Detailed Description

Abstract Channel Base Class.

A channel is a logical path over which information flows. The path can be as simple as a short piece of wire, or as complicated as space-time.

Subclasses must use Simulator::ScheduleWithContext to correctly update event contexts when scheduling an event from one node to another one.

Config Paths

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

"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Channel"
"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phy/Channel"
"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phys/[i]/Channel"
"/ChannelList/[i]"

Attributes

Id: The id (unique integer) of this Channel.
- Set with class: ns3::UintegerValue
- Underlying type: uint32_t 0:4294967295
- Flags: read

No TraceSources are defined for this type.
Size of this type is 32 bytes (on a 64-bit architecture).

Member Function Documentation

◆ GetDevice()

virtual Ptr< NetDevice > ns3::Channel::GetDevice ( std::size_t i ) const

pure virtual

Parameters

i	index of NetDevice to retrieve

Returns: one of the NetDevices connected to this channel.

This method must be implemented by subclasses.

Implemented in ns3::BridgeChannel, ns3::CsmaChannel, ns3::ErrorChannel, ns3::SimpleChannel, ns3::PointToPointChannel, ns3::MultiModelSpectrumChannel, ns3::SingleModelSpectrumChannel, ns3::UanChannel, ns3::YansWifiChannel, and ns3::WimaxChannel.

◆ GetId()

uint32_t ns3::Channel::GetId ( ) const

Returns: the unique id of this channel

This unique id happens to be also the index of the Channel into the ChannelList.

References m_id, and NS_LOG_FUNCTION.

◆ GetNDevices()

virtual std::size_t ns3::Channel::GetNDevices ( ) const

pure virtual

Returns: the number of NetDevices connected to this Channel.

static

Get the type ID.

Returns: the object TypeId
