MarkovClassifier

simple module

This module implements a packet classifier using a Markov process that has as many states as output gates the classifier has. The output gate for a given packet is determined by the current state of the Markov process.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name	Type	Description
PacketClassifierBase	simple module	This is a base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"classified %p pk (%l)\ncurrent state: %s"	determines the text that is written on top of the submodule
reverseOrder	bool	false
clockModule	string	""	relative path of a module that implements IClock; optional
initialState	int	0	the index of the start state of the Markov process
transitionProbabilities	string		the transition matrix (N x N) of the Markov process, specified as a list of probabilities
waitIntervals	string		the amount of time the Markov process stays in a given state, a list of intervals (N) indexed by the state
