C++ definition

Connects one packet collector to multiple packet providers. It can be pulled for packets by the connected packet collector. When this happens, the scheduler pulls a packet from one of its packet providers based on the configured packet filters. The first matching expression determines the index of the input gate.

Inheritance diagram

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

Name	Type	Description
ContentBasedSchedulerTutorialStep	network	(no description)

Extends

Name	Type	Description
PacketSchedulerBase	simple module	Base module for various packet scheduler modules. Derived modules must implement a single packet scheduler function which determines the index of the input gate for the pulled packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"scheduled %p pk (%l)"	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
reverseOrder	bool	false
defaultGateIndex	int	0	Default gate index if no matching labels are found
packetFilters	object		Array of packet filter expressions
