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.

Inheritance diagram

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

Known subclasses

Name	Type	Description
BehaviorAggregateClassifier	simple module	This module reads the DSCP (lower six bits of ToS/TrafficClass) from the received datagram, and forwards the datagram to the corresponding output gate.
ContentBasedClassifier	simple module	This module connects one packet producer to multiple packet consumers. It can be pushed with packets from the connected packet producer. When this happens, the classifier pushes the packet to one of its connected packet consumers based on the configured packet filters. The first matching expression determines the index of the output gate.
EtherFrameClassifier	simple module	Classifier that forwards Ethernet PAUSE frames to the pauseOut gate, and other frames to the defaultOut gate.
LabelClassifier	simple module	This module classifies packets based on the attached labels in a LabelsTag.
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.
MultiFieldClassifier	simple module	This classifier contains a list of filters that identifies the flows and determines their classes. Each filter can match the source and destination address, IP protocol number, source and destination ports, or ToS of the datagram. The first matching filter determines the index of the out gate. If no matching filter is found, then the packet will be sent through the defaultOut gate.
PacketClassifier	simple module	This module connects one packet producer to multiple packet consumers. It can be pushed with packets from the connected packet producer. When this happens, the classifier pushes the packet to one of its connected packet consumers based on the configured packet classifier function. The packet classifier function takes a packet and returns an integer which in turn is used for determining the output gate.
PriorityClassifier	simple module	This classifier pushes packets into the first non-full among its connected packet consumers.
WrrClassifier	simple module	This module implements weighted round-robin classifier.
