Detailed Description
Simple Point To Point Channel.
This class represents a very simple point to point channel. Think full duplex RS-232 or RS-422 with null modem and no handshaking. There is no multi-drop capability on this channel – there can be a maximum of two point-to-point net devices connected.
There are two "wires" in the channel. The first device connected gets the [0] wire to transmit on. The second device gets the [1] wire. There is a state (IDLE, TRANSMITTING) associated with each wire.
Constructor & Destructor Documentation
| ns3::PointToPointChannel::PointToPointChannel | ( | ) |
Create a PointToPointChannel.
By default, you get a channel that has zero transmission delay.
References NS_LOG_FUNCTION_NOARGS.
Member Function Documentation
| void ns3::PointToPointChannel::Attach | ( | Ptr< PointToPointNetDevice > | device | ) |
Attach a given netdevice to this channel.
- Parameters:
-
device pointer to the netdevice to attach to the channel
References NS_ASSERT, NS_ASSERT_MSG, and NS_LOG_FUNCTION.
Referenced by ns3::PointToPointNetDevice::Attach().
- Parameters:
-
i index of NetDevice to retrieve
- Returns:
- one of the NetDevices connected to this channel.
This method must be implemented by subclasses.
Implements ns3::Channel.
References NS_LOG_FUNCTION_NOARGS.

virtual |
Get number of devices on this channel.
- Returns:
- number of devices on this channel
Implements ns3::Channel.
