Name	Type	Description
EthernetQueue	compound module	Queue module that gives the PAUSE frames a higher priority.
EthernetQosQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and can be parametrized with an IPacketQueue for serving the data frames.
EthernetQosRedQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and using Random Early Detection algorithm on data frames, and can be parametrized with an IPacketQueue for serving the data frames.
