C# Class Ipop.Ethernet

Provides an interface to the Virtual Network device known as a TAP device. Ethernet is an ISender, meaning to write to the device, one must call the Send method. It is also an ISource, meaning to receive packets one must subscribe via the Subscribe method to the output.

Inheritance: SimpleSource, ISender

Public Methods

Method	Description
Ethernet ( string device_name ) : Brunet	Initializes the Ethernet device by opening the TAP device and starting the ISource thread.
Send ( ICopyable data ) : void	Writes the data to the Ethernet device. The same max MTU byte array is always used to write the data to the device. Since the incoming data is an ICopyable, it needs to be copied to a single byte array before being sent to the unmanaged language.
Stop ( ) : void	Call this method when exiting to stop the _read_thread.
ToUri ( ) : String

Protected Methods

Method	Description
ReadLoop ( ) : void	The thread acting as the ISource for Ethernet, this is where reading of the TAP is performed. Use Subscribe to receive the packets coming from here. The same max MTU byte array is always read into. This is then copied to a minimum sized MemBlock and send to the subscriber.

Method Details

Ethernet() public method

Initializes the Ethernet device by opening the TAP device and starting the ISource thread.

public Ethernet ( string device_name ) : Brunet
device_name	string
return	Brunet

ReadLoop() protected method

The thread acting as the ISource for Ethernet, this is where reading of the TAP is performed. Use Subscribe to receive the packets coming from here.

The same max MTU byte array is always read into. This is then copied to a minimum sized MemBlock and send to the subscriber.

protected ReadLoop ( ) : void
return	void

Send() public method

Writes the data to the Ethernet device.

The same max MTU byte array is always used to write the data to the device. Since the incoming data is an ICopyable, it needs to be copied to a single byte array before being sent to the unmanaged language.

public Send ( ICopyable data ) : void
data	ICopyable	ICopyable of the data to be written.
return	void

Stop() public method

Call this method when exiting to stop the _read_thread.

public Stop ( ) : void
return	void

ToUri() public method

public ToUri ( ) : String
return	String
