LinkVisualizerBase

simple module

This is a base module for 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 the corresponding 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.

This module subscribes for signals at the provided subscription module. When determining active links, it only considers packets matched by the provided filters. The filters use the format of cMatchExpression with the packet name as the default attribute.

The format string can contain the following directives:

  • %n packet name
  • %c packet class

Known subclasses

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.

PhysicalLinkVisualizerBase simple module

This is a base module for physical 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 physical 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.

Extends

Name Type Description
VisualizerBase simple module

This is a base module for visualizer simple modules. It simply provides the visualization target module for derived modules.

tags string ""

tag added to each visualization for disambiguation in the runtime environment

displayLinks bool false

display arrows for active links, disabled by default

activityLevel string "service"

determines what level of activity is displayed, service level by default

nodeFilter string "*"

which nodes are considered, matches all nodes by default

interfaceFilter string "*"

link arrow style (solid, dashed, dotted)

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 "black"

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
