Detailed Description

Network device transmission queue interface.

Introspection did not find any typical Config paths.

This interface is used by the traffic control layer and by the aggregated device to access the transmission queues of the device. Additionally, through this interface, traffic control aware netdevices can:

  • set the number of transmission queues
  • set the method used (by upper layers) to determine the transmission queue in which the netdevice would enqueue a given packet NetDevice helpers create this interface and aggregate it to the device.


Attributes

  • NTxQueues: The number of device transmission queues
    • Set with class: ns3::UintegerValue
    • Underlying type: uint16_t 1:65535
    • Initial value: 1
    • Flags: constructread
  • TxQueuesType: The type of transmission queues to be used

No TraceSources are defined for this type.
Size of this type is 136 bytes (on a 64-bit architecture).
