StreamSplitter¶

Package: inet.protocolelement.redundancy

simple module StreamSplitter

Duplicates incoming packets based on the stream they are part of. The stream is determined by the StreamReq tag that is attached to the packet. The number of outgoing packets is determined by the mapping parameter. Each outgoing packet will have an attached StreamReq with the tag name taken from the mapping parameter.

Used in compound modules¶

Name	Type	Description
StreamRelayLayer	compound module	Combines a stream merger and a stream splitter module into a stream relay layer. For incoming packets, the identified streams are merged by the stream merger. For outgoing packets, the requested streams are split by the stream splitter.

Extends¶

Name	Type	Description
PacketPusherBase	simple module	Base module for various packet pusher modules.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
mapping	object	{}	Map from input stream names to array of output stream names, empty string means no stream

Properties¶
