IActivePacketSink¶

module interface IActivePacketSink

Interface for active packet sink modules. An active packet sink, also called a collector, has one input that must be connected to a passive packet source module. The active packet sink is expected to pull packets from the connected passive packet source over time.

Inheritance diagram¶

Implemented by¶

Name	Type	Description
PacketDemultiplexer	simple module	Connects multiple packet collectors to one packet provider. When a packet is pulled by one of the connected packet collectors, then the demultiplexer simply pulls a packet from the connected packet provider.
InstantServer	simple module	Repeatedly pulls packets from the connected packet provider and pushes the packet into the connected packet consumer without delay.
OmittedPacketServer	compound module	Implements the given interface and can be used as an optional module that removes itself from the module hierarchy during initialization.
PacketServer	simple module	Repeatedly pulls packets from the connected packet provider and after a processing delay, it pushes the packet into the connected packet consumer. The processing delay is `processingTime` + `packetLength` / `processingBitrate`.
PreemptingServer	simple module	(no description)
TokenBasedServer	simple module	Repeatedly pulls packets from the connected packet provider and it pushes them into the connected packet consumer. The packets are processed in zero simulation time, and the process continues until the available number of tokens is not sufficient anymore.
ActivePacketSink	simple module	An active packet sink which pulls packets from the connected module. It pulls whole packets through the in gate at every collection interval. It pulls the first packet after the initial collection offset.
FullPacketSink	simple module	An active/passive full packet sink. It doesn’t pull packets from the connected module, and it doesn’t allow packets to be pushed by the connected module. The input gate generates backpressure for push packet operations.

Known subclasses¶

Name	Type	Description
IPacketPuller	module interface	Interface for packet pullers. A packet puller connects one input to one output. Packets can be pulled from its output and it pulls packets from its input.
IPacketServer	module interface	Interface for packet server modules. A packet server is an active module which has one active input and one active output. Packets are pulled from the connected input module and pushed into the connected output module with an optional delay but without reordering.
