Detailed Description

Abstract base class for differential forwarding message processing.

DTN::Application::process() is left unimplemented in this class, as is Mobility::MobileApp::newNeighbor(). This should be added to a Mobility::MobileNode using addMobileApp(), rather than addApplication(). The former calls the latter, as well as adding the application to a separate list of apps to notify when a new neighbor comes into view.

Constructor & Destructor Documentation

DFApp::DFApp	(	const struct timeval &	timeout,
		DTN::Link *	link
	)

Constructor.

Parameters:

	timeout	The maximum duration without receiving a beacon after which we determine that a node is no longer visible
	link	The real link on which bundles are sent (not owned)

Definition at line 38 of file DFApp.cc.

Member Function Documentation

virtual DTN::Link* DifferentialForwarding::DFApp::linked

(

const DTN::ByteString &

dest

)

[pure virtual]

Find a node to which we can send data.

Parameters:

dest

The destination address

Returns:

a link on which to send, or NULL if there is nothing appropriate

Referenced by DifferentialForwarding::DFPolicy::forward(), and DifferentialForwarding::DFPolicy::forwardOn().

virtual DTN::Bundle* DifferentialForwarding::DFApp::createBeacon

(

)

[protected, pure virtual]

Generate our beacon to broadcast to neighbors.

Returns:

a new bundle, passing ownership to the caller

Referenced by beacon().
