Measuring Residence Time¶
Goals¶
In this example we explore the packet residence time statistics of network nodes.
INET version:
4.4
Source files location: inet/showcases/measurement/residencetime
The Model¶
The packet residence time is measured from the moment a packet enters a network node up to the moment the same packet leaves the network node. This statistic is also collected for packets which are created and/or destroyed in network nodes.
Here is the network:

Here is the configuration:
[General]
network = ResidenceTimeMeasurementShowcase
description = "Measure packet residence time in all network nodes"
sim-time-limit = 1s
# source application ~96Mbps throughput
*.source.numApps = 1
*.source.app[0].typename = "UdpSourceApp"
*.source.app[0].source.packetLength = 1200B
*.source.app[0].source.productionInterval = exponential(100us)
*.source.app[0].io.destAddress = "destination"
*.source.app[0].io.destPort = 1000
# destination application
*.destination.numApps = 1
*.destination.app[0].typename = "UdpSinkApp"
*.destination.app[0].io.localPort = 1000
# enable packet residence time measurer in all network nodes
*.*.measurer.typename = "ResidenceTimeMeasurer"
