Configurations

There are some predefined configurations for the simulators and nodes.

Simulator configurations

There is a list for simulator configurations.

All these configurations have default values, usually you do not need to change them unless you have special requirements. They are in SimulatorConfigurator class in the configurator package. But we suggest you to modify them in our user interface.

Option	description
volumePath	The address where the TEQ file is mounted inside the container
volumeFolderName	The external folder that will be mounted inside the container will contain all the resources that need to be used within the container
startScriptName	The name of the script that will be executed when the container starts
startPackageName	TEQ will generate a java package with this name to start the simulation process in docker containers
startClassName	the starter class name in the starter package
imageName	The name of the image that will be used to create the container, image provided by TEQ is recommended
tcpPort	The port used to connet the docker daemon
getStdout	when enabled, the stdout of the container will be printed to the console
defaultLayerNamePrefix	the prefix of the layer name when you do not specify a name for a layer.(these layer whill be named as 'layer0', 'layer1', 'layer2', ...)
metricsPort	All the containers will send their individual metrics to NetworkHost node at this port
MetricsReceiverPort	The NetworkHost node will aggregate all the metrics and send them to the host(the main process) at this port.This means the inner docker network and the main process will communicate through this port
restfulPort	The port used to send data to the front end(User Interface)
classNamePrefix	All the container names will have this prefix to identify them
cleanUpAfterSimulation	When enabled, the container will be removed after the simulation is finished
displayInterval	The interval of the metrics transformation,the metrics will be transformed and sent to the front end every displayInterval milliseconds

Nodes configurations

There is a list for node configurations.

All these configurations have default values, you can change them to simulate different scenarios in edge computing.They are in DockerNodeParameters class in the node package. But we suggest you to modify them in our user interface.

All the configurations will be applied in real time during the simulation.

Option	description
cpuUsageRate	percentage of the cpu usage rate, 0.5 means 50%, it can be larger than 1(means using more than 1 core)
memorySize	unit: GB
networkOutBandwidth	the bandwidth of the network out for this node, unit: kbps
networkOutLatency	the latency of the network out for this node, unit: ms
networkInBandwidth	unit: kbps
networkInLatency	unit: ms
fixedInLatency	when this is not 0, the network in latency will be fixed to this value, unit: ms
fixedOutLatency	when this is not 0, the network out latency will be fixed to this value, unit: ms
