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.

// This module subscribes for packetReceivedFromUpper and packetSentToUpper on
// the module determined by the visualizationSubjectModule parameter. If the visualizer
// receives a packetReceivedFromUpper from a MAC protocol module, then it stores
// the corresponding packet id. If later on the visualizer receives a
// packetSentToUpper from another MAC protocol module with the same packet id,
// then it adds an active link between the source and the destination nodes.
// After a certain amount of time the link becomes inactive unless it is
// reinforced by another packet.
