Member Function Documentation

◆ createLink()

Link * simgrid::surf::NetworkNS3Model::createLink	(	const char *	name,
		double	bandwidth,
		double	latency,
		e_surf_link_sharing_policy_t	policy
	)

overridevirtual

Create a Link.

Parameters

name	The name of the Link
bandwidth	The initial bandwidth of the Link in bytes per second
latency	The initial latency of the Link in seconds
policy	The sharing policy of the Link

Implements simgrid::surf::NetworkModel.

◆ communicate()

Action * simgrid::surf::NetworkNS3Model::communicate	(	s4u::Host *	src,
		s4u::Host *	dst,
		double	size,
		double	rate
	)

overridevirtual

Create a communication between two hosts.

It makes calls to the routing part, and execute the communication between the two end points.

Parameters

src	The source of the communication
dst	The destination of the communication
size	The size of the communication in bytes
rate	Allows to limit the transfer rate. Negative value means unlimited.

Returns: The action representing the communication

Implements simgrid::surf::NetworkModel.

◆ nextOccuringEvent()

double simgrid::surf::NetworkNS3Model::nextOccuringEvent ( double now )

overridevirtual

Share the resources between the actions.

Parameters

now	The current time of the simulation

Returns: The delta of time till the next action will finish

Reimplemented from simgrid::surf::Model.

◆ nextOccuringEventIsIdempotent()

bool simgrid::surf::NetworkNS3Model::nextOccuringEventIsIdempotent ( )

inlinevirtual

Returns whether this model have an idempotent shareResource()

The only model that is not is NS3: computing the next timestamp moves the model up to that point, so we need to call it only when the next timestamp of other sources is computed.

Reimplemented from simgrid::surf::Model.

◆ updateActionsState()

void simgrid::surf::NetworkNS3Model::updateActionsState	(	double	now,
		double	delta
	)

overridevirtual

Update action to the current time.

Parameters

now	The current time of the simulation
delta	The delta of time since the last update

Reimplemented from simgrid::surf::Model.
