Package: inet.queueing.marker


simple module

Sets Explicit Congestion Notification (ECN) bits in IPv4 header based on the attached EcnReq tag on the packets.

Inheritance diagram

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


Name Type Description
PacketMarkerBase simple module

This is a base module for various packet marker modules. Derived modules must implement a single markPacket() function which marks the individual packets by attaching tags.


Name Type Default value Description
displayStringTextFormat string "marked %p pk (%l)"

determines the text that is written on top of the submodule


Name Value Description
display i=block/rightarrow
class EcnMarker


Name Direction Size Description
in input
out output


Name Type Unit
packetPushedIn inet::Packet
packetPulledIn inet::Packet
packetPushedOut inet::Packet
packetPulledOut inet::Packet
