s

hold simulation (no progress) for the specified amount of animation time when the link is activated
