Detailed Description

This class implements a device which does not communicate, in the sense that it does not interact with the above protocol stack.

The purpose of this NetDevice is to be used for devices such as microwave ovens, waveform generators and spectrum analyzers. Since the ns-3 channel API is strongly based on the presence of NetDevice class instances, it is convenient to provide a NetDevice that can be used with such non-communicating devices.

Config Paths

ns3::NonCommunicatingNetDevice is accessible through the following paths with Config::Set and Config::Connect:

"/NodeList/[i]/DeviceList/[i]/$ns3::NonCommunicatingNetDevice"

Attributes

- Set with class: ns3::PointerValue
- Underlying type: ns3::Ptr< ns3::Object>
- Initial value: 0
- Flags: constructwriteread

No TraceSources are defined for this type.
Size of this type is 88 bytes (on a 64-bit architecture).

Member Function Documentation

◆ AddLinkChangeCallback()

void ns3::NonCommunicatingNetDevice::AddLinkChangeCallback ( Callback< void > callback )

overridevirtual

Parameters

callback the callback to invoke

Add a callback invoked whenever the link status changes to UP. This callback is typically used by the IP/ARP layer to flush the ARP cache and by IPv6 stack to flush NDISC cache whenever the link goes up.

packet	packet sent from above down to Network Device
dest	mac address of the destination (already resolved)
protocolNumber	identifies the type of payload contained in this packet. Used to call the right L3Protocol when the packet is received.

packet	packet sent from above down to Network Device
source	source mac address (so called "MAC spoofing")
dest	mac address of the destination (already resolved)
protocolNumber	identifies the type of payload contained in this packet. Used to call the right L3Protocol when the packet is received.
